Here's a list of steps/readings I suggest you do: 1. First thing to do is to get a development board and follow the getting started guide . This should guide you through installing all the tools required to compile and flash programs for an ESP32. At the end of the guide, you should be able to flash...
Is there any documentation for guys like me with no knowledge of ESP to use ESP-IDF and write custom programs? There's no official documentation for complete beginners to ESP-IDF, as the amount of prerequisite knowledge required to use ESP-IDF is not exactly small. Could you provide more details re...

You need to account for the fact that the bit field layout of the acceptance code and mask is different in single/dual filter mode and for STD/EXTD IDs. Please refer to the following links: https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/can.html#acceptance-filter htt...

What is the voltage range of your moisture sensor vs your ADC attenuation configuration?
D2WD 芯片也有，但是那个出厂日期我就不清楚。可以联系 firstname.lastname@example.org 查询芯片上的 Date Code (请看下图）是否有做校准。 chip_surface_marking.png 如果芯片数量不多也可以用 espefuse.py 工具直接读取芯片里的 efuse 值。 # python $IDF_PATH/components/esptool_py/esptool/espefuse.py --port COM7 adc_info 有校准的芯片 output log # python $IDF_PATH/components/esptool_py/esptool/e...
