bluehash 1,581 Posted October 5, 2015 Share Posted October 5, 2015 Many members on 43oh have requested support for a full FAT system sdcard stack using the super-awesome Elm-Chan module. This is my attempt at it. The software still needs work. so far I have tested the basics: pwd cat filename ls Hardware: 1. The 43oh SDCard BoosterPack http://store.43oh.com/The-CardReader-SDCard-BoosterPack 2. MSP432 Launchpad https://store.ti.com/msp-exp432p401r.aspx Software: 1. Compiled with CCS 6.1.0.00104 2. MSPWare Install http://www.ti.com/tool/MSPWARE Make sure you have msp432p4xx_driverlib.lib in the root of your project or linked for the above install folder. The software has only been tested with a 32MB card. This is Fat16. Cards 2Gb or greater should work just as well. Thanks to the following software: 1. ElmChan FatFS http://www.elm-chan.org/fsw/ff/00index_e.html 2. TI TivaWare for the SDCard example http://www.ti.com/tool/sw-tm4c Code is on github. pine, L.R.A, agaelema and 3 others 6 Quote Link to post Share on other sites
USWaterRockets 57 Posted October 5, 2015 Share Posted October 5, 2015 Nice work! I wanted to try doing this myself back when the MSP432 first came out, but the SD card Boosterpack has been "Out of stock" for at least that long. Thanks for sharing the work. Quote Link to post Share on other sites

Yes.. on the order page you can select Female or Female Stacking connectors. They are fully assembled. The price is higher on the stacking connectors as it takes a lot longer for me to solder them.

Hmmm.. crazy as that may be, I have never done it without FatFS. I have written to SPI flash(chip) directly though. Here is a smal project without FatFS that might help you(not msp430) http://tinkerish.com/blog/?p=13 Quote Link to post Share on other sites

bluehash 1,581 Posted December 7, 2015 Author Share Posted December 7, 2015 Hi Dale, sorry about that. Looks like the notify me is not working. I have some coming in two weeks time. Can you place a custom order of the SDCard config. That way I'll know to send you one immediately when they arrive. store.43oh.com/custom-order @@bluehash, are there any "The CardReader- SDCard Booster" boards left?

Dale 0 Posted January 7, 2016 Share Posted January 7, 2016 One more question... ;-). I am already using a BOOSTXL-SENSHUB that uses P1.6/P1.7 for I2C. Do you have any preference (technical or just convention) for which EUSCI port to jumper the SD card to use? (on J1/2/3/4) Also, do you foresee any negative effect on maximum write speed from the jumper? Thanks, Dale Quote Link to post Share on other sites
bluehash 1,581 Posted January 7, 2016 Author Share Posted January 7, 2016 Any EUSCI port can be used as long as you make the necessary changes in software. The jumper is just a solder blob. Should be ok. I'd suggest looking at the clock line with a scope if you notice any skewing in the SPI signals. Quote Link to post Share on other sites
