It comes with more memory space and I/O pins as compared to other boards available in the market. SPI is somewhat similar but you need a hardware CS for each device. Arduino Mega 2560 is a Microcontroller board based on Atmega2560. Lcd.print('Hello Gil!') // Print a message to the LCD. Lcd.setCursor(0,0) // Point cursor to row 0 column 0 This actually would allow up to 8 displays. Each display on the I2C buss needs initializing but no additional pins required. the third parameter is how many lines are on your screen the second parameter is how characters per row are on your screen the first parameter is the I2C address (0x27) LiquidCrystal_I2C lcd(0x26,16,2) // set the LCD address to 0x26 for a 16 chars a line and 2 line display LiquidCrystal_I2C lcd(0x27,20,4) // set the LCD address to 0x27 for a 20 chars a line and 4 line display Defining pin numbers is dependent on the library you are using. Same for the SPI except the select (CS) pins. Just a hint, all the I2C devices connect on the same two pins. Right now I'm just trying to see if this idea will even work. I thought I would review the examples for the touch screen and go from there.

NOTE: I haven't figured out the code part yet, which is why I haven't included it. If you want to know what pin the on-board LED is connected to on your Arduino. the correct LED pin independent of which board is used. it is attached to digital pin 13, on MKR1000 on pin 6. (I saw on previous forums that there is a way to connect the two have the Uno as the master and the mega as the slave) Most Arduinos have an on-board LED you can control.

Should I use the Uno for the Touch screen shield, and the mega for the LED panel? La carte Mega est donc plus puissante, permet une marge de manuvre beaucoup plus importante et des montages plus poussés qu’avec d’autres cartes Arduino. (So that I can fit the touch screen shield onto the mega and still have enough pins for the LED panel)ĭo I have to change the pins in the libraries or can that be done in the sketch/program code? Is it possible to change the pins that the LED panel requires?

The shield covers digital pins 9-11, and analog pins A0-A3 - which the LED panel needs. If I put the Touch screen shield onto the Mega, I need to change some of the pins for the LED panel. If I put the Touch screen shield onto the UNO, there are no pins left for the LED panel. I have tested each device and they all work normally. I have downloaded the correct libraries for each device. My project is this: I want to click on a button on a touch screen, and have a pattern run on a LED panel.ġx Adafruit 2.8' TFT Touch Shield for Arduino with Resistive Touch Screen ( Overview | Adafruit 2.8' TFT Touch Shield v2 - Capacitive or Resistive | Adafruit Learning System)ġx Adafruit 32x32 RGB LED matrix panel ( Overview | 32x16 and 32x32 RGB LED Matrix | Adafruit Learning System)ġ large solder-less breadboard, 1 small solder-less breadboard, jumper wires, OM meter and other assorted electronic paraphernalia.

Hi, I'm hoping I posted this in the right place.
