New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

RTC SubSecond does not generate an interrupt with an STM32C031. Interrupt works perfectly on calendar type alarms. I work in LSE at 32768KHz, divider 127 and 255

RTC_TimeTypeDef sTime = {0}; RTC_DateTypeDef sDate = {0}; RTC_AlarmTypeDef sAlarm = {0}; /* USER CODE BEGIN RTC_Init 1 */ /* USER CODE END RTC_Init 1 */ /** Initialize RTC Only */ hrtc.Instance = RTC; hrtc.Init.HourFormat = RTC_HOURFORMAT_24; hrtc.In...

Resolved! ADC3+DMA

I'm having trouble with my STM32h757 processor. I'm trying to sample 2000 samples using ADC3+DMA1/DMA2/BDMA, but it's not working as expected. I set up the ADC to work in continuous mode and the DMA to work in circular mode with the address increment...

STM32L4P5 PWM with DMA no GPIO output

Hey all, I'm trying to generate DMA PWM for a row of 3 Neopixels. I succeeded on a Nucleo-based L496, but translating to a L4P5 target (custom board) results in no output on the GPIO at all. I've compared the generated HAL code for both and cannot fi...
