I'm curious about the delay time between the title mentioned, I toggled an IO when I wrote data into UART->DR, the delay time varies from 3 micro seconds to 10x micro secondsint main(void) { /* initial code generated by STMCubeMX */ HAL_Init(); S...
I'm writing a throw-catch case of 2 chips, the Host throws an message onto UART1 bus, then the Slave catches and shows message on UART2 for debugging, there are a delay between catch and throw, but the delay time is not always the same, in my opinion...
I'm trying to transmit a newer data while the previous transmit interrupt hasn't finished, I simply just call HAL_UART_Transmit_IT again and the result is the first called interrupt will finish its whole job and the second call do nothing, I know the...
HiI'm doing a project to detect collision on UART, when I get data from Rx, I will compare it with the data I transmitted, if there aren't the same, means collision occurred, then I will immediately stop my transmitting interrupt to stop sources wast...
Hi​I'm doing a topic to detect the collision on RS485. Since I wish to stop transmitting when collision occurred, I need to know how's the bus look like, however while transmitting, the transmit enable pin pull high on SP485EEN, lead the receiving p...
