Hello dear forum,
I am using F103RC to drive 2 DC motors
Thats why I need to use both TIM1 and TIM8
However TIM1_CH2 is at the same pin as the USART1_TX
I dont use and init USART1_TX pin becouse I only use RX input of USART1 during runtime
I initialize serial port 1 before TIMers
However I noticed that TIM1_CH2 doesnot produce PWM signal and is always at 2.6 V level
I suspect that USART1 is preventing TIM1_CH2 from producing PWM becouse
when I dont init USART1 there is PWM signal
Am I right ? why is that so ?
Can I not only use RX pin (A10) for USART while using A9 port for PWM ?
