![]() ![]() It did display text and drawings, but there was a lot of noise in the image and the images were streaky down the screen. However, when I hooked up my board following the Adafruit guide, my display sort of worked. After I received the screen and realized I didn't know how to hook it up I turned to the Adafruit guide for their product.Īt first, it looked like the pin lay out was different but otherwise the two displays were interchangeable and able to run the Adafruit Graphics library (more on the code in the next step). This is the step that I wish I had been able to find more easily when I started with this board. Now that we know what we're dealing with it's time to start wiring! GND - this is the power and signal ground pin Connect to 5VDC to turn on the backlight. ![]() Vcc - this is the power pin, connect to 5VDC - it has reverse polarity protection but try to wire it right!īL - this is the input for the backlight control. Connect to ground to reset the TFT! Its best to have this pin controlled by the library so the display is reset cleanly, but you can also connect it to the Arduino Reset pin, which works for most cases.ĭ/C - this is the TFT SPI data or command selector pinĭIN - this is the SPI Master Out Slave In pin (MOSI), it is used to send data from the microcontroller to the SD card and/or TFT The opposite side with 16 pins is for using the SD card, which will be addressed in a later Instructable.Ī brief summary of the pins (adapted from Adafruits thorough summary): It has 8 pins and you can see what each pin corresponds to in the second photo. There are two sides of pins - the side circled in red is the side we will be working with. The first photo here shows the back of the display board. ![]()
