Super Spiro mk2 - System Overview (Fig. 1)
The Micro Medical Super Spiro is a data recording spirometer consisting of a microcomputer
unit (1) incorporating a 1/4VGA colour LCD display, data entry keypad, RS232 serial interface, USB
interface and all associated circuitry. It is supplied with a digital volume transducer (2), disposable
mouthpieces, transducer holder (3) and mains adapter (4). The Super Spiro is powered by a
universal mains adapter (4).
When testing a subject the transducer is inserted into the holder which is plugged into the
microcomputer unit. The digital volume transducer is used to measure the subjects expired flow and
volume in accordance with the operating manual.

Transducer (Fig. 2)
The Micro Medical digital volume transducer consists of an acrylic tube with a vane positioned
between two swirl plates. The low inertia vane is attached to a stainless steel pivot, which is free to
rotate on two jewelled bearings mounted at the centre of the swirl plates. As air is passed through the
transducer the swirl plates create a vortex, which causes the vane to rotate in a direction dependant
upon the direction of airflow. The number of rotations is proportional to the volume of air passed
through the transducer and the frequency of rotation is proportional to the flow rate. The transducer
housing consists of a main body that contains a pair of light emitting diodes (LED’s) and
phototransistors. The transducer is fixed to the mouthpiece holder which pushes into the main body
and is captured by an “O” ring seal. The LED’s produce infra red beams which are interrupted by the
vane twice per revolution. This interruption is sensed by the phototransistors. The output from the
collector of each phototransistor will be a square wave with a phase difference between the two of +
or - 90 degrees depending upon the direction of flow.
There is no routine maintenance required for the transducer other than cleaning according to
the instructions in the operating manual.

Circuit Description, (see 078-01)
The Super Spiro mk2 board was designed primarily to interface with the Micro Medical Spirometer
turbine, but the interface was kept open ended so that other modules, for example, airways resistance
by the interrupter method (Rint) can be attached. A 9 pin ‘D’ type connector was designed in to allow
‘customer special’ modules to be attached and the unit is also USB compatible.
Provision was given to add a mezzanine board for customer special interface circuitry to be
connected.
Microprocessor circuit (Drawing 078-02)
The Super Spiro mk2 is controlled by Renesas (formally Hitachi) HD64F2319 micro controller (uC)
U2. It has in built 512 KByte flash memory and 8 KByte of RAM. The flash memory is used for boot
loader and kernel, whilst the internal RAM is used as a stack only. The uC clock speed is set at
24.567 MHz by crystal X1. This clock divides properly for 115K baud rate for serial port. Although the
USB is the primary interface port, the serial port is used for downloading the boot loader and initial
board testing.
Since the uC internal RAM is not sufficient, an external 1 MByte RAM (U3) is used for running the
modules and data manipulation. U5 is a fairly large flash memory utilised as a flash Disk. It stores
various modules and data as files. The modules are loaded in RAM before executing. The data like
spirometry records, patient information ect. Are saved as database files. U6 controls read/write
signals to U5. The reset controller U1, controls the reset line to the uC and the rest of the system. If
the supply voltage falls below 3.1 V, it reset the uC. The uC can hold itself in ON position, despite the
user trying to switch itself off using TR1. This is necessary to prevent the system switching off whilst
the uC is writing data to the flash disk. Similarly, it can turn itself off using TR2 for battery saving.
J3 is the connector to display backlight, with power and backlight on/off control using TR4. LK1 is
shorted to download the boot loader for the first time. There after, it is not normally used, except to
load the new updated version of the boot loader.
Keypad Circuit (Drawing 078-12)
The keypad is connected as 4 X 4 matrix. The software can determine which key is pressed by driving
a pattern to one side of the matrix and reading the result. The pattern switches on one row and the
corresponding result specifies which column the pressed key belongs to. Diode arrays D1 and D2 are
required to control the matrix.
There are six dedicated keys for display contrast, sound volume paper feed and On/Off. These keys
directly control the hardware and are not software driven. LED1 indicates if the battery charger is
connected.
The keypad circuit is a separate board which holds the actual keys. It connects to the main board via
connector J1.
8
RTC and Keypad Interface (Drawing 078-05)
J7 connects the keypad board to the main board. U21 is use for generating interrupt if any key is
pressed.
U22 is an RS232 interface chip, converting logic (3V3) Rx and Tx line to RS232 level signals. It has in
built step up and power inverter, generating +- 6V6. It requires capacitors C57 – C60 to do this
conversion. J6 is 9 pin D type RS232 connector. It has standard pin outs except for pin 4 which has
3V3 power. This could be useful in the future to supply power to an interface board.
U24 is a Phillips Real Time Clock (RTC) device. It keeps the current time and date. When the unit is
switched off, it is powered from the rechargeable battery. It draws very little current, and therefore can
stay on for years without draining the battery significantly.
U25 is a temperature sensor, located on one corner of the board. It measures current ambient
temperature for inspiratory calculations.
U23 is 32 byte EEPOM to store system parameters. Most of the system parameters can be stored in
the flash disk, but some parameters like the calibration values, serial number etc. are best stored
here. If the flash disk is formatted, these parameters are not lost.
