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...
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...

Hi. First , I'm not good at English.I am testing an example of Audio_palyback_and_recorder of STM32f4 Discovery.In the i2S setting of the microphone, hAudioInI2s.Init.AudioFreq = 2 * AudioFreq; where, AudioFreq = 16KWhy did you multiply 2?A...
Hi,I tested FMC_SDRAM_DataMemory Example of STM32F769I_EVAL.I found out that the data written to SDRAM is not correct.See below picture for your checking. I believe HAL and FMC driver in system_stm32f7xx.c is not correct. Please advise me how to ma...
The chip is STM32L486VGT6. I can use the usart wake up the stop1 mode,but I can not wake up with the irda(usart3) mode .Please help!!!#define UartHandle hirda3 void Stop_IRDA(void) { UART_WakeUpTypeDef WakeUpSelection; /* make sure that no UART tra...
Hello!i am playing with the USB HID host example generated from CubeMX -- it builds fine, runs and prints log messages till everything is initalized, and it while in the loop of freertos task, the OTG interrupt never fires -- there is no function cal...
Hey everyone,I'm not sure how this popped up, but I've found something really weird. I have a DMA setup in multibuffer mode. It fills both buffers and works perfectly in that respect. The issue comes in after the buffers are filled. Once buffer 1 is ...
I have connected a DFU device (radio transceiver) to my windows 10 pc and booted it up in the boot loader update mode. DfuSe does not detect the device. However I can communicate with this device on its assigned com port with other communications s...
Hi everyone,It's almost christmass time and I'm working on some light effects for my daughter using WS2812B chained leds. I found out, that the same code compiled with Keil works fine, but compiled with Atollic true studio, I get some "flickering" an...
Hi, I have a canopen device on my desk and I'm not able to get data from it.The problem maybe is that I'm a beginner with canopen and I'm making a mistake to build up the request package.To obtain the setpoint value, registry 3000 (0x0BB8), id device...
