Hi, Thank you for posting on the forum. Instead of SEROUT2 PORTA.2,32800,[254,106,1,64,1,191,63] Try SEROUT2 PORTA.2,32800,[254,106,1,64,1,192,63] As stated in the manual (I based it on a GLK24064 manual): "The definition of x must lie on byte boundaries. That is, x must be defined as 0x00, 0x08, 0x...

Hello duck,

Thank you for posting on the forum.

TTL levels for the LK204-7T-1U-LV is 0 - 3.3V.
You do not need level translator since you will be using same voltage levels.

Thank you,

Hi Ryan, Troy has good suggestions in his last post. Pleas give them a try. Also, if you want to keep things simple to start, try reading the display without pressing any keys, you should receive 0x00 as a reply. This then is in conflict with the other keys you set as 0x00. Unless those combination ...

Hi Heather,

For the LK204-7T-1U-USB, you should get 0x2C for when you send the command 254 / 55. When you send the command 254 / 54 , you should get 0x50.

I have a feeling you are not reading from the display correctly. How are you communicating with the display, via a PC or a microcontroller?

Hi Heather, I have more questions: 1. Are you able to send characters correctly? 2. Are you able to clear the screen (cmd 254 / 88 )? 3. When you send the Read Module Type cmd 254 / 55, you should get 0x2B for the LK204-7T-1U display that you have; but it seems you said you are getting 0xB5? Try thi...

Hi Heather, I forgot the lock settings you mentioned on your second post. Please send the following to the display to unlock all settings: /254 / 203 / 245 /160 /0 / - this command unlocks all settings on the display Cycle the power on the display. Then re-try the "test012301230123" write to custome...

Hello Heather, Thank you for posting on the forum. Are you able to successfully read back from the display? If you are to send the display the Read Module Type command (254 / 55), you should receive the value '0x2B' for the LK204-7T-1U module type. As per 'command lock' can you please send me the ex...

Hi, Sorry, with the current firmware, there is no way to read the cursor position, or the char pointed by the cursor. What I can suggest is to make sure that your code will save the data it displays on the screen. For eg. when the user changes the digits of the IP address via the keypad, make your c...

Hi Elle,
Was it the delay or was it the command 0xFE 0x60 that helped?

Hello, Thank you for posting on the forum. 1) will is it possible to read a character from the lcd where cursor is pointing?. No, you can not read from the display the cursor location. You will need to have a counter in your code that will hold the cursor position value as you write on the display. ...

Can you please try sending the Set Auto Repeat Off command (0xFE 0x60) at the beginning of the code? This will make sure that any key up or prolonged presses will not be reported. Also, the delay idea is good although I am not aware of the need. But it sure won't hurt (for now) to add in a delay jus...

I see that command 0xFE 0x45 is only being sent when Keypressed is 0x48, maybe you want to change that to send 0xFE 0x45 outside that if (Keypressed== 0x48) and send it when Keypressed is not 0x00?

my goal is to read entered key once and run some commands and clear the buffer for the next run of the loop If you do this, KeyPressed will remain to be whatever it was last read. So you need to be sending the 0xFE 0x26 Poll keypress command again and KeyPressed should then be 0x00 value. Ie. make ...
