Re: Need sample code for ILI9488 LCD on SPI Interface

Have you checked ILI9488 based LCD using SPI Master Example? Let me know once you check and get success into it. I'm working on it, but I don't have much free time at the moment. Apart from different init sequence, ILI9488 require 3 byte per color pixel... You can look at some Arduino library and t...

Re: Bug in spi-master READ

It looks like there is serious bug in spi-master receive when DMA is used. I was testing it with ILI9341 display with application based on spi-master example (the example itself works ok). I've added the function to read line of data from display. Display data format (when read) is: dummy_byte [R_b...

Re: Need sample code for ILI9488 LCD on SPI Interface

Looking here: http://www.instructables.com/id/Arduino-and-35-Inch-320x480-TFT-LCD-ILI9488-SPI-In/ It would appear that the ILI9488 is close to the ILI9341. Looks like you could just about follow this instructables tutorial mapping from Arduino to ESP32. Hi, Thanks for quick reply. First of all, I h...

Re: Need sample code for ILI9488 LCD on SPI Interface

Anyone has any update on this? I have one ILI9488 based LCD Display module and will test it this weekend or early next week... Hi, But for that, do you have sample code to start development for ILI9488 LCD as I have checked into spi_master code and found sample code for ILI9341 LCD which is differe...
