I'm using it in my CatPad project test is on a 18F4550 with I2C, USB, Serial and my shared keypad/GLCD Note shift below so b0 and b1 used for HW I2C B2 to B7 used for five keyboard rows and shared with KS0108 control except for master E pin (run off RE2 port) D0 to D7 shared as column drive of keypad and GLCD 8 bit data port. The IC programming on B7, B6 seems to work fine with keyboard/LCD connected. -- we may be sharing ports with Graphics LCD, so save & restore direction -- Shift keyscan right by 2 as B0 and B1 used for I2C EEPROM oldDriveDir = keydrive_direction oldScanDir = keyScan_direction keyscan_direction = all_input -- LSB MSB keydrive_direction = ! col1 keydrive = col1 scan1 = (keyscan >> 2) & 0x1F -- active col [1] [4] [7] [*] [r] keydrive_direction = ! col2 keydrive = col2 scan2 = (keyscan >> 2) & 0x1F -- active col [2] [5] [8] [0] [g] keydrive_direction = ! col3 keydrive = col3 scan3 = (keyscan >> 2) & 0x1F -- active col [3] [6] [9] [#] [y] keydrive_direction = ! col4 keydrive = col4 scan4 = (keyscan >> 2) & 0x1F -- active col [A] [B] [C] [D] [b] keydrive_direction = ! col5 keydrive = col5 scan5 = (keyscan >> 2) & 0x1F -- active col [^] [<] [v] [>] [e] -- You received this message because you are subscribed to the Google Groups "jallib" group.
