Hello, I hope it's okay that I deflect your inquiry to lcdc forum . I tried to look into setting reading interval, and all I could find is adding an Event on every second setting. As our offices are in disarray because of the move, I could not try a display and temp sensor out for you; hopefully soo...

Hi, Thank you for trying things out. You need to make sure that when you send the command 0xFE 0x58 (clear screen command) that you are sending only 2 bytes, and not a total of 4 bytes as you see in your display: 'fe58' which is 4 bytes. Please check the printf format details of your compiler. Or, g...

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.

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?

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...

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...

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...
