HAL Library 21- Multi purpose USB library for STM32Fxxx 87

HAL Library 21- Multi purpose USB library for STM32Fxxx

This USB library is designed in a ways that can easily be used with different modes. That’s why I’ve made a single library for everything what I support now and which support I will add in future. The main purpose of library is to support USB FS and HS modes on STM32Fxxx devices at the same time, without any problems. So I designed a library, which allows users to have all these possibilities: Use both USB modes as hosts Use...

HAL Library 20- FATFS for STM32Fxxx 124

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...

All STM32 HAL libraries 101

All STM32 HAL libraries

In this section, I will write all libraries based on HAL drivers from ST. If you see this first time, make sure you read this post first about how structure of my libs looks like! License All my softwares are published under MIT license. This means that you are allow to modify, share and use my source and other stuff in personal or commercial use. If you modify source code, it has to stay under GNU GPL v3 license too. I...

FatFs library extended for SDRAM 6

FatFs library extended for SDRAM

As mentioned at the beginning of post about FATFS with SDCARD, I’ve updated library to extend support for SDRAM on STM32F429-Discovery or STM324x9-EVAL board. Low level functions have been added in library for write/read data ti SDRAM. SDRAM set up To use SDRAM with my FATFS library, you will need to include my SDRAM library, which implements low level functions for read/write in SDRAM and initialization process.¬† Next thing, you need to do, is to open defines.h configuration file and...

USB Flash drive on STM32F4 105

Library 29- USB MSC HOST for USB flash drive on STM32F4

Recently I made a library to read SD cards with FatFs by Chan. Today, I made a new library for USB MSC Host and connect both libraries together, so you can operate with USB flash drives and SD cards simultaneously with STM32F4xx device. USB MSC Host library is a separate library, to handle and do stuff with USB stack. You will also need my FatFS library for SD cards. I will go here step by step, how to configure this...

Library 21- Read SD card with FatFs on STM32F4 562

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...
