sd card project

[kittysoman2013]

Hello, I am using a pic 16f1937 and trying to communicate with the sd card. can I use microchips fat 16 library or is it just for 18 and 24 series pics

Hi Soman

Flowcode has a FAT Component. This works very stably and it offers a lot of comfort when programming.
And if you like to use WAV file (Audiofiles) there is a anther component available : WAVPlayerFAT1

You can just drag and trop it from the component menue Data--> the component FAT(SD, SDHC) on your dashboard and try it!

regards

Stefan

The Microchip blurb suggests it doesn't allow PIC16 devices.

MDD file system library supports the 8-bit PIC18 devices as well as the 16-bit PIC24F, PIC24H, dsPIC30 and dsPIC33 devices and 32-bit PIC32 devices

The Flowcode component should be ok on a PIC16F assuming you have at least 512 Bytes of free RAM for the main SD card read/write sector buffer and a bit more for the other control variables. 16F1937 only has 512 Bytes of RAM available and so won't work. The 16F18877 may be a better option with 4Kb of RAM and should be pin compatible.
