Note:
Digital or analog module
LED signalization
Selection of operation mode
Press the button first and then plug the module into the USB.
uPSD software use
The program automatically detects whether a module is digital or analog.
The recognition is based on the value on pin P3.3. A digital module has this pin
unconnected which is the same as logic ‘1’ because of an internal uPSD pull-up. Analog
modules must employ a pull-down resistor to enable the detection of logic ‘0’.

Immediately after the module is plugged in, all LEDs are lit while initialization is in process.
When uPSD, the peripherals (I2C,ADC, etc) and MEMS are initialized, the LEDs are turned
off. Immediately following this, the main starts and LED7 blinks.
●
During the initialization an operation mode can be selected by pressing buttons:
●
●
●
●
LED5 (green) blinking
Data is being read. Digital modules are using I
LED6 (yellow) blinking
This indicates USB communication, data is being sent.
LED7 (red) blinking
The program is running, this led is toggled in main.
If LED7 doesn't start blinking, the initialization will have failed.

On-line measurement (default)
BUT5 is pressed
Off-line measurement (it erases the Flash for new measurements which takes around
5s for the 256KB flash)
BUT6 is pressed
Read out data from Flash (useful after the off-line measurement)
BUT7 is pressed
No effect.
Check hardware
Try to restart the PC
Re-program uPSD
If still not working, contact support
