But this was not satisfying for me. I wanted to still use the logging abilities. WXforum member Travisc came up with another solution using a PIC to fool the console that then turned itself off and enabled the logging chip once the console was happy.
|traviscs solution, very elegant|
All I needed was a way the program the chip.
I initially I started to program the chips using a buspirate in SPI mode and an SO8 ZIF socket. The security register was calculated in Excel and then flashed into the chip. This worked most of the time, but not always.
I tried in vain to write the code to use an arduino board to program the chips, JoeBean beat me to it!
It was then just a case of putting his code on to my fixture and voila, I had a fairly foolproof method of quickly programming the chips.
