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...
As mentioned above, I encountered a similar issue before when using the L0 series, and at that time, I chose to abandon hardware I2C in favor of software emulation. Now, with the STM32G431, when I use LL_I2C_HandleTransfer to configure continuous r...
I am trying to write own startup file in c++ till now everything is working but I am having issue when declaring and defining something in the global scope it's most probably related to the static constructor that cpp need but I don't know how to fix...

While older MCU needed an EXTI line enabled to allow RTC alarm to wake up the CPU from Stop, for STM32U5 both RCC->APB3SMENR (11.8.44) and RCC->SRDAMR (11.8.45) mention a requirement to allow the RTC lto wake up from Stop modes. No further explanat...
Posted on March 02, 2017 at 20:43Hi,I'm using the Waveshare Open746I-C Package B based on the STM32F746 development board with StemWin with 2 Meg SDRAM, on FreeRTOS, GT811 touch screen interface and 7 inches 1024x600 LCD.After many hours of debuggin...
Can you please suggest an about 25x35 mm LCD that will work with STM32U575 microcontroller and has a low power consumption.ThanksMichael
I want to set up error handling for my CAN messages, and I wanted to start with errors from sending messages to IDs not on the CAN bus net. However, every message I send is acknowledged. There is only stm32 chip set up on the net and the rest are cur...
"Hi,I am trying to read an ADC value from the feedback of a PWM signal generated via TIM3 PWM.TIM1 generates a PWM signal with 4 channels, including complementary channels. The CCR value updates from the Sine table using DMA.The ADC is being read whe...
hi, that's the first time a i wrote to this comunity because i'm stuck with this *** problem since one week right now, i made a custom board with stm32h750vbt6 , 4 stereo audio dac and 2 4ch audio adc, eth phy , clock gen ic and etc.. now my idea was...
Hallo,I'm using U5A9NJQ demoboard with FILEX. I have something that doesn't work, the first time I write on a file, all is correct, but if I rewrite on the same portion of the file, the writing seems to be correct, but, when reading, the content hasn...
