Waveplayer software#
The Digital Wave Player software supports the renaming of audio files and the creation of custom folders for archiving files. More information on the proper use of the TRM can be found on theĭigital Wave Player software enables the downloading of audio files to a computer, where they can be managed and archived. Based on this, I always to make sure to mount the SD Card before using any other device on the shared SPI Bus.Technologies must be operated and maintained in accordance with Federal and Department security and In summary I found FatFS to be pretty easy to use and had it wired up to my original working application in less than a day.Įdit: I should note also that I found some chatter on the web about having the SD Card share SPI with other devices - in this case it has been reported that accessing the other devices first, before initializing the SD Card can result in SD Card communication problems later on.
Waveplayer code#
At this point I was able to drop in the latest FatFs code from the original website () and that just worked in a few minutes. I didn't port the timeout timers (so they never timeout, but if everything works, you never timeout anyway - use at your own risk). 7/fatfs-for-pic32mxmz/I studied this example and ported the SPI calls (what few there were) with PLIB_SPI commands. So I don't really understand how anyone got that compiling either because it said it works with PIC24.įWIW - Here is how I got FsFat workig on my PIC32MZ (As much RAM as a IBM PC-XT!) I found this application note and code - this code uses FsFat and register access to control the SPI and it uses a timer for timeout. But it uses some #use compiler pre-processor stuff that I've never heard of or seen defined in C/C++ code. I tried using some external sd library ().
Waveplayer how to#
I'm not sure how to reconfigure this project to work with my MX250 and my custom circuitry. So, if I take the Audio Player demos and change the dev board to custom and the PIC to my MX250, it runs into some compiler errors. Although I have seen people do audio players on super old PIC's, so its kind of sad if the harmony libraries are bloated that much that I can't get an an sd card /audio player working out of the box :( :( I guess this is due to the MX220 not having enough RAM (8KB). I noticed a lot of FAT32 libraries say they can't allocate bytes for functions. I was looking at the Audio_Player samples tutorials that I found online, but they are configured for a specific PIC and specific demo board.
