In order to evaluate emWin graphics library, I'm using the evaluation board STM32H745I-DISCO and I'm trying the example project "STemWin_HelloWorld".When I call GUI_DispStringAt ("hello",0,0) I see that the string is not displayed from X = 0 position...
Hello,I tried to use the factory DFU bootloader to program an image via USB. Everything works until the DFU utility tries to write/erase anything in Bank 2 of the Flash (from 0x8100000). When I try to write data to this region, the DFU utility just p...
Hi, i noticed, that the LL driver does not set the RX fifo threshold levels according to the datasheet:" Rx buffer not empty (RXNE) The RXNE flag is set depending on the FRXTH bit value in the SPIx_CR2 register: • If FRXTH is set, RXNE g...
HI All, I am using STM32 nucleo-L4A6ZG development board.And I am implementing FreeRTOS MPU application with help of NUCLEO-L476RG FreeRTOS_MPU example code.I have replaced ARM_CM4F with ARM_CM4_MPU. Added mpu_wrappers.c file in my current project...
Hi,I'm trying STM32L05x embedded bootloader - Read Memory command via UART.I can read flash memory (e.g. address start by 0x0800_0000), but when I try to read SRAM ( start by 0x2000_0000) , it always return NACK.Is it not possible to read SRAM via bo...
I have my Nucleo l152RE board i want send and receive small data using vpc , then i use cdc configuration then my program : MX_GPIO_Init(); MX_USART2_UART_Init(); MX_USB_DEVICE_Init(); /* USER CODE BEGIN 2 */ /* USER CODE END 2 */ /* Infinite loop */...
For now, all the information I got about this library is it only supports to F4. So, will it work with F7 ? Thanks.
I Developed a hardware USB HS Application with STM32H750+USB3300, and just run the softerware generated by CubeMX. I make sure that the device is enumed successful by capturing the packets with wireshark. but it still show me an fail icon(an yellow ...
Hey, I'm using a STM32H743ZI. I'm trying to implement a callback function in my code but when I implement the IRQ_handler, the USB_CDC_FS stops working - when I remove the IRQ handler it works just fine.The computer recognizes the USB port but I can'...
HiI am using the Nucleo STM32F746 and have a problem with in-circuit flash programming. The flash drivers used have been in various other STM32 M3, M4 and M7 parts without any issues (since about 2010) but with the F746 the effect that I see is that...
