For my project I am using the LPUART on an STM32U545 and 585, currently I am using the normal GPDMA and this works like a charm in normal run mode. However I want to be in STOP1 and receive UART communication. As per the reference manual the GPDMA is...
Hello,After some investigation was found that memset has different behavior executed from different places in flash. Data and instruction cache are off! Micro used is stm32h743xi.Function is called with following arguments --> memset(dummy, 0, 64)Its...
Hi,I'm aware of the BOOT0 pin which is available on most STM32 MCUs and allows to select the device being booted from Flash.Now my problem is, once shipped to an end user, this flash can't be updated easily. So it would be better to have a more simpl...
Hi everyone,I'm working on a project using the STM32G0B0VET6 microcontroller, and I have an ILI9488 TFT display (320x480) connected via SPI. There is no external display controller – the STM32 is driving the display directly.ProblemThe display works ...
Hello community,We are designing a low-cost pump controller and are looking for an MCU with the following specifications:MCU RequirementsFlash: 512 KBRAM: 128 KBGPIOs: 64 to 84Integrated RTCRTC cell supportNo wireless connectivity neededLowest possib...
This is the output from an UPS inverter. they are driving signals of four mosfets of H-Bridge. I can generate same signals using stm32f103 advanced motor conotrol timer(TIM1). center aligned pwm and complimentary output with maximum 20us dead time.Th...
Hello,we are using the ST USB Stack in Device mode in an F413 project with a CDC Device Class (STMicroelectronics Virtual COM Port).Both HAL and USB Stack code are from ST github at https://github.com/STMicroelectronics/stm32-mw-usb-device.git and ht...
Hi, I would like to use the MDMA with the QSPI on an STM32H743 or similar.I need to use the QSPI to interface with several multiplexed LCD displays and I want to use the QSPI in 'indirect' mode to send commands to the displays and DMA the pixel data ...
Good morning, I have been trying to make simple characters appear on the 16x2 character LCD display for a while now and I am using a U575ZI-Q core board. I have followed many tutorials but none of them have allowed me to display a simple line of text...
