OLED pixels (H & W) Issue
Hi,I am using STM32F303CBT6 MCU and WEO004864AWPP3N00000 OLED.Problem :Imagine, the black color shape is an actual OLED display, If I am showing something in the display. It is shown in the red color shapes. Once I scroll the display, only I can see ...
Resolved! STM32H743, ADC_CAL flag is not cleared
Hello.I try to use ADC with STM32H743II. The problem is that the calibration flag is not reset.//ADC1 RCC->AHB1ENR |= RCC_AHB1ENR_ADC12EN; //Exit DEEP Sleep ADC1->CR = 0; while(ADC1->CR != 0) { ADC1->CR = 0; }; //Enable LDO ADC1->CR = ADC_CR_A...

4bit SDIO not working, but 1bit SDIO working fine.
I use CMSIS to write program that transfer data from SD card through SDIO. For my task i need 4bit mode, but it isn't working. When i try to read some block from SD card STBITERR bit in SDIO_STA register goes high, that means that start bit hasn't be...
[STM32H745XI] - Crystal oscillator failure
There is a problem with the start-up of both HF (25MHz) and RTC(32k) oscillators after a turn-OFF followed by immediate turn-ON (cca couple ms).Oscillators:EPSON FA-238 EPSON FA-135The RTC crystal does not start-up at all and the HF one does show ins...
Problem with GPIO Interrupts and RTOS STM32H753
Hello,I am using an STM32H753 mcu and I working on a project with 8 GPIO Interrupt Pins. I am using RTX RTOS. The problem is that when the interrupt happens the same time with a thread activation. The mcu goes in dummy handler with bus Precision erro...
When STM32G070RB SPI is received, both MOSI and MISO have returned data. The data is the same through the logic analyzer.
This is my test program：uint8_t dev_test=0x00;while(1){HAL_GPIO_WritePin(DW_NSS_GPIO_Port, DW_NSS_Pin, GPIO_PIN_RESET);HAL_SPI_Transmit(&hspi1,&dev_test,1,10);HAL_SPI_Receive(&hspi1,test_R,4,10);HAL_GPIO_WritePin(DW_NSS_GPIO_Port, DW_NSS_Pin, GPIO_PI...
