FUNCTIONAL
KK1207
Commands
command first byte inputted KK1207 after changed from "HIGH" "LOW" state. some reason "HIGH" while data commands being transmitted, serial communication initialized, data/commands being transmitted considered invalid.
COMMAND DISPLAYMODE SETTING COMMANDS
KK1207 provides display mode setting shown diagram below: stated earlier command first byte(b0 transmitted KK1207 when "LOW". However, these commands, No.3 No.6(b2 ignored, No.7 No.8(b6 given value "0". Display Mode Setting Commands determine number segments grids used (1/4 duty, segments). When these commands executed, display forcibly turned off. display command "ON" must executed order resume display. same mode setting selected, command execution take place, therefore, nothing happens. When Power turned "ON", 7-Grid, 9-Segment Mode selected.
