The ESP32 IC can be picked up for $2.20 in single piece QTY. How much cheaper are you looking to go?It would be fantastic having a really cheap general purpose version of the ESP32

Re: I2C issue, CLK is off
I cannot say for sure if this is it, but try moving your i2c_cmd_link_delete(cmd); right after espRc = i2c_master_cmd_begin(I2C_NUM_1, cmd, 10/portTICK_PERIOD_MS); #include <driver/i2c.h> #include <esp_log.h> #include <freertos/FreeRTOS.h> #include <freertos/task.h> #include <stdio.h> #include "sdkc...

httpd_register_uri_handler, catch all un-registered requests
In messing with esp_http_server.h, we must register each incoming request with httpd_register_uri_handler().
Is there a way to see if there was any other request coming in that was not registered ?

Re: Building Simple OTA flash for ESP32
It looks like when you created your new project you selected CMake. That one is buggy as hell. Instead choose "GNU Make". This one works like a charm! I exclusively use Visual GDB on a daily basis with ESP32 and its just awesome. One the build is successful, you will find your .bin files in the Rele...

Re: esptool.py in 'C'
I wonder if another way would be to use the uSD card for both your micro & the ESP32. You could add a IC (there are many) that will switch an input pin from one source to another. So you could have the uSD as the source to this IC, and with one control like from your micro you could switch all uSD c...
