wow² ;) you are really speedy!
you are right - i was missing the half word operations
E.asm seems to be available in the editor window only. when used in modules, it does not work. is there an easy way to have E.asm for modules, too?
my SPI DMA driver has a very strange issue open (marked as i#2). it applies only to the writeInterlaced( buf, N) call - e.g. when repeating the buffer. in this case, the display shows just random data for the last chunk sent. when adding a dummy chunk (just 1 pixel) at the end, it works fine (but for the price, that the function has to wait until everything sent). behaviour occurs independent of SPIx, byte count, baudrate. the only thing i saw was that writing to a certain JSVar while having the DMA running in background seems to change to DMA data. but when checking the DMA it pointed definitiely not to the JSVar... very strange... in fact, i could not figure out whats the real reason. do you use the DMA in the firmware? do you have any experience with DMA in FIFO mode + repeating source data ?
