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...

ADC stays in LOCK with polling method

I have a project where i use the HAL library to poll the ADC.Controller STM32G473VC. Cube IDE 1.9.0.During the code i call ADC_24V_getADCvalue() at different places but never in interrupt routines .Even though after a few calls HAL_ADC_ConfigChannel ...

Resolved! How to continuousely loop read few register on SPI slave device, using DMA, when dummy bytes used to generate clock must be specified ( slave register adress) ?

Master is a STM32H757, slave is a LSM6DSO ( accelero + gyro ). I have a SPI link inbetween. The "int2" pin on the LSM6 rise up when data are readable in registers.This pin is connected on EXTI2 on STM32.Register read is auto incremental on LSM6.I nee...

Storing const value to ROM

Hello, is there a way to instruct the compiler to place a const value at a specific address in flash memory? On another toolchain I was able to useconst char array1[4] = {1,2,3,4} absolute 0x9D008000; // stored at flash address 0x9D008000If not, is...

Resolved! STM32F7, ART vs ICACHE?

I'm starting with STM32F767 and cannot understand the thing about connection of the ITCM to ART. What is recommended: enable ART and flash access over TCM, or just enable ICACHE like in H7, and access code over AXIM?When flash is accessed via TCM, do...

Proper standby mode enter and exit

Hello,I am trying to properly implement the standby mode entry routine on an STM32L0 MCU. I have this exemplary minimum working example that does not work as expected:/* USER CODE BEGIN 2 */   HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_SET)...

On STM32H7, can DMA access generate an ECC error ?

Hello,I am currently working with stm32H743 processor.I wanted to know if DMA access can trigger an ECC error or only the core can generate these errors.For example if there is a ram data protected by ECC with a double bit error, would a DMA access t...

hi, we are interfacing EEPROM to STM32L496ZG Nucleo board .but AT24C256 is failing to write data. Please find attached function to write data in EEPROM.We used A0 Device address to write data in EEPROM.Kindly Reply.

int at24_HAL_WriteBytes(I2C_HandleTypeDef *hi2c,uint16_t DevAddress,uint16_t MemAddress, uint8_t *pData,uint16_t TxBufferSize){if(HAL_I2C_Mem_Write(hi2c,(uint16_t)DevAddress,(uint16_t)MemAddress,I2C_MEMADD_SIZE_8BIT,pData,(uint16_t)TxBufferSize,1000)...
