I try to setup the PB0 for PWM mode to drive a LED.When I use the TIM3_CH3, it is working with the following code.But it does not work for TIM8_CH2N.I suppose something to do with the "N" but could not find out what in HAL code should be changed.TIM_...
I'm wondering what would be an ideal circuit to connect a very simple 2-4W class D audio amplifier to a DAC output of an STM32 MCU.My goal is to be able to play some WAV files using build-in DAC of STM32F051.I found an amplifier TDA2822G-S08-R, took ...
How to connect smte32f469 discovery kit to internet ?
I am trying to transfer sensor data collected on a NUCLEO-144 L552ZET6Q board to a Sparkfun Artemis BLE Module via UART DMA. However, I can't get the STM32 to send anything on any UART besides messages to TeraTerm using the basic HAL_UART_TRANSMIT fu...
I have been testing the ADC on my STM32L0 with 12-bit resolution and for some reason, every measurement I take has a 0.048 V offset. I've tried a different supply voltage (from 1.8 V to 3.3 V), but the offset stays there.This offset starts at the fir...
Dear ST Community,as part of a project to capture analog microphone data, I would like to use my own callback funtions instead of hal callbacks. For this I register my ADC callbacks with the HAL function HAL_ADC_RegisterCallback as follows:/*********...

I am using TIM2 on a STM32H7 to generate interrupts - e.g. every 1 ms. Using the formulas from the documentation, Update_event = TIM_CLK/((PSC + 1)*(ARR + 1)*(RCR + 1)), solving for ARR and using RCR = 0 we getARR = 1/(Update_event * (1 + PSC) / TIM_...
Hi,I use RTC on a STM32L073. Every 12hours, I receive a date and time to set to the RTC. (Sometime, like 1% of the time) After writen the new RTC value, the RTC doesn't overflow after 23h59min59sec and keep counting without incrementing day. I can ha...
About Power-Down Sequence (Device : STM32H7B0xB)Datasheet : DS13196 - Rev 6 Page 13"During the power-down phase, VDD can temporarily become lower than other supplies only if the energy provided to the microcontroller remains below 1 mJ. " Could y...
