Re: GLK19264a handshake bug ?

It should not matter the size etc. Just always write 3 extra bytes and every now and then it will quickly follow the 0xFE with an 0xFF. But since you asked I am bursting approx 2500 bytes once a second. The normal handshake induced 'pause' is 10ms the second screenshot shows the bug induced 'pause' ...

On power up here is what I write out first... dispTxBuf[dispTxHdPtr++] = 254; // command dispTxBuf[...

So even after we receive the software handshake indicating your buffer is full a few extra bytes go out. Normally yo...

can the GPO be remapped?

But i have one display that was used early in my code development that saw lots of garbage characters and now 2 of the 3 LEDs do not respond properly...
