Is it possible to program a 28x2 program slot from another program slot?

Hi Everyone,

I was looking at the picaxe X2 product briefing and whilst reading about program slots I began to wonder if program slot 0 could write to program slot 1,2 or 3 ? ?

If so maybe slot 0 could incorporate a wireless receiver and write to slot 2 or slot 3 then after it has written the code return to slot 1. Slot 1 then decides via the wireless receiver whether to run slot 2 or 3, or goto slot 0 and wirelessly reprogram slot 2/3

I hope this is possible and sorry if its confusing I had a bit of trouble explaining !

Cheers.

No, the volume of data is to great for the PICAXE to buffer. But you could - in theory - use an i2c EEPROM to do this.

1) Download a program to an i2c EEPROM on the wireless transmitter
2) Read/send byte by byte from the transmiitter to the PICAXE receiver, which then saves the data into a second EEPROM
3) Issue a booti2c command on the receiver to copy data from the EEPROM to the internal slot.
