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...
In Figure 1 of the reference manual RM0433 for the STM32H743 (and STM32H742, STM32H753, STM32H750) no connection between cache and DTCM-RAM exists. For all I know this is correct since the DTCM-RAM is not cachable.Table 7 on the other hand shows tha...
I am attempting to bring up a custom board using a STM32U5A9 chip. I modeled the board off of the STM32u5a9j-dk dev kit (the one with a circular screen). I've been able to get our LCD screen to work over DSI and touchGFX currently runs fine.Now I am ...

Hi Since almost 10 years I'm working with STM32F103VF microcontroller with KEIL IDE, and I don't have any problem. But yesterday I received the last batch from my PCB manufacturer, and it installs that reference STM32F103VFT6 as always, but I can't ...
Hi, I've a problem with function HAL_UART_Transmit_IT.If I call this function with global data array, there isn't a problem, but If I call it with a non global data array, I receive wrong data.This is a sample code:void SendData() { uint8_t s[10]...
Hi Team,I have configured the I2C in Master Mode and Enabled LPDMA channel 2 and 3 respectively for I2C3Tx and I2C3Rx./* I2C3 DMA Init */ /* LPDMA1_REQUEST_I2C3_TX Init */ handle_LPDMA1_Channel2.Instance = LPDMA1_Channel2; handle_LPDMA1_Channel2.I...
HelloI am running a NUCLEO-H723ZG board.User data is saved to internal flash from within the application according to the following procedure: unlock the flash, erase, program. None of the operations return errors. When monitoring the memory, everyth...
I have a project to use the STM32L496 to sample an analog pulse for processing.The sceraio as followes:Input guassain pulse will be fed to postive comparator input, the negative terminal will be set by the DAC. Once the signal above the DAC threshold...
Hello,I have been experiencing a problem with the usage of the internal ADC on my STM32L476RG Nucleo64 development board. Unfortunately I have not been able to find similar problems online or in the forums.I would like to use the highest possible sam...
