Bug: Analog read is defined incorrectly for pins #7

Closed sjfaustino closed 4 years ago

sjfaustino commented 4 years ago

When you select a "Input mode" (should it not be "I/O mode"?), you can select Analog from the list for pins which do not have that function and it doesn't show for pins that DO have the function. I' ve compiled a list from https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/adc.html that might help: `adc1 ch0 - Pin 32 adc1 ch1 - Pin 33 adc1 ch2 - Pin 34 adc1 ch3 - Pin 35 adc1 ch4 - Pin 36 - Conflict with HALL sensor adc1 ch5 - Pin 37 adc1 ch6 - Pin 38 adc1 ch7 - Pin 39 - Conflict with HALL sensor

Very nice, I'll add that asap. Thanks

Ok... So another mistake from misunderstanding some documentations. I should not have call this "analog" but "Led Control" or maybe "PWM". Nothing to do with ADC... Sorry about that. I'll rename it. ADC looks pretty easy to implement with the arduino IDE though, at least with basic features. That's something I could do, but I think I'll finish off first the implementation of the I2C protocol, for the moment it's only possible to scan addresses. I'd like to be able at least to send data on specific registers.

This issue has been addressed in the version 0.4 of ESPecial: 51b78ee887c1c82acb9e61fc87d3daebe25bde79 Important note: as ESPecial is mainly running on wifi, because of that, ADC2 won't work. So only gpios from 32 to 39 will be able to read analog input. Check expressif documentation on that point: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/adc.html
