[ 3. Hmm, 3d printer is cool. we are planning to design shield boards ... I don't think that it'l make sense to do your own shield, as RAMPS(-FD) boards are dirt cheap, and lots of people already have them. We'd need an Arduino Mega/Due compatible board, powered by an ESP32, that can replace the ex...

The hall sensor on my board (Sparkfun ESP32 Thing) seems to be fairly insensitive. I placed a really strong magnet on the chip, but th...

Hi. There are functions in librtc.a with promising names, like rtc_xtal_32k_ena, dac_out, hall_sens_read, temprature_sens_read (yes, it's actually spelled wrongly), touch_init, touch_read, rtc_smoke_detector_demo, etc. Some of them, namely hall_sense_read and temprature_sens_read are used in an exam...

BTW: Does the ESP32 support boundary scan?

Hi. I'm trying to port an application from ESP8266 to ESP32. It uses a ping library from https://github.com/dancol90/ESP8266Ping. The class definition looks like: class PingClass { public: PingClass(); bool ping(IPAddress dest, byte count = 5); bool ping(const char* host, byte count = 5); int averag...
