There is a 5.6V peak on the rising edge using STM32F103 TIM1 PWM output pin
Posted on June 15, 2017 at 08:18Hi everybody!Recently I found a strange phenomenon that there was a peak on the rising edge when I using the TIM1's 4 chanels to be PWM output mode.And the maxium peak voltage can reach to 5.6V measured by the oscillo...
Cancel a pending UART recieve
Posted on January 16, 2017 at 23:02If i start an UART receive with an interrupt looking for the next inbound byte/char;HAL_UART_Receive_IT(&huart1, &UART1_Data, 1);how can i cancel the receive before receiving the next byte/char?
