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...

STM32H7R/S lines: 1st STM32 with bootflash and on-the-fly encryption

The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...

Resolved! Setting peripheral clock same as the APB1 bus clock following the data sheet which is 42MHZ .It's from bit 0 to 5 on I2C control register 2.To what bit do I set it to?

In I2C slave mode, IS there any way to put a NACK token at first receive byte, when host issue block read

I implement I2C slave mode at STM32L5x series MCU, Here I have a chances to put NACK token at first receive byte(command code judged),when host issue block read command, But the ACK of first byte receive seems control by HW, Software has no chance to...

Resolved! STM32H743xG has 2 banks of 512 kByte each mapped to non-contiguous addresses, there is a 512 kByte hole between the two banks. Question: is it possible use as a single bin program file size 1Mbyte? Thanks

Resolved! stm324x9i-eval example code packs

I have bought stm324x9i-eval in the past.I need a code pack of stm324x9i-eval examples.I'm using Keil uVision5 (MDK-ARM).I really need the stm32f MCU for training, so please help.

What is the equivalent input circuit for the ADCs on the STM32F334?

Hi,I've been looking around in the documentation, and I can't find anywhere what the equivalent input circuit for the ADCs on the STM32F334 are. What is the input capacitance? What is the equivalent series resistance of the analog mux? What is the sa...

Resolved! Cannot enable Serial Wire Viewer (SWV) for printing data over USART.

I am trying to print data over USART on the stm32g030c8t6. My code is as follows:/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main...

I have a problem with EXTI. I have connected switch with EXTI pin. When the switch is pressed first time it light up the led. But when I pressed the same switch second time it does not light up the led.

void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if(GPIO_Pin == GPIO_PIN_10) { Switch10 = 1; HAL_GPIO_WritePin(GPIOB, GPIO_PIN_4, GPIO_PIN_SET); } if(GPIO_PIN == GPIO_PIN_11) { ...

I want to program a 0 to 99 counter with 7 segments but I don't know where I wrote wrong in my code.Thank you for your help.

Has RCC_AHB1Periph_BKPSRAM been replaced by RCC_AHB1ENR_BKPSRAMEN_Msk?

Legacy:RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_BKPSRAM, ENABLE);RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR, ENABLE);Current: ?RCC_AHB1PeriphClockCmd(RCC_AHB1ENR_BKPSRAMEN_Msk, ENABLE);RCC_APB1PeriphClockCmd(RCC_APB1ENR_PWREN_Msk, ENABLE);

Resolved! STM32F103 work temperation at -55C

Hi, Now we want to use STM32F103 at -55C ambient temperature, MCUdata sheet say that it work at -40C as datasheet, storage temperature is -60C. My question is that,-If MCU is powered up at -55C, what will be different with>=-40C? Such as clock not st...
