7i73 & matrix_kb - setup help needed was created by spumco
I'm having trouble getting my keypad working and could use some guidance.
LCNC 2.9
7i76ED & 7i73
4x8 keypad, no LCD: (W5 down, W6 up, W7 down)
Encoder & no analog software mode: sserial_port_0=00xxxx
keypad is a hand-wired grid of momentary NO switches in rows and columns. No diodes or resistors.
Rows connected to 7i73 pins 7-10 (KEY4 - KEY7)
Columns connected to 7i73 pins 11-18 (KEY8 - KEY15)
Main HAL:
IO HAL
I'm not getting a response from any keypress in halshow.
Tried switching to "s" option (config=4x8s) and could see the 7i73 rows blinking in halshow, but that didn't change the lack of button response.
7i73.0.1.keycode and matrix_kb.0.keycode stay at "64" regardless of loadrt config or button presses.
Suggestions for troubleshooting?
Thx,
Ralph

You might "halscope" the keycode as the changes only last one servo thread period

There's no change to matrix.0.keycode or ...7i73.0.1.keycode in halscope.

Are you sure you have:
1. The correct jumpering for a 4x8 keypad
(W5,W6,W7 = DOWN.UP,UP)
2. You cycled power on the 7I73 after changing the jumpers
3. You are using the correct P1 pins (KEY4..7 are the row outputs for 4X8 mode and KEY8..18 are the column inputs)
I can see the change in the keycode just by setting the jumpers
and shorting P1 pins 9 and 11 (KEY6 and KEY8)

Power has been cycled multiple times since setting the jumpers.
I believe I'm using the correct pins on P1.
Rows connected to 7i73 pins 7-10 (KEY4 - KEY7)
Columns connected to 7i73 pins 11-18 (KEY8 - KEY15)
I've tested continuity in case I had some crossed wires (i.e. column shorted to a row) and there are no shorts.
When you write "...change in keycode just by shorting P1-P9 to P1-P11", do you mean in halshow or halscope?
If in halscope, can you please let me know your exact setup/settings so I can duplicate? I'm really very shaky with halscope.

Those parameters match mine.
Here's what I get on halscope when I short P1 pins 9 and 11: ( you could try the same thing, copying my halscope settings)
The keycode sequence is is 64 (idle), 208 (Keypressed) 144 (key released) 0 (all keys up)

Here's my halscope. No difference when shorting or disconnecting 9 & 11:
I see that your 7i73 is identified as 7i73.0.0.keycode, while mine is 7i73.0.1.keycode.
Have I done something wrong with the address?

The number is different because My 7I73 is connected to the first (and only)
sserial chan (0) on a 7I96S, on a 7I76E, the expansion sserial channel is
channel 1. This only affects the pin/parameter names.
Is it possible you have the pins numbers wrong?
P1 pin 9 is the 5th pin from the top outer edge of P1 and pin 11 is
6th pin from the top outer edge of P1.

I doub it, but anything is possible at this point.
I'm using 40p & 34p ribbon cables to screw terminal breakout boards. The breakout terminals are numbered 1-40 and 1-34.
I'll pull the ribbons and start checking continuity between the 7i73 pins and the BOBs and make sure the screw terminals are correct.
