Hello,With STM32F411E-DISCO, I am trying to obtain the RPM value by receiving data from the hall sensor of the BLDC motor. For this, I activated XOR On / HALL EFFECT Mode and connected the pins of the hall sensors to the relevant places.HAL_TIMEx_Hal...

I am transferring sensor data between Jetson Nano and STM32F411E-DISCO via can using 2 MCP2515. On the STM32 side, imu and encoder sensors are connected and constantly transmit data to Jetson nano via canbus.However, due to a problem that I do not fu...

Hello, I am trying to take imu and encoder data in Stm32 and transfer it from can network via mcp2515. When I try to transfer data in the encoder, it works without any problems when I apply CANSPI_Transmit in the callback function.However, CANSPI_Tr...

Hello, by connecting an mcp2515 to Stm32, I enabled it to communicate properly with other cards via the Can network. However, when a message arrives, I couldn't understand how to receive it with the INT pin and I couldn't do it. I tried connecting th...

https://forums.developer.nvidia.com/t/jetson-nano-4gb-mcp2515-can-bus-receiving-wrong-id/192810Based on the solution here, I set the spi max frequency values to 2 Mhz and the problem was solved. I thank you.

Update: Outgoing data from Jetson is transmitted with full accuracy, but there is a problem with the incoming data to Jetson. I suspect there may be a problem with the Jetson nano's MCP driver.

HAL_I2C_DeInit(&hi2c1); Calling this before (just below if) fixed it. I think there is no problem right now, thank you everyone for your efforts, I will be here if there is a problem again 
