Figure 6 - Datalogging to a ???? Flash dis? with the VDrive2
By adding a ??IC ??icrocontro???r and a f?? oth?r co??pon?nt??? th? ?DRI?E2 ??od??? can b? t?rn?d into a F?a?h
dis? ?ased data logger. Fig ? shows the schematic o? this simple application. The ?C signal input is connected to
th? 10-bit ana?og?? to digita? conv?rt?r on board th? Microchip ??IC. Th? ??IC cod? tak?? a pr?-d?fin?d n???b?r of
?a??p??? and th?n ?rit?? th? corr??ponding ?SCII va???? to a co????a ??parat?d va??? (CS?) fi?? on th? ?SB fla?h

e?tended ??CII command set is designed ?or use with a terminal whilst a shortened he?adecimal version is used with
a microcontroller.
