Hi legendsngray,

The default baud rate is 19200. To make sure that your module is at 19200,
you can put a manual override jump: please see page 11, Figure 17 of

Btw, I am a gal.

Hello HSE, I have just tried with my code tester here and I can not reproduce your problem. Here's what I am basically doing: power up delaying: delay of about 900ms initialize: clear the screen set the contrast send the string "INIT" delay for 3 seconds // just so if in case the watchdog ...

Hi legendsngray,

'A' sent in serial (TTL) is:

0 10000010 1 (the second one you had)

Hello kfaria,

Can you please give me your email address?
Mine is rmalinis@matrixorbital.ca

Do you use both I2C and RS232 simultaneously?


Thanks.

Here's the rest: A little different representation, you can probably do the changes yourself: 'f' means 0x20 (space) for '1' 42f f3f f3f 010 this means: first line - 0x04 0x02 0x20 second line - 0x20 0x03 0x20 third line - 0x20 0x03 0x20 fourth line - 0x00 0x01 0x00 and so the rest: '2' - 405 407 3f...

Hi John, So something like the following should work for you: Create the following custom chars (this is initializing the custom chars) Use command 78 for the following: 0 - 00 00 1F 1F 1F 1F 00 00 1 - 1F 1F 1F 1F 1F 1F 00 00 2 - 00 00 1F 1F 1F 1F 1F 1F 3 - 1F 1F 1F 1F 1F 1F 1F 1F 4 - 00 00 03 0F 0F...

Hi Xtrophic, Thank you for posting on the forum. I checked the code for the LK204-24-USB, and unfortunately, it does not implement medium nor large numbers. But you are right, you should be able to do it manually. I'll try to write an app note and post it as soon as possible to help you out. Best Re...

Here's a link to the DS1820 datasheet:

I made a quick search of the commands they offer, there seems to be no adjusting or calibrating option.

Hello Jason,

You can email me at rmalinis@matrixorbital.ca.

Thank you.

Thanks. I hope it is not too much trouble.

Hi Jason,

I was hoping for something like LK204-25.. if you can post a picture, most of my questions should be answered.

Thanks

Hello Jason, Thank you for posting on the forum. Can you please tell me if your board has a crystal on? Or, can you tell me the full part number instead? Better yet, if you can post a picture of the module then you do not have to answer the first two questions. Have you tried communicating with the ...

You need to pay particular attention to the acknowledge bit (specially the NAK). This indicates if the buffer is full and therefore you will need to hold off sending data. This part of the I2C transaction is there for handshaking and is necessary to make sure that data are being received properly. T...

Hello SadE,

PK202-25 PCB 3.0 does have medium numbers.

Have you tried the suggested commands:

254 / 109 - initiliaze medium numbers
254 / 111 / <row> / <column> / <digit>

eg: 254 / 111 / 1 / 1 / 5 - this will display a '5' medium digit (2 row height by 1 col width) in col 1.

Hi SadE,

Thank you for posting on the forum.

Since you have mentioned that your uC is 5V tolerant, just pull the SDA and SCL lines to 5V. This will then pull these lines to 5V which is what the PK202 requires.
