Subject: [Emc-users] Mesa 7i73 keypad question/issue
Hello guys,
I'm almost done with the config on the Mazak. The last thing I'm trying to
set up is the front panel keyboard. I'm using a 7i73 wich is already
working with the MPG and the lever to move the X and Z axis.
The problem I have is, I can't make the keypad input to work. In HAL I'm
always reading the 64 value . I've tried to manually short the pins of one
column and one row to see if there's any change and nothing. I'm sure I'm
missing something something here, but I didn't want to experiment without
your opinion.
I don't know If I'm forgetting to ground something, or to move a jumper.
Anyway, the P2 port of the board is working well. Please let me know what
you think.
Thanks as always!
You cannot in general use the keycode as it only reports deltas (and only for 1
servo thread period) and a no-op code of 64 when idle (no changes) so you will
miss the deltas in hal watch. Normally tye "matrix_kb" component is used to
process the deltas into a static representaion of the keypad state
