HAL Library 20- FATFS for STM32Fxxx 122

HAL Library 20- FATFS for STM32Fxxx

FATFS library (HAL LIB 20) is a “generic” library for all FAT related implementations, such as SDCARD, USB FLASH, SPI FLASH and also SDRAM can be used with proper FAT initialization. My FATFS library currently supports only SDCARD communication with SDIO (STM32F4xx) or SDMMC (STM32F7xx) or SPI on both families. There is no big difference between them and you can treat them as the same peripheral with only different name. In case you are interested for FATFS based on STD...

Library 21- Read SD card with FatFs on STM32F4

Finally I got it working properly. Reading SDcard was very awesome for me for first time, so I decided to make a library for STM32F4xx devices and post it to my website. It’s basically just communication interface between STM32F4 and FatFS library by Chan. It supports SPI or SDIO communication. Library also supports USB communication, but for that purpose you need USB stack too. USB is available here. Below I’m showing how to setup everything with STM32F4 to get SD...

All STM32F4 libraries 123

All STM32F4 libraries

Because there is a lot of libraries I have done, I will make a table with all of my libraries at one place. When new library will be created, it will be posted here. These libraries work on both Discovery boards, if not, it will be specified. Actually, libraries should work on STM32F4xx series of microcontrollers if they have peripherals that are need for library. All STM32F4xx MCUs don’t have everything inside. 🙂 Libraries are tested on my 4 STM32F4...
