flicklib demo results in error.

[edouin]

I am getting this error when trying to run flick-demo.
Can you suggest what to do?

I checked i2cdetect and it shows the device.

Also tried firmware update.

pi@raspberrypi:/usr/src $ flick-demo

@edouin The interesting line in the traceback is:

File "build/bdist.linux-armv7l/egg/flicklib.py", line 278, in _handle_firmware_info
Exception: An invalid GestiIC Library was stored, or the last update failed

When you look at flicklib.py (https://github.com/PiSupply/Flick/blob/master/flick/flicklib.py)
it seems you were able to communicate with the Flick board, but it did not recognize the correct firmware.
Note there are specific firmwares (different parameters) for each variant (https://github.com/PiSupply/Flick/tree/master/firmware).

Right now I do not have any suggestions, except to try to reload the correct firmware.

Indeed, flashing solved the GestiIC library error.
But gesture data is still not registered by the flick-demo.py.
I am using Flick Hat and it was working before.
What can I do for troubleshooting this problem?

Update on the situation.
C++ example ./flick_example is showing the readout.
The problem seams to be in my Python code.

@edouin See my answer on Discord

Still no luck. But getting readout with this library https://github.com/open-electronics/GestIC

[edouin]

Ended up using direct I2c read write...
...
bus.write_i2c_block_data(addr, 0x10,[0x00, 0x00, 0xA2, 0x85, 0x00, 0x00, 0x00, 0x7F, 0x00, 0x00, 0x00, 0x7F, 0x00,0x00, 0x00])
...
data = bus.read_i2c_block_data(addr, 0x00, 26) #Read the sensor data payload
...

This way everything works fine.

I am having the same issue, i don't know how to solve, i've tried reinstalling the OS, i2cdetect is also good, i don't know how flashing solves the issue

Has anyone solved this problem?
