gLCD ILI9341 SPI

Post by peterUA »

Hello Matrix. Display gLCD ILI9341 in Flowcode environment. How to remove slowly creeping black screensaver after turning on the device. Very annoying. And how to hang the data transfer rate. On the oscilloscope it is visible that it happens very slowly. Much slower than SPI is capable of at the global frequency of 20 MHz of the chip 18F47K40

Hi Petro,

The 18F47K40 can be driven at up to 64MHz using the internal oscillator. That should hopefully give you a fair old speed boost.

Maybe the chip is not running at the speed you think it is. the good old one second flasher test can clarify and ensure you are setup correctly.
