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.

why use valuable ram for some of these things, we have 512k of flash memory to use, we havent even come close to filling it.

anyway reading through the data sheets, to run M/L from ram, the chip on boot has to set aside some ram to enable this, therefore taking away some ram to use as it currently is.

Howdy Terry

If we can place runtime loaded code into flash versus ram its all the better since we have availablh flash. Great idea ;-)

MMB function to write to flash could be part of the method that allows runtime loaded code. Reading and writing to flash could be useful in general to store persistent data such as calibration settings.

This flash r/w concept could be a useful addition the core MMB interpreter. The write routine could allow writing only to permissible flash areas to avoid a rogue programming bug overwriting/killing the interpreter. Maybe Don will add it to firmware wish list.

Wish 30: MMB function to write to flash could be part of the method that allows runtime loaded code.

Cheers Don...
