Make 1.8 SPI TFT 128x160 works as Arduino project display

Almost a week I tried to make this display worked. I tried few pinouts combination and few library and still it won't work. Finally I managed to get this display working with Ucglib library and help from internet and doing trial and error.

There are several type of this display on the internet. You can search this kind of display and it's variation. But the one I have sadly has common problem. Here is mine.

And here is in the back of the lcd.

Wiring

The pinouts could be different on other type. But here are the pinouts that working for me. Note that first pin is GND. All pin used are digital pins.

GND <-----> GND
VCC <-----> 5v
RESET (RST) <-----> PIN 8 (in series with 1K resistor)
AO (DC) <------> PIN 9 (in series with 1K resistor)
SDA <-----> PIN 11 (in series with 1K resistor)
SCL <------> PIN 13 (in series with 1K resistor)
CS <-----> PIN 10 (in series with 1K resistor)
LED+ <-----> 3.3v
LED- <-----> GND

I need to add resistor in series with all used pins. I found this resistors make better color contrast. Maybe the lcd pinouts was intended to work on 3.3v.

Libraries

Install Ucglib library from Arduino Libraries or you can download it from link on the top.

Testing

Download my test sketch on: https://github.com/satujamsaja/Arduino/tree/master/spitft1.8 it should show like below. My other sketch will display sensors results. You can download it on this link https://github.com/satujamsaja/Arduino/tree/master/spitftdht22bmp280 and also check the sensors wiring on my previous posts.

Good Luck.

Using LCD 2004a I2C on project with Arduino

On previous post measurement sensor results displayed on serial monitor. This is good when we are on development stage. When we want something more independent we need external display. I have purchased a few type of display. For now we will use LCD 2004 for external display.

Arduino : Controlling PL9823-F8 RGB LED

I have great passion about electronics since I was in middle school then high school. With some of my school friend that has same passion in electronics, we built radio transmitter so we can communicate each other at anytime. It was so cool back then. Thats why I took study on electrical Engineering. Instead of working on Electrical engineering field, I end up become web programmer. Something I found interesting when i was in college. That's old story. But lately I get bored and try to get another hobby. I have many hobbies and creating electronics stuff is one of it. So I bought my self Arduino Uno and few electronic components to get started learning Arduino programming. So my first project is controlling RGB Led. Here what you need: Arduino Uno with usb data cable and Arduino IDE Install Adafruit Neopixel library 3 PL9823 RGB led Breadboard Jumper cables (mostly male to male) First you need to install Arduino IDE. You can download it here . That would d...

Read temperature and barometric pressure from GY BMP 280 using Arduino

This sensor based on BMP 280 digital pressure sensor made by Bosch. You can find the complete datasheet here . This small sensor is quite impressive with it's accuracy. It claimed to be ±1 hPa in measuring barometric pressure, ±1.0°C in temperature measurement and ±1 meter in altitude accuracy. Pretty impressive right ?
