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...
This is more a bug report, not a question.Background:I want to use OCTALSPI as QuadSPI (QSPI), esp. with VDD set to 1V8. I want to get (at least) 30 MHz SCLK working on QSPI.But I cannot go faster as 12.195 MHz, which is associated with a OCTALSPI cl...
Hi, I would like to migrate a code on STM32F271 to a chip STM32H723 while using IAR EW 8.50.xMy problem is that H723 is not in the target list for IAR EW 8.50.5I can target H723 with IAR EW 9.20 but in that way I loose compatibility with other softw...
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...
