Hello,I am developing a RAM-based bootloader on STM32H5, to update my firmware application.Application and bootloader resides on different flash areas, and the bootloader code is copied into RAM at startup.[0x8000000 - 0x801FFFF] bootloader[0x8020000...
Hi everyone,I have successfully deployed the VENC_SDCARD example on the board and can see its feed on my laptop. Now, I want to record it at 480x480 resolution instead of the default 800x480 provided in the example.I have modified the buffer size, DC...
Hi,I’m experiencing issues configuring a display using a custom PCB with the STM32H747BIT MCU and LVGL for the UI. Currently, the project runs a minimal setup with only one loop calling lv_timer_handler();. At this point, my main goal is to get the s...
I am trying to run a loopback test with 2 i2c's on the same board. The onboard leds need to light up on successful transmission and reception, the problem is the leds light up when in debug mode, going line by line, but not in stand#define I2C1_ADD (...
Hello,I have been playing about with the LTDC_Paint example and have managed to produce screens using my own images.I would now like to start my own project using the STMH750B-DK incorporating the elements of the LTDC_Paint example.I am struggling t...
Hello,I’m trying to measure temperature using NTC sensors on four different ADC channels of my STM32 Nucleo‑H7 board. I could previously connect potentiometers to the same pins and get flawless ADC readings with the same code and CubeMX settings. I o...
Split from this thread as it has been solved, and this is a new question: How to access eMMC through OTG on STM32H750B-DK kit.?
Hi Team,we are currently developing a product using the STM32U5 series. In our previous version, we used the STM32U5A5VJT6Q, and for size optimization, we have migrated to the STM32U5A5QJI6Q. Both MCUs are functionally similar, and we have updated th...
hello.I am using STM32F407VGT6 chip and trying to send data to PC with USB CDC function.But in the below function, the TrySendUsbPacket() function is not executing due to queue full phenomenon.void EnqueueUsbPacket(const uint8_t* data) { uint16_t ne...
Hi there,I would like to control WS2812B LEDs with a PWM timer and DMA.There are various tutorials on this, but they have not helped me and I am now asking you. Because it requires slightly different configurations depending on the model (F3, F4, G4,...
