Not a bug but a feature. ESP32 ECO3 added a configurable bit that will cause CAN bus speeds to be halved (i.e thus allows for lower bit rates). However, by default this feature should be disabled by the driver (see this commit ). Which version of ESP-IDF are you using? Do you have a copy of your sdk...

For some reason we have to START, then STOP, then START the CAN driver a 2nd time. We are using `can_start()` and `can_stop()`. Has anyone else experienced something like this? This is definitely not normal behavior. The CAN driver should only require one call to START the CAN driver. We have an af...

VP230 PIN 8 是用来控制 VP230 的 Sleep Mode/Standby Mode 功能。请确认你用的 VP230 板是将 PIN 8 连到 GND 禁用所有 Sleep Mode / Standby Mode 功能。

有的，里面有一个 64 byte RX FIFO。但是 RX FIFO 的操作已经会被软件驱动处理。

Should I include the "touch_pad.h" header? Yes. include by the following. #include "driver/touch_pad.h " I'm having trouble with the "touch_pad_config" function, it accepted the "touch_pad_tTOUCH_PAD_NUM0" as the first parameter but doesn't seem to accept anything as the second parameter. Your code...

A few points to consider Check that you have created the mux before it is being used (i.e. xSemaphoreCreateMutex() occurs before any call to xSemaphoreTake()). That assert you're seeing is likely due to the mux handle being NULL. What's likely happening here is that you are calling xTaskCreate() ins...

thanks for the reply.
I have tried that ( I was calling vTaskDelay() ) and it still resets...

vTaskDelay() is also a blocking function.

Don't call blocking functions (e.g. xQueueReceive()) whilst the scheduler is suspended.

I'm trying to understand the difference (if there is one) between the Free RTOS portMUX_TYPE mutex and the SemaphoreHandle_t mutex. Are they both the same thing 'under the hood'? No they are not. portMUX_TYPE is a spinlock (name is a bit confusing). Spinlocks are a form of hardware mutual exclusion...
