LTDC prevents CPU (of my MCU) from going into sleep mode. When i deactivate the LTDC clock, the CPU goes to sleep mode. LTDC interrupt is enabled trough IOC, without enabling of LTDC interrupt, screen remains black. I use the following MCU: STM32L4P5...
Dear ForumIm using the SPI of STM32 H7 43ZI.-In master mode,full duplex, not problem: Transmit and receive data precisely, up to 2Mbit/sec (limits come from cable lenght) .Each pack is 24 bytes.-In slave mode, this is what i do (master at 200Kbit/se...
Hi,We have a customized board with STM32F103, it measures water level and sends the data to a server, and then enters into Standby mode for 1 minute after setting up a RTC alarm for wakeup. Occasionally, we see wakeup failures. This happens randomly,...
Hi I am working on a project with STM32H730IBK6Q and STM32Cube IDE 1.16I am trying to use PA0_C as a GPIO, but the GPIO function is not connecting properly. PA0 is used an ADC, not as a GPIO, so from how I understand muxing there should be no conflic...
Hello everyone,MCU in use: STM32H745XI (dual-core, Bootloader v9.1, CubeIDE 1.16.1, HAL v1.11.3, CubeProgrammer v2.17.0)Hardware status: BOOT0 HIGH works perfectly, I can access the system bootloader over USART1 (PA9/PA10), and program via UART. Hard...
Hi ST Community, I’m working on a secure boot implementation for the STM32U3 series and need to replace the factory ROM bootloader with my custom secure bootloader. Here’s what I’d like to clarify: Can We Fully Remove the Factory Bootloader?The STM32...
Hello,I am using STM32G0B1cbt6. And I am using native bootloader to update firmware. But in some boards not able to update firmware, it is giving below error:And when we replaced the MCU then bootloader started working normally. The failure percentag...
I'm trying to get the DMA engine to trigger transfers on TIM8_CH1 (DMA Request Mapping: Channel 7, Stream 2). However, it's not working. I verified that the TIM8_CC1 looked good by driving it to an alternate function output. Then, all I changed was...
Hi,I am testing the ECC on DTCM on the STM32H7A3ZI. At start of day I initialize all of DTCM apart from a single test location. I have a test which reads from that uninitialized location and successfully provokes the SRAM ECC interrupt, correctly r...
Does anyone know if the PGA OpAmp in the STM32 has the ability to interface with a differential input - like a Strain Gauge Wheatstone bridge? I'm not convinced its going to work because my signal is going to swing +/-50mV, and the OpAmp does no loo...
