KeilA USB drive is connected to the STM32F407VGT6.The USBH_UserProcess function is located in the FatFs library for USB drives.I wrote this code in the USBH_UserProcess function: uint8_t Array[1000]={0}; for(int i=0; i<1000;i++) { printf("%d\n", Arra...

I am using the code from this post to connect STM32F407 to ili9341 display TFT_DC_SET(); Enables recording of data to the display.The speed for transferring data to the display is very important, so I need continuous data transfer. The SPI_SR_BSY bi...

I'm using SPI on STM32F407VGT6 This is the code I use to check the state of the SPI_SR_RXNE bit:This is the code for the LIS3DSH accelerometer, when I send data to the accelerometer in response the accelerometer sends data to the Microcontroller.This...

The LIS3DSH accelerometer is located on the STM32F407VGT6.I need to get the WHO_AM_I value from the LIS3DSH accelerometer register using CMSIS and SPI.The SPI1->DR register is 8 bit.I need to send the WHO_AM_I address and 8 more bits, a total of 16 b...

I created the same function with a "for" loop and a large local array in main.c.In the main.c file this function works without problems.

uint32_t byte;32 bits== 4 bytesNo, of course not, I didn't think so. The variable name is probably just wrong.If I thought so, I wouldn't shift the bits in the "byte" variableSPI1->DR = byte>>24;I only needed one byte from the "byte" variable, so I c...

I almost succeeded, but for some reason the image is of poor quality and upside down.When I sent the converted array to the display, the image was not upside down.The image is 128x160 in size, so in the for loop (128*160)/2The coordinates were entere...

>>The images will be an array of actual bytes, not hex encodings in ASCIIOk, sorry, I understand.I'll try now

I tried, it doesn't work. Maybe I'm opening the image incorrectly? I opened the text file like this: f_open(&USBHFile, "image.txt", FA_READ); I tried to open the image like this: f_open(&USBHFile, "5_16.bmp", FA_READ); Maybe this is wrong?
