T6963C Display Driver Support

Post by edward »

Hi guys
I have problem with refreshing display rates turns slower when using font size more than 13 and even slower when more larger size , I think FLOW CODE use micro controller ram for sending fonts (If i guess right) . Is there any register selection in LCD macro or way to select LCD RAM or MICRO RAM in the FLOW CODE 8 to download fonts in LCD RAM while initializing or something else to do this and increase refresh rate in large fonts.i cant find it . may be I`m in wrong.

micro: ATMEGA2561
display: LCD 240*128 t6963c TOSHIBA.

thanks for your help :)
regards

As you mentioned v8 I have moved your post from the v6 section.
It will make it easier to get help, if you uploaded flowchart you are having an issue with.

Hello,

No way to store things in the display ram as far as I am aware.

Can you clock your ATMEGA faster, currently it's configured for 8MHz but I believe it will run up to 20MHz. This should make a big difference.

Also as you are using a port for the data pins the GLCD component property "Data Uses Port" will give you a big speed boost if you set it to Yes.

Hi,
Atmega2561 allows max 16 MHz clock frequency .
by tomorrow i`ll change crystal to 24 MHz to see whats happening .
I changed $PORT A to YES state and refresh speed got better. :D

thanks

Hi again.
maybe a stupid question but how it`s possible to print long format number on t6963 or ssd1305 displays cause in macro just allow to print max 32768 ?
Should I divide in in two parts less than and greater than with printing with $left and $right separately or there is better way?
I want to print raw ADC output of hx711 in those displays.
thanks.

Hi Ed,
You can print Long, Ulong etc by adding a string variable.
Using the ToString$ function, then sending string to your gLCD.
I have attached an example flowchart
