This is the first of two chapters in which we are going to start investigating the SPI data bus, and how we can control devices using it with our Arduino systems. com. e Pixel resolution: 240 x 320). we can recognise your display. Toggle Nav. The encoder pulses are going to an LS7366 counter via SPI. is These displays use 4-wire SPI to communicate and have their own pixel-addressable frame buffer, and can be used with every kind of microcontroller. You have paired a relatively high-resolution, colour LCD with a small, slow, limited memory Arduino. I've downloaded the Arduino GFX 1. I think what may NOT be clear to YOU is that the function of a backpack is to provide a plug & play adaptor into which you can plug a regular 16 pin 1602 parallel lcd (that has a male to male header attached) into and use as either an I2C OR SPI, depending on the particular adaptor. 5KHz. You can use the same 14x1 header for all these displays. I wonder if somebody help me to connect the lcd to the arduino, this are the pins from my LCD: Pin Name 1 SCL 2 SDA 3 A0 4 RSTB 5 CSB 6 VDD 7 VSS 8 V0 9 XV0 10 VG 11 A 12 K I tried to use the ug8lib but I think There is not much point in wasting time over ESP8266 I2C if VR1 does not achieve visible contrast with VCC=3. DC PIN - PIN 10 RST PIN - PIN 11 I have an "az-atmega328-board" and a "2,8 Zoll LCD TFT Touch Display - Kompatibel mit Arduino und Raspberry Pi - 320x240px Auflösung, ILI9341 Treiber, SPI Schnitts".
