Re: Pantum P2502W Toner Reset Chip help
I used 100KHz, but I'm guessing it takes in a lower frequency, as a brute force Read/Write approach at that frequency fails on all cases. So I'm going to bump it down to 20KHz. I'm going to write a different brute force code for the Arduino later today. I'll provide the source for anyone else who may want to try.
If I were to take a guess, some of the open I2C addresses actually form a serial no., which the printer can then read off. This would make it harder to counterfeit.
To further the study, If the brute and the sniff doesn't do anything, I'll hook my Arduino up to the printer as a slave and log the printer's commands.
