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...

Re: 怎么把adc的校准值烧录进efuse中?

VREF 校准只
由于 espefuse 工具没有支持烧 VREF,个人用户无法自己去烧 VREF。但是所有从2018年起生产的 ESP32-D0WD 和 ESP32-D0WDQ6 芯片都已烧了 VREF 校准值 。如果您需要量产,请联系 sales@espressif.com 或在这个链接提问哪里可以购买已烧了 VREF 校准值的芯片。

Two Point 校准只
TP 校准值可以用 espefuse 工具烧进 EFUSE BLK3。但是 TP 校准值要用户自己去量度和计算(请看量度和计算步骤)。

Re: ADC1

The 12-bit ADC has a maximum raw reading of 4095 meaning the ADC is maxed out. Change your ADC attenuation to support a larger voltage range.

Re: About remote frame sending in CAN (ISO 15785-2)

Note: sending CAN TX with the RTR setting does not work. Could you elaborate more on the specifics of the issue you're facing Is there any activity on the bus when attempting to send an RTR frame? Is the receiving node acknowledging the RTR Frame but does not transmit a Data Frame in response? Is y...
