FT813 can't center my text + improving block ram writing

Post by Grailler »

Hi,

I just joined this forum and I am happy to find some fellow firmware folks! I do not believe my issues have been covered yet so here we go.

1. I am writing some text on a FT813Q using the EVE-School/Eve2_81x library, the Cmd_Text() function. This works fine.
Now when I try to center the text, this doesn't work. I pass OPT_CENTERX (=512) at the 'options' argument. Am I missing something ?

2. My second thought is to try to speed up the block ram writing (existing WriteBlockRAM() function) to 4 bytes at the time instead of byte by byte. Did some of you already try that ? I tried and it sort of works but there is some display mismatch, I am wondering if the chip can even support this.

Thanks in advance guys!
