simone gasparella 🌡️ Get temperature from STM32 internal temperature sensor (simple library) 2 months ago
hi… thanks a lot… reading some comment from ST they suggest to calibrate the internal sensor of thje mcu. Did you do that? Thanks

Durai M Simple buzzer library for STM32 HAL 2 months ago
Im using passive buzzer, everything is ok but buzzer sound is very very low, all i hear is clock tick sound. Then i check with another pwm input, it works fine. Is there anything i have to change? Im using official Nucleo f103rb

Replying to my previous comment — it was the ADC Continuous Conversion mode. I believe this should be disabled as we want the timer to initiate each conversion.Thats what worked for me.Cheers

Great tutorial, however i am having some issues with the timer:> SYSCLK/APB1/APB2 = 25MHz> PSC = 5000-1> AutoReloadReg 25000-1> No internal clock division> Auto-Reload Preload = FALSEThis is for 5000ms ADC conversion period.It seems to wait for 5s before executing the first ADC conversion, however then ADC conversion executes continuously.Do i have to explicitly reset the timer somewhere?Why is auto-reload preload set to false? (i tried enabling this however it has the same result)
