Re: Working with ESP-IDF

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...

Re: Working with ESP-IDF

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...

Re: Computer not detecting ESP 32

Which development board are you using (i.e. is it an official Espressif board or a third party one? If it's third part, any information such as a board schematic or a link would be helpful), and which USB to UART chip does it have (e.g. FT2232 or CP2102)?

Re: Computer not detecting ESP 32

If you open your device manager, does it detect the USB connection at all? (i.e. does something show up under "Other Devices"?)

Re: Blinking Program Not Compiling

That's because you're referencing blinking_task before it's been declared or defined. Either forward declare it or put the definition of blinking_task before (i.e. above) your app_main.

Re: ESP32 CAN acceptance filter

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...

Re: CAN interface?

Is there a reason why you can't use the CAN driver directly? The driver should already help route all relevant CAN signals to the GPIOs of your choosing when configuring the driver.

Re: Same values whether I dip the moisture sensor in water or not

What is the voltage range of your moisture sensor vs your ADC attenuation configuration?

Re: 怎么把adc的校准值烧录进efuse中?

D2WD 芯片也有,但是那个出厂日期我就不清楚。可以联系 sales@espressif.com 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...
