I'm programming an STM32L4R9 through SPI according to the AN4286 application note.The problem I have is that after a global mass erase command (0x44) it won't let me execute the read memory (0x11) or the write memory (0x31), even if I wait several se...
This should be possible, in the code which moves data from the ETH controller's buffers to LWIP's buffers.I am aware of the BFD bit of ETH_MACFFR solution, which works, but it makes the box useless unless it is addressed by MAC# directly. The broadca...
I am trying to configure my STM32H743ZI2 to work with a microSD card. For data logging purposes. schematic of the SD card adaptor:I configured the following in CUBEMX:SDMMC1 as SD 4 bits Wide bus with SDMMC1 global interrupt enabled (all other settin...
Hi all!I'm working with an STMF401CC chip, and all tools up to date as of today.Code generation calls above mentioned function in SystemClock_Config() in main.c.In stm32f4xxhal_pwr_ex.c this function clearly is not available for STM32F401 devices, bu...
i had I2S 16bit out in slave mode running, but with 32bit data no success. always wrong byte order. so i try SAI , slave mode, 32bit data. but nothing coming from SAI....check with DSO.also DMA -> callbacks for half + full buffer never triggered.i do...
I am using STM32L151C6U6A device, both UART ports are used as RS485 ports. I am trying to boot from system memory and talk to bootloader using a USB-RS485 converter from my PC. Access to Boot0 pin is not possible in my hardware. So I am jumping from ...
I want to configure one STM32F091RCT6 as master and 2nd as slave.I have used Cubemx to generate code.In Master I use HAL_StatusTypeDef HAL_SMBUS_Master_Transmit_IT(SMBUS_HandleTypeDef *hsmbus, uint16_t DevAddress, uint8_t *pData, uint16_t Size, uint3...
Hi,I am developing an application with one configuration descriptor & 2 interfaces with 2 endpoints each. The endpoint (CUSTOM_HID) that comes as default while setting up the project via cubeIDE seems to be working alright. I can send and receive dat...
We have custom board based on STM32h745XIH6. We have configured our board to be in USB device mode operating in USB_OTG_HS (480 mbps) and registered it as Mass Storage device. The device is getting discovered as "USB mass storage device" on PC. We ha...
Title edited - please don't put the whole question in the title!I have created custom game controller using usb hid device. Now I want send data to device to host. Can any one help me ??
