t6963 not quite working #197
Comments
A couple of observations:
However, if I comment out this line entirely, the display shows nothing/does not respond at all.
This seems to confirm that the ~WR and data lines are doing something, just not what I expect.
|
Did you tie the ~RD line to +5V? Can you also sent the complete code for the text output (not just the init part). Remember to use the first/next loop. |
and
I did alter the constructor depending on whether the firstPage/nextPage or ClearBuffer/SendBuffer method was used (u8g2_Setup_t6963_240x128_1 vs u8g2_Setup_t6963_240x128_f). Both seem to give the same results. |
Hmm.. Still there could be a wiring problem (i mean, all Dx line must be connected correctly), but the DC pin should not be inverted....

Somehow I've burned out my board while testing so I'm waiting on a new one. In the meantime, a couple of questions:

Ok, solved. There were several issues:
For anybody else using the RA6963 without doing the status check, I can confirm - it seems to work fine without it. |
Great, thanks for the feedback. |
Hi,
I'm having some trouble getting this library working for a t6963 controller using a 240x128 display. I'm using a FRDM-K22F board (Arm Cortex-M4).
The LCD responds to some commands (u8g2_InitDisplay seems to clear the display) but other commands don't seem to be working. u8g2_ClearDisplay results in some garbage on the screen insteaed of clearing it:
The function u8g2_DrawStr has no visible effect.
My LCD actually has an RA6963 module built in but I believe it's equivalent to T6963. I initially tried u8x8 but it looks like u8x8 isn't compatible with the t6963 so I've switched to u8g2.
Any idea what could be going wrong here?
My initialization:
And my delay/gpio callback:
