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,I am currently facing an issue on a STM32F469NI MCU where the HAL_FLASH_PROGRAM() is succeeding yet fails to write to the flash memory.I have verified this with a basic project for the STM32F469Discovery to isolate hardware. It appears that after ...
I am having touble re-entering standby after a RTC wakup. I am using the STM32L412 (Nucleo-32)I have written some code that enables and sets the RTC, then sets alarm A and alarm B, before going into standby. After the correct time has elapsed, alar...
Dear community,I've been playing with the STM32L4R9I-Eval board and it seems that I can't drive the PG9 pin.My plan is to use the UART1 with the following pins:PB7 (rx) PG9 (tx).I checked the documentation and to use PG9 you have to:Remove R236Open S...
Hi,I am facing an odd situation when I use HAL_Delay. In most of the functions I have it works well, but in some functions the program stays in this loop forever:while((HAL_GetTick() - tickstart) < wait) {}When I debug, the difference between two val...
What is the maximum frequency for SDMMC module when 4-bit mode is used??
When the boot mode activated in STM32F427VIT6 ( BOOT0 pin to HIGH level) , the pin PE13 in strong HIGH state (really 3.3V). Why? The PE13 pin goes to LOW level just if i begin download firmware by UART bootloader

On STM32F105 chip, i need to output a pwm, then adc caputure the voltage on pwm high stable level.So i try to set tim1 ch1 to pwm out, and then set tim1 ch2 as compare output wih no pwm to trigger adc capture with DMA. (CC2<CC1)Eventrually, i cannot ...
Are there any example that uses USART as SPI ? Currently I am using stm32g071kbt6 mcu for a project and i have to use USART peripheral as SPI. Other SPI peripherals on use. I found a few presentation about USART that says USART can be use as SPI and ...
I am using STM32CubeIDE to generate a code and want to transmit two different data(voltage and temperature of battery) serially . I am able to transmit single data at a time means i am able to check voltage or temperature individually but when i am t...
