LCD_DE is denoted "Not data enable". This means active low, right?

Using STM32H743VIT. Plane to use a RGB666 640x480x3 TFT. Configurating IOs using CubeMX version 4.27.0. First of all, when expanding LTDC pheripheral I only find two out of 8 possible modes, i.e. RGB666 and RGB 565. The RGB888 and ARGB' variants etc....

STM32F4 w/ SPL, Dual USB, FS as OTG, , HS(In FS Mode) as Host.

Hello everybody,I read everything I found, and it's still not clear.First, I've got my OTG_FS_Core in OTG mode with ID line.I don't need High Speed USB.Q1: Is there 2 dedicated FS Phy, (one for each Core, FS and HS)?Q2: How can I get the OTG_HS_Core ...

STM32LO Convert multiple ADCs using DMA

I'm trying to convert 3 ADC channels using DMA. But the variables don't seem to change when I watch them in the debugger. I know the conversion complete callback is executed because I breakpointed it. So this suggests that the DMA transfer is not exe...

Regulator LD39050PU33R for Nucleo Boards doesn't work.

Posted on April 13, 2018 at 01:38I have built a custom STM32F446ZE board and I used the ST890CDR current protector and the LD39050PU33R voltage regulator in exactly the same way they are implemented in the Nucleo Board from ST. The only difference i...

Why does my USBH_FATFS_FREETOS program work with one board and does not work with the other?

Hi, I'm using 2 STM32F7-SOMs and the same program for both of them. I have ran my program on the original STM32F7-SOM, and the USB host was working. Then, I ran it on the other STM32F7-SOM, and the USB stucks at enumeration state. Any suggestions or...

Is it possible to have SD and USB together on the same chip?

I have been able to implement individually:SD + FreeRTOS + FATFS + DMAUSB + FreeRTOS + FATFSI want to know how can I make (SD + USB + FreeRTOS + FATFS + DMA) work. Example would be great. Thank you every much.

Why does not work UART3 RX interrupt?

#define RXBUFFERSIZE 2 uint8_t aRxBuffer[RXBUFFERSIZE];static void MX_USART3_UART_Init(void) {   __HAL_RCC_USART3_CLK_ENABLE(); huart3.Instance = USART3; huart3.Init.BaudRate = 115200; huart3.Init.WordLength = UART_WORDLENGTH_8B; huart3.In...
