Hi, I'm using the CM4 core to receive the data and store it in the SD card, once the FATFS only works on this core. Furthermore, I want to send this data via LoRa, but it only works on the other core (CM0Plus). How can I share this information betwee...
The stm32wb55 writes data to the sd card in real time through FATFS, and the function f_write() will take tens of ms. I want to use two buffers, one buffer to store data, and one buffer to write data to and from the sd card (can this avoid the delay ...
Hi i build an application with fatfs implementation to log data.but when the file size reach 64kB, the SD card stop responding and i can not write on it.I used standard configuration for ff_confany suggestion to resolve the problem ?thank you.
I made an acquisition board with STM32WB55rgv6. I want to save ads1299 sampling data to SD card by FATFS(via spi). But my write speed is only 1KB. Here are the measures I have tried：①Improve SPI clock②Replace faster SD card③Mybuffer is 51200BAlthough...
