Hello,I am currently working with STM32G431RB, and I have an SD card connector on my board. When the CPU clock is below 80MHz, everything works fine. However, when I increase the clock frequency and insert the SD card into the slot, the program crash...
We are developing a user interface by using STM32H743 + SDRAM + LTDC + DMA2D and connecting to LCD through an FPC cable, which is only 30 CM long. It works fine.But there is one problem, in some of our products, the LCD can be placed at a position th...
I'm trying to read the ID of ST7701SN with STM32F469. The read command was sent correctly by the MCU. But the voltage of the response by the ST7701SN is too low. Could it be caused by the settings of the MCU? I tried different screens but it's always...
Hello. I'm trying to get the LVGL library running on the STM32H7S78. The simple DMA2D variant (LV_USE_DRAW_DMA2D) with 16-bit color depth works perfectly, but it's not very performant. Therefore, I'm trying to get the LV_USE_NEMA_GFX variant running...
Hello,i am Interfacing a module (Radiomaster Ranger Micro) to my MCU (STM32F411) using the UART Interface, but this module has only one Hard-Pin for both TX and RX.Sending packages from the MCU to the module is working already well.Now i want to rece...
Hi All,There is any problem if VBAT powered before VDD? (VBAT is another supply that feeds from Battery with LDO ) I deep dive all the datasheet and didn't find any reminder about it.
I am not able to discover the error It should work but i do not have any pulse on PB6 CPU STM332F103C8T6 ide PlatformIO #include <Arduino.h> void setup() { RCC->APB2ENR |= RCC_APB2ENR_IOPBEN; // Enable GPIOB clock RCC->APB1ENR |= RCC_APB1E...
Hi all i used LTDC hardware inside the STM32f429 discovery board to drive an external 24 bit RGB display in 16 bit mode . full GUI is designed in LVGL library , I was able to build it and flash it. I got the output on the display but with few issues ...
Hello Experts,I am using an STM32F303VET6 MCU and developing in IAR Embedded Workbench for ARM version 9.40.2.My project compiles correctly, and debugging works perfectly when I use the I-Jet debugger.However, when I switch the debugger interface to ...
I’m working on a project with an STM32F4 microcontroller and using the I2C bus to connect multiple sensors. Everything works initially, but after some time the communication becomes unstable, returning random values or causing the I2C bus to hang. I ...
