I just bought a TI-84 and it has the CBL data logging program. Does anyone know how the CBL peripherals communicate with the calc? ie. what is the protocol. The reason I ask is I would like to build a CBL device instead of buying one. It would work with my accelerometer project. I just cannot find any info about CBL.
The TI's proccessor is a Zilog Z80, and since the port used for CBL has only at most 4 connections(not quite sure cause I don't have a cbl cable yet) I'm guessing it uses some sort of serial interface.
