Analog read

[nezra]

given the huzzah32 with it's battery & voltage divider attached directly to one of the analog pins; and the release the kraken patch, #34?, would it be possible to add an analog read function? and maybe a digital read?

I'd like to use the built in battery functionality of the huzzah32 to power a portion of a project; and possibly use it for supplementary IO; but i'd want to monitor the voltage. the added voltage regulator & power storage would be able to provide an easier way than making a voltage regulator tacked a feather & it's battery pin.

I don't pretend to understand the nina-fw and the command handler language; but it reminds me alot of arduino. after reading through it, would something like:

int setAnalogRead(const uint8_t command[], uint8_t response[])
{
uint8_t pin = command[4];
unit8_result = 255

result=analogRead(pin);

response[2] = 1; // number of parameters
response[3] = sizeof(result); // parameter 1 length
memcpy(&response[4], result, sizeof(result));

return 9;
}

be sufficient?

you could but yeah you'd have to add the matching capability to nina-fw as well - we don't have plans to add it but feel free to!

Your issue on NINA could be combined with arduino/nina-fw#19
That's the place to start. Once (if) it's implemented in the NINA firmware, it's straightforward to expose it from the ESP32SPI library.

PRs for #76 submitted (ESP32SPI library and NINA firmware), to provide digital and analog reads.
