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.

Forum Index : Microcontroller and PC projects : Chain command for sd card?

  Mixtel90 said  You might be able to save variables to a file then RUN a new program from SD. That will replace the program in RAM and clear the variables area. The new program should then load the variables from the file. That way you can save whatever variables you like, only restricted by the file space available.

Just to be clear, I have no intention of making changes in this area. You will have to work with what is there. FLASH CHAIN was included specially to allow multiple programs to access a single variable set
