Re: Problems debugging ESP32 Pico V3 in vscode/platformio/openocd

You possibly need to update your OpenOCD packages... the V3 ESP32 silicon has some small changes to the way JTAG works, and your OpenOCD doesn't seem to take that into account.

Re: Mercury API

Where does the libmercuryapi.a come from? Is it compiled from sources, or is it a binary library you do not have the sources for?

Re: Calibration of RTC on ESP32-S2

Drift in the RC oscillator can happen because of two reasons: 'intrinsic' differences in the silicon the ESP32S2 is made of, and external influences like temperature and supply voltage changes and perhaps even age of the silicon. Calibration can correct for the first reason, but not for the second o...

Re: NVS Arduino Library Wear Leveling?

... My current feeling is that wear leveling is built into the api that the library is using by default and thus I'm covered without doing anything further. I'm doing about 24 writes of integers per day, so I should be set for a while, but it'd still be dumb to keep hitting the same space every tim...

I think you will do nothing right now, because it did not support aes hw acceleration for now, based on post viewtopic.php?f=10&p=56361
Note that that list is for the ESP32-S2.

Re: Mercury API

Hard to say without looking at the API, or without knowing what file the SDK complains about... Not sure if the issue you linked has anything to do with this, by the way, it seems to be for another library on another SDK on another chip (ESP8266).

Re: esp32 design

It's the auto-reset-circuit, it's been around ever since the ESP8266 was out... the idea is that you can use both lines to reset the ESP32 and put it into flash mode. From memory, the 2 BJTs are there because some (most?) terminal programs will set these lines to both low, and without the BJTs this ...

Re: mode selector convert espNOW

Send_mode_struct is the name of the typedef, the 'blueprint' of variables of that type. You can't send that. You instantiate an actual variable, Send_Mode, later; did you mean to send that instead?

Re: touch_pad_t - is it a type of variable?

It's a simple enum, nothing special about it. From components/hal/include/hal/touch_sensor_types.h: /** Touch pad channel */ typedef enum { TOUCH_PAD_NUM0 = 0, /*!< Touch pad channel 0 is GPIO4(ESP32) */ TOUCH_PAD_NUM1, /*!< Touch pad channel 1 is GPIO0(ESP32) / GPIO1(ESP32-S2) */ TOUCH_PAD_NUM2, /*...
