Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.
Hello, Micromite Explore 64, how do you use the LOAD and SAVE commands version 5.05.02, impossible to save or load a file, do you have any idea on the cpu speed settings etc, I have OPTION SDCARD 12, 14 - THANK YOU

@kiaandre,
According to the Silicon Chip article, you have the pins correct for the SD card. It does say however, that some SD cards may give problems, particularly fast or large capacity SD cards so try a few different cards.
The best way to test the cards is with the FILES command from the command prompt - this should list all the files on the SD card.
To test SAVE and LOAD, create a very simple one or twoline basic program using the built in editor, for example PRINT "Hello world"
then you can save this to the SD card with the command
SAVE "test1.bas"
If you now run the FILES command, you should see test1.bas listed.
To load a program from the SD card back into the Micromite, run the LOAD command
LOAD "test1.bas"
If you now do a LIST command from the command prompt, you will see your program
PRINT "Hello world"
shown on the screen
Re CPU speed, there are several varients of the PIC32MX470 but I think that Gogster ships the Explore 64 with 120MHz chips

PS. Do you have a copy of the Silicon Chip magazine article on the Explore 64 Micromite? Edited 2020-03-23 14:54 by panky... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it!

Yes, I ship the kits or now assembled modules with the 120MHz part. By default, the E64 or E100 start-up at 100MHz. If you want 120MHz, you will have to ask for it specifically at the command prompt with CPU 120. Most projects don't need that though, and 100MHz is usually fine.
As a test, insert SD card and issue the command FILES at the command-prompt. You should see a list of files on the SD card, assuming it has something on it.
If you get an error, report it here.Smoke makes things work. When the smoke gets out, it stops!

Hello, Micromite Explore 64, I redo several tests for the backup on the SD card that works and I can see the files on the card with the FILES command, on the other hand the LOAD command returns the error: INVALID IN A PROGRAM - THANKS FOR YOUR HEL

Hi kiaandre,
I think there is a bug with the LOAD command. You can use RUN "filename" which actually does a load and then executes the loaded program, or you can try the LOAD command with the R option (R for Run). So LOAD "filename", R which also does a load followed by executing the program just loaded. Be sure to include the comma between the filename and the R.
Cheers, Phil.

You are right, the RUN command followed by the name of the file WORKS PERFECTLY, there is surely a bug on the LOAD function, thank you
