What's the maximum amount of current which I can draw from a NUCLEO-L476RG output pin? (in order to power a light source) Is there a limit per pin as well as an overall limit for the whole board?
It seems simpe but, it is not. How can I read CPU_TAP_ID register? I can be access only afer connecting debugger but how can it be read?
Hi All,I am interested to use STM32H7 Dual core for my project. To save component and space, May I use it without external oscillator?Thanks
A'm using LL libraty. I need simple PWM output on PB1.TIM2 init related to CH1 and PA5 work.When I change setup to CH4 and PB1 pwm doesn't go to the pin.Both PA and PB ar clocked.Under debuger I checked MODER registers, AF_5 function is selected.Work...
