But it didn't work properly and occupied a large amount of ROM. The /flash can be LittleFS or FatFS, the SD Card can be FatFS; Files System related functions are replaced, they are used via VFS; mkfs() API is removed and is replaced by fsformat() moduqueue: queue_put() releases the GIL during operation -> REPL will work; queue_get() releases the GIL during operation -> REPL will work modusocket:. We will configure the SPI in several different modes, show how they affect the generated signal and setup the double-buffered mode to demonstrate continuous uninterrupted mode. LittleFS was updated in #6179 to use ENOTEMPTY. However when I try to start the software it fails with a GTK dependency. But this required that I convert the SDIO SD driver to non-blocking too. The FatFs module is written in compliance with ANSI C (C89) and completely separated from the disk I/O layer. 原创 电池管理未来可能的技术1.
