Parallel is always going to be faster. The SPI library defaults to mode 0. Jan 6, 2021 · My questions are about the code structure of either the Arduino SPI library and ILI9488 library that use SPI but has speed conditions that I want to understand as in #10. 0 framework and integrates LVGL (Light and Versatile Graphics Library) for GUI rendering. SPI speed set to 40Mhz. This circuit connects an ESP32-S3 microcontroller to an ILI9488 TFT LCD display for graphical output. (Using the HSPI bus at 80MHz is obviously a good idea here) Sep 6, 2016 · ILI9341 can work with spi clock up to 40MHz (tested for 8h working without errors). I have made some heavy modifications, as the typical Adafruit TFT libraries are designed to work with 16bit color (RGB565), and the ILI9488 can only do 24bit To change this to other GPIO/SPI devices or to other pins, you need to set accordingly values of macros ILI9488_SPI_DEVICE_ID, ILI9488_GPIO_DEVICE_ID, ILI9488_RST_PIN and ILI9488_DC_PIN, which are defined at the beginning of main. system Closed May 9, 2021, 11:46am Sep 23, 2022 · 480x320 TFT w/ ILI9488. A typical use case is variable length SPI packets where the first spi transaction reads the length and the second spi transaction reads length bytes. #define ILI9488_DRIVER #define TFT_MISO 19 #define TFT_MOSI 26 #define TFT_SCLK 18 #define TFT_CS 15 // Chip select control pin #define TFT_DC 2 // Data Command control pin #define TFT_RST 4 // Reset pin (could connect to RST pin) #define An ILI9488 LCD controller driver for STM32 microcontrollers, using the HAL library. I would not recommend that, especially for a display with 480 x 320 pixels. The rest (HSPI controller) is hardwired inside ESP8266; WLCD_SPI_CLK_PREDIV and WLCD_SPI_CLK_CNTDIV determines the speed of HSPI clock - configure properly / test to match your LCD controller specification Aug 8, 2023 · I have no experience with your ILI9488 display and the corresponding library.
