Hi dannysauer, I was going to say query the display until I read the last part of your post. Yes, the best thing to do is to query the display. Say for example, send cmd 254 55 and it should reply its module type which is 0x0F for the VK204-25 that you have. This of course is an indication that it i...

Hello dannysauer, Thank you for your post. Unfortunately there is no indication that comes out from the display to signal that it is ready for communication. The ACK that is described in the manual is referring to I2C communication protocol. You mentioned that your controller (PIC) is powered up bef...

Use the same settings: 19200,N,8,1. This is elementary testing. If this does not work, it could be the installation of the drivers.

Hi,
I just want to ask you if you have simply tested the module with hyperterminal or any other terminal emulators. Just to make sure that the module is working properly.

Hi kfaria,

Instead of sending 254 96 in Sub Akr_off(), please try sendiing 254 126 1.

Please let me know how it turns out

Hi kfaria Okay, now we know that the command is being sent. But the problem is even if it is sent, you still see repeated data coming on the RS232 lines on about 2ms apart? I just want to know how you can actually tell that the module did not follow command 254 96 (since in the original code, after ...

Hi kfaria, I do not see anything wrong with the code. Have you seen A == 3? Since this is the only branch that will actually send the command 254 96, make sure that you actually get the value 3. By the way, there is really no need to clear the keypad buffer every single time you read a keypad key. T...

Thanks for posting. I do not see any reason for the module not to follow command 254 96 and turn off auto repeat mode. Do you mind sending a piece of your code?

Hi bigred1521, On the LK202-25 borad, above the DB9 connector is the RS232 IC, and above it are 4 solder pads. From left to right, lets name the pads 1 to 4. If pads 1 and 3 are soldered, then the module is set to RS232. If the pads 2 and 4 are soldered, then it is set to TTL levels. Again, if the L...

Hello thefloyd666,

I am glad to hear that your problem has been fixed.

For the keypad problem, please try setting the debounce time. It can be done by cmd 254/85/8. 8 is the recommended value for setting debounce time that would result to 52ms.

Hello bigred1521, Thank you for your post. When connecting the BS2 Stamp to the LCD, the LCD needs to be set in TTL levels, unless there is a RS232 driver after the BS2. When the LCD is set to TTL levels, it will not work with Hyperterminal. You mentioned that you tried hard setting the LCD, I wonde...

Unfortunately, no. You will just have to declare an unsigned char array; so instead of:

char string1[] = "Hello";

you will need to have
unsigned char string1 [] = {'H', 'e', 'l', 'l', 'o', 0xFE};

to squeeze in 0xFE

Hi arney, I'm glad that you have figured out what was wrong. Just so you know, you can also communicate with the LCD2041 via TTL and with TTL you wouldn't need an RS232 converter. Please see the manual how to configure the LCD2041 to TTL levels and so you may connect the PIC directly to the LCD. If ...
