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...
Hi In my system using STM32F407, there is a period PWM signal output triggered by external comand. However we find that the phase between PWM singal edge and HSE edge is changed cycle by cycle, is F407 capable to config the phase stable?when received...
The problem is as follows, when transferring data via USART, without using DMA, the data is sent (in an attachment). When I start using DMA transfer, no data is sent (in an attachment). Maybe I am doing wrong DMA settings in the USART configurator? I...
I write code and manuals for 36 years and I've learned that those are too often written by a person who fails to put himself in the readers position. A reader who's not familiar with the topic otherwise the material was not required in the first plac...
Hello All,I am trying to send some classic CAN messages via the FDCAN3 module on STM32G474CE device. I have only pins for FDCAN3 free. My FDCAN clock is PCLK1 with a frequency of 64MHz.When I try to transmit a CAN message, firstly there is no transmi...
Hello,my problem is that i can't get access to the ADC12_CCR register. I activated the corresponding Clock in the RCC_AHB2ENR register. In addition I compare the addresses of the register from the library with the data of the reference manual, they a...

Hi .I am trying to program STM in boot mode. With controller operating on 3.3v with SPI speed less than 1.25MHz is working fine. While increase in SPI communication speed leads to get NAC not acknowledgment from STM controller in boot mode and i have...
I want to protect my code by writing OB using HALbool SetFlashReadProtection(bool state) { FLASH_OBProgramInitTypeDef OptionsBytesStruct = {0}; HAL_FLASHEx_OBGetConfig(&OptionsBytesStruct); if(state == true) { if(OptionsBytesStruct.RDP...
