Posted on September 18, 2017 at 12:33 While generating STM32H743 project by CubeMX, I noticed that FDCAN1 can be either 'master mode' or 'full-duplex mode', and they map to different pairs of signal pins ( FDCAN1_TX/RX and FDCAN1_TXFD/RXFD ). ...

Posted on August 17, 2017 at 13:48Hello, I tried the example 'FDCAN_Com_polling' on STM32H743I-EVAL, it worked like it should be.Then I separated the example code into TX part and RX part, made one of my STM32H743I-EVAL board as TX and another as...
Posted on September 19, 2017 at 03:30 I was already using STM32CubeMX 4.22.1 and STM32Cube FW_H7 V1.1.0.The CubeMX suggested me using PH15 and PI0 but did not generate any setting for those GPIOs.So I added some code and set those GPIOs as ''Alte...
Posted on August 18, 2017 at 04:03It turns out that the FDCAN_CCCR_TEST bit was set and never been cleared.It seems that once the FDCAN is initialized into LoopBack mode, the FDCAN_CCCR_TEST bit is set and no HAL api can clear it. Not even after th...
Posted on August 17, 2017 at 16:21Hi Amel, Each board runs the example can send out frames correctly (I can see the waveform on scope) and receive the loop back frame.But neither of them can receive frames from the other.I'm assuming the loop back ...