Printer Driver Circuit (Drawing 078-06)
The in built thermal printer is controlled by a separate micro controller U26. The uC is a Renesas
H3687 Tiny series with 56 Kbyte internal flash and 512 bytes of RAM. The uC controls the thermal
printer heads and drives the motor to turn the paper. U27 is a high power motor controller. The
interface from main uC is via logic level RS232. Since this uC requires 5V supply, the interface signals
are converted from 3V3 to 5V by U28. The software to this uC can be upgraded by turning on TR10
and resetting the uC. This puts the uC in boot mode and software can be programmed in the internal
flash via the serial port.
VR1 resistance value is read by the uC to control the switch on printer head time. This enables
lighter/darker dots on the paper. This is set during production and is not available to the user.
Power Supply (Drawing 078-03)
The Super Spiro mk2 requires various power supply for different devices. On top of this, it should
work from the internal rechargeable battery or from mains power converter (9 V) and should recharge
the battery.
If the mains power is connected, the battery output is switched off by TR5. All the power to the system
is from the mains power module, except the on/off controller. At the same time, the battery is charged
by power controller U9, which ensures that steady 9V is applied to the battery.
When the mains power module is not connected, then the battery supplies all of the power to the
system. It also powers the on/off JK flip flop, which turns on TR6 when on/off key is pressed, and
turns off when the key is pressed again. U43 is a rail to rail comparator which ensures that the unit
can not be turned on when the battery voltage falls below a minimum level. The minimum level is set
to ensure that there is always some battery power available to run the real time clock and enough to
start the unit.
The battery voltage/ mains output (unregulated) is available as VPRINT for printer motor driver
device. The rest of the outputs are regulated by SPIC converters LT1613. The main output is 3V3
marked as VCC. This is converted by U10 and powers the main uC and most of other devices. U8
converts to 2V5 which is required by the display driver (FPGA), and U7 converts to stable 9V required
by the backlight and the printer. U14 is a low dropout voltage regulator supplying 5V to the printer
controller.
9
Sensor Interface (Drawing 078-04)
J5 is a 6 pin RJ422 multi purpose connector. Its primary function is to connect to spirometry turbine,
but it also used for interfacing with Rint head. The power to the interface is via pin 4, which has either
continuous 9V from the mains module if connected or 9V from the regulator but can be switched on
when required. This allows the Rint head internal battery to be charged if connected to the mains, or
9V is controlled under battery operation. Pins 2 and 3 of the connector are turbine outputs or are
shared with SPI bus for Rint or other interfaces. U15 and U16 are Schmitt trigger which ensures that
the turbine pulses are clean. U13 is a latch which remembers the signal of pin 3 when pin 2 is
triggered. These determine if the flow is inwards or outwards.
In the main uC, the SPI port and the RS232 port are shared on the same I/O pins. The output in
RS232 mode also drives the internal printer or can be used for programming the printer uC. The
selection is done by analogue switches U17 – U20.
Display Driver (Drawing 078-07)
The STN 0.25 VGA colour display is entirely controlled by Altera EP1K10 FPGA. Normally, the FPGA
code is loaded via a serial EEPROM, but in this case, the uC loads the code on start-up. The code file
is loaded in the flash disk. The advantage of this method is that it allows code to be upgraded in the
field. The STN display can only generate 8 colours by mixing RGB pixels, but other shades can be
generated by time multiplexing the RGB colours. For this reason the lighter shades may generate
some interference patterns.
The display pixel information is held in 128 KByte RAM. Two display pages (A & B) are adopted, and
the software can select either to display page A or B or mix them together as A & B, A | B etc. Page B
can be horizontally and vertically scrolled by simply writing the offsets. This allows display to be
scrolled during spirometry tidal breathing test. Furthermore, the controller has a facility to flash parts
of display with programmable on/off time period and allow programmable background colours.
U33 generates 27 V (VEE) required for the display. This voltage can be adjusted by varying the digital
variable resistor U34. Modifying the value of the resistor changes the contrast of the display.
U31 is a touch screen controller, which detects if the stylus is pressed on the display and sends an
interrupt to uC. The uC then reads the A/D conversion of the touch screen X-Y resistance value to
determine the position of the stylus.
Since the display controller generates high frequency signals, care should be taken to ensure that the
cable from connector J9 to the display is properly shielded.
Sounder Circuit (Drawing 078-08)
uC generates a known frequency which is sent to the audio speaker via an audio amplifier/ driver
(U37). This method allows various musical sound to be played through the speaker. The audio
frequency is passed through digital potential divider (U35) to adjust its amplitude which acts as
volume control. The fixed up/down key varies the potential divider. When any key is pressed, the U36
mutes the sound to avoid clicking noise. The uC and also mute the sound using VOL_OFF I/O line.
USB Driver (Drawing 078-09)
Super Spiro Mk2 has facility to act as a host USB controller or as a slave USB port. The host facility is
required to drive the USB printers, and in the slave mode, it communicates with the PC to either send
the data or in case of Spida, perform live spirometry tests. Cypress SL811HST device (U39) is used
as a USB controller, running at 12 MHz for version 1.1 full speed. Resistor R79 is switched on in the
slave mode to inform the host that it is full speed, whilst in host mode, R62 is switched on to load the
D+ line via 15K resistor.
10
U40 is a 5V voltage regulator, supplying power to USB slave device. This regulator will only be
switched on if the host is not connected and the software activates the USB PWR+ line. Pin 4 of J12
is logic low if connected to the host.
