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’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,...
I was trying to build a flight controller with this board. I was using rizacelik's repo for this project. At first, i was using the 3.0.1 firmware .hex file but then later wanted to switch to the newer 8.0.0 firmware so i flashed the newer .hex file ...
I have tried USB examples for Stm32F070, F401, F407 Black board and calling a single "CDC_Transmit_FS" function to print a string but none is working. The hcdc->TxState value is some garbage big value so it always stay busy and also not getting inter...
I used Cude IDE version 1.18.1. successfully then upgraded and wrote the second project (timer). I'm using Nucelo-64 STM32 F411RE with clock rate 84Mhz. My new project is to use the TIM4 with the settings: PSC: 8399, CP: 10000 to toggle the LED per ...
