51 / 81 page  Crystalfontz Data Sheet Release 2014-11-17 www.crystalfontz.com CFA631 Intelligent Display Modules Page 51 type: 0x16 = 2210 data_length: 2 data[0]: location code 0 = "Data" register 1 = "Control" register, RE=0 2 = "Control" register, RE=1 data[1]: data to write to the selected register The return packet will be: type: 0x40 | 0x16 = 0x56 = 8610 data_length = 0 23 (0x17): Configure Key Reporting By default, the CFA631 reports any key event to the host. This command allows the key events to be enabled or disabled on an individual basis. #define KP_UL 0x01 //(upper-left) #define KP_UR 0x02 //(upper-right) #define KP_LL 0x04 //(lower-left) #define KP_LR 0x08 //(lower-right) type: 0x17 = 2310 data_length = 2 data[0]: press mask data[1]: release mask Valid values of the mask are \000-\015. The return packet will be: type: 0x40 | 0x17 = 0x57 = 8710 data_length = 0 Configure Key Reporting is one of the items stored by the command 4 (0x04): Store Current State As Boot State (Pg. 39). 24 (0x18): Read Keypad, Polled Mode In some situations, it may be convenient for the host to poll the CFA631 for key activity. This command allows the host to detect which keys are currently pressed, which keys have been pressed since the last poll, and which keys have been released since the last poll. This command is independent of the key reporting masks set by command 23 (0x17): Configure Key Reporting (Pg. 51). All keys are always visible to this command. Typically both masks of command 23 would be set to "0" if the host is reading the keypad in polled mode. #define KP_UL 0x01 //(upper-left) #define KP_UR 0x02 //(upper-right) #define KP_LL 0x04 //(lower-left) #define KP_LR 0x08 //(lower-right) type: 0x18 = 2410 data_length = 0 |
