Hello, I'm currently working on an STM32G031G8U on a custom PCB. I can't really debug the code as I don't have access to ST-Link or SWDIO/SWCLK pins.I haven't managed to set TIM1 internal clock to 128 MHz as stated in the reference manual (section 5....
That's how I would understand it. When I set the output as open drain I need an external pull-up (or pull-down) resistor. Is there a reason I SHOULD use the external resistor? If so - what does this configuration option (pull-up, pull-down) mean exac...
