Hi all,

Could anyone point me to a tutorial on which relevent  ARM peripheral firmware library to be used for a specific usage, eg: reading an SD card?

I am currenltly working on a project using STM32F103VE. This is my first time trying with an AM processor.

I found this UM0427 from ST which explain each and every single firmware libarry function, but I need a guideline on which peripheral function to be included in the C program to enable certain ARM ability. Really appreciate it if there is a readily tutorail and guideline to refer to.

Thanks

The firmware libraries are more of a HAL (Hardware Abstraction Layer), and hides the bit level configuration of the peripherals.

To talk to an SD Card you're going to need driver layer code that sits on top of the HAL and talks to the card, and to access it at a file level you will need a file system layer to implement the FAT file system, or whatever.

Hi,

unfortunately there is no extensive tutorial, but there are a lot of examples for different applications. When you download the StandardPeripheral Libs you find and Windows Help file in the root folder stm32f10x_stdperiph_lib_um.chm This should help you Best Tom

What development enviroment are you using?

If KEIL with RL installed - take a look at RL-FlashFS.

Else look at

Anyway, as said, ST peripheral driver library has no ''high level I/O'' functions to access such devices like SD, LCD, etc...

attached are some files to interface SD card. As you are using STM32F103VE, SDIO will be better option to interface SD card.

Also as said earlier if you want to do files handling in SD card, then you also have to use a file system. EFSLor FAT_FS-ELM are some free file system available in the web. ________________ Attachments : stm32_eval_sdio_sd.c : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I0QM&d=%2Fa%2F0X0000000baV%2FnviWGu71JDGUNWxaMwJKxN3Sq7uXUMgrZpZ7yKy_8b4&asPdf=falsestm32_eval_sdio_sd.h : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I0X8&d=%2Fa%2F0X0000000baW%2F5t2A9nrHjd1UuTJrV1YqnAmv0g4ix4ZZ2ei6oNgX3jo&asPdf=false
