I'm using the stm32f429 discovery, I made a PWM control and tested it with a potentiometer and it worked as expected with 1mhz. Now I need to do the temperature control, I'm using a MAX31865 with PT100 and heating a resistance with the PWM output (th...

In the case of normal CAN, the mailboxes were full and to send more than 3, use HAL_CAN_GetTxMailboxesFreeLevel(hcan) != 3In the case of DF CAN there are no mainboxes but FIFO or Queue mode, how do I empty it in DF CAN? without using delay and of cou...

hi, I'm using a discovery stm32f429 together with the STM32CubeIDEI would like to know why when I use while to wait for the mailbox:while (HAL_CAN_GetTxMailboxesFreeLevel(&hcan1) != 3){// Wait until all transmission buffers are free}the debug does no...

I did other tests but instead of the PWM value of 1000 for 4096based on the test I did and because it blows the scaleThe PidOut variable is a float, so the maximum value of the float is: 3.402823466 E + 38 and the minimum value will be -3.402823466 E...

Reading about the HAL DF CAN library I found: HAL_FDCAN_GetTxFifoFreeLevel(hfdcan) != 3

It seems like that's right, create a global variable being the function and it didn't give that error when reading the expression

Thanks for the answer, ST could make an easier way for this
