I am developing custom board with STM32F207 as slave Micro Controller . The Master Controller will Fork the STM32F207 and transfer application firmware over SPI .I need complete source code for SPI Boot loader STM32F207 .
I have configured the PTP system time to update correctly (digital rollover mode), PTP_CLK == 200MHz - addend set to 0x80000000, inc set to 5ns. GPIOB5 set to output / AF11. I have set ETH_MACPPSWR to 16000 to give me an 80us pulse, but I see a 5ns r...
Hi,i tried to use the USB Device CDC Standalone example to make my MCU (STM32F407iG) working as a USB TO Serial Converter Bridge like a PL2303TA Chip. But somehow the USB FS doesn't connect to my PC. What am i doing wrong do i need to change the cloc...
HI, I just bought STMF769i-eval and started with lwip examples from the FW . but there are not working, even i can't ping. then I read about Solder brigdes and de solder some of the brigdes and try again but still unable to ping. is that hardware pro...
I have an FreeRTOS example running on STM32F429I-DISCOVERY/NUCLEO-F429ZI, which has the STM32F429ZITx MCU inside. But I wish to port this to a new MCU (STM32F429VITx). How do I do it?The main difference between the two MCUs is:ZITx version has more ...
I'm using HAL library for stm32f4 (V1.7.1) and trying to understand how HAL_I2C_Master_Transmit works. This function transmits a master to slave packet on SDA line. In the stm32f4xx_hal_i2c.c code after sending slave address there is a loop (while(hi...
Is the cdc standalone example for asynchronous uart mode or synchronous mode?
We are currently developing a portable device with a STM32F4 display and so on. It is usually powered with non-rechargeable batteries (4x AA LR6). It consumes at least 140mA and max 450mA. As everyone has a micro usb cable and power plug, we thought ...
Hi,how can i program the BRR Register in the USB Device CDC Standalone example for STM32F4xx?The Example code uses UartHandle.Init.BaudRate = 9600;How can i directly access to USART_BRR Register?
This is the snippet of the code that is showing me the error. It has been written just above the while(1) function.Also, I have attached the whole code in the attachments. FATFS myFATFS; FIL myFILE; UINT testByte; if (f_mount(&myFATFS, SDPath, 1) == ...
