@robert-hh I completely agree with you but I do not see any other reason.

@Wolli01 The break in your code should simply cause an error while parsing: SyntaxError: 'break' outside loop

@robert-hh Ok thanks for that. Glad to perhaps make a small contribution to an improvement to the code :-)

@Jonno That conversion is the heart of the adc.voltage() code. But consider that the adc.value() will return 0 for any input voltage below ~60mV. So if you read 0, you only know that it's below 60mV. And Vref is slightly different for each device.

I got a resolution on this. The 3.1 Expansion board is bricked after the firmware update triggered the bug in the faulty A2 microcontroller. A replacement Expansion board is on the way. NOTE: I was able to program my WiPy 3.0 using a USB-serial adapter instead.

@MicroPyStudent appimg.bin is the only file, that is accepted. The version must not be r1.20.xx, because that has a different partition layout.

@rskoniec Thank you very much

@robert-hh I pulled it High externally and now it works. Thank you very much! Really appreciate your help.

@robert-hh Thanks. That version worked perfectly and the simple OTA script from the earlier post worked great too!

I've made some steps. Code looks now like : def cam_spi_write_register(addrs, value, spi, cs): mask = b'\x80' addres = bytes([mask[0] | addrs[0]]) cs.value(0) spi.write(addres[0]) machin spi.write(value[0]) cs.value(1) def cam_spi_read_single(addrs, spi, cs): cs.value(0) spi.write(addrs[0]) buf = spi.read(1) cs.value(1) print(buf) return(buf) but it still don't work. I made it working for a while but i forgot to push it on my repo and all code is lost...

@mac_ha The WiPy 1.3 is quite different from the WiPy 2 or 3. As far as I understand it, it does not even use the same CPU (CC3200 on the WiPy 1.x, ESP32 on the Wipy 2 or 3). I'm not sure it would be easy to port that code to the WiPy 1.3.

Any progress here? What was your method of making your web app? I would like to do something similar. Not sure where to start but I was thinking about MicroWebSrv. Is that what you used?
