The pictures (even small, like 60x60) load visually slow (360ms), but when writing some complex multicolored shapes of same dimensions (60x60) it is almost instantaneous (like 30ms). May 11, 2018 · Re: Any tips on optimising, i.e. speeding up ILI9341 driver for 2.2" TFT 300x240 screen. Example projects like this: Using DMA to transfer data to SPIM of PSoC 3/5 on TX_FIFO_NOT_FULL flag. Demonstrate the concept well. The tab saying "RX output", "TX output" is probably just a misnomer, but since the DMA component is itself not holding the ... tbc coin website
