CAN peripheral test in NUCLEO-L476RG MB1136 rev C (C-04) Board.and work with STM32CubeIDE (1.3.1) + STM32Cube_FW_L4_V1.15.1.(1) The CAN1_RX(PB8) and CAN1_TX(PB9) pins of STM32L476RG do not drop the voltage to 0 Volt. Low voltage is 1 Volt.Tested ...
I wonder how to program the UART interrupt service routine to prevent race condition.All variables used by ISR are declared with volatile.Is there any other better way to do volatile declaration to prevent race conditions ?For example, would ATOMIC_X...
The example I posted above seems to be a little different from your problem.Using the LL UART interrupt TX with the STM32L031+Example above, the operation works fine about 0.5~1 hour. However, RX ring buffer index mismatch & TX data is broken after s...
Output signals and inputs to external Tx and Rx pins do not work in the "loopback mode" & "silent mode" of the BxCAN on the STM32 MCU.CAN function worked that the STM32F103 MCU and the ST32CubeMx CAN library (with CAN normal mode).Test the STM32Cub...
As mentioned by the community member above, should review the hlpuart1->SR register to see which interrupt bit is set with JTAG.Like the code below, the ISR infinite loop does not occur when generated bits in the interrupt routine clear before functi...
