Re: LK204 Not returning key release? (i2c mode, polling)

Okay now it's making sense.

I did think it odd that the "1" command was turning it "off".

Thanks for the clarification.

Re: LK204 Not returning key release? (i2c mode, polling)

Right, so 0xFE /*Command*/ 0x7E /*Set Auto Repeat*/ 0x01 /*Off*/ should have the same effect as: 0xFE /*Command*/ 0x60 /*Auto Repeat Off*/ Correct? What's bothering me is that the behavior I'm seeing is that the top command works, and turns the auto repeat off, but the bottom command does not (I don...

Re: LK204 Not returning key release? (i2c mode, polling)

Thanks for the response. I actually figured it out a couple hours ago but didn't update the post yet. Using the "Set Auto Repeat" command rather than the "Auto Repeat Mode Off" command worked. 0xFE /*Command*/ 0x7E /*Set Auto Repeat*/ 0x01 /*Off*/ So now I guess the followup ques...

LK204 Not returning key release? (i2c mode, polling)

Hi all, I started a thread last week regarding the keypad returning keypresses. The problem ended up being solved, I was not configuring correctly (protocol was not set to I2C in software). I'm now trying to program some simple key press/release code for repeating events upon holding a key. I am con...

Re: LK204 Not returning keypresses when polled

However it was NOT being set in software. That fixed the issue. 0x50 0xFE 0xA0 0x00 I was under the impression only the jumpers would need to be set. A note to anyone from Matrix, the documentation for this display could make it a bit clearer that both the jumpers need to be set as well as the softw...

LK204 Not returning keypresses when polled

Hi all, I'm working on getting a LK204-7T-1U running and while most everything is working the one issue I'm having is with polling the keypad. I am working through an I2C interface and I am sending what I believe to be the correct configuration commands. I am sending the following: (See screencap at...
