Degrees symbol

Post by Avinitlarge » Tue Jun 17, 2014 7:05 am

I'm trying to display the degree's symbol. I've used lcd.print((char)178) but the symbol doesn't look like the proper symbol. I've looked through the chart but 178 seems to be the nearest or have I missed something?

Hi,

It doesn't look like you are missing anything.
What is being written to the display when you send the lcd.print((char)178)?

Could you post a image of the character being written?

Thank you

Hi,

Thank you for the image.
That is the Closest to the Degrees symbol in the font loaded into your display. You can find the Character Map in you manual here:
http://www.matrixorbital.ca/manuals/LK_Series/LK204-25/

You can also create a custom character to use as your degrees symbol.

Thank you

Hi,

You are welcome.

In the manual you can see the example for a custom character builds a C with the degrees sign with it all as one character.

Again thank you for posting to our forums.

HI,

Custom characters are store in display with the DEC values of 0 -7. As described in the manual there are 5 sets saved to memory. To use a custom character:

1. Send the "Load Custom Character" command with the bank you want (0-4)
2. Either send "Create a Custom Character" or "Saving Custom Character" with the data for the character.To create the degrees Celsius example symbol noted in the manual you would send:
254 78 "ID" 8 20 8 3 4 4 3 0 (ID needs to be a value between 0 and 7)

To save the character Send the "Saving Custom Character" command. Keep in mind if you save a custom character you will overwrite whatever the previous character that was in the address you save it to.

Thank you
