![]() (What I am really trying to learn is how to use an arduino nano to load photos from the SD card to the TFT screen. (Example nano's mosi pin pairs with LCD's miso pin? or nano's miso pin pairs with LCD's mosi pin? etc.)Īnd at last can I use the both the LCD and the SD card with just with one and only arduino nano? There are other boards like the Arduino Nano and the Arduino Mega, but UNO has been the go-to board for quick prototyping, Arduino Projects and DIY Projects. (Example mosi=pin? miso=pin? sclk=pin? ss=pin?)Īlso which pins to use of the SPI TFT LDC Module to pair it with nano? A complete guide on Arduino UNO Pinout, Board Layout, Technical Specifications, Important Features, Pin Description. For this i am using the pins as SO-> 50, SI-> 51, SCK-> 52 and CS-> 53 for the MCP2515 as only these are free after the Lcd shield is placed. Ideas? - Networking, Protocols, and Devices - Arduino Forum]Ĭould you tell me which pins to use in my nano for SPI communication(as a master)? I am trying to use the same code with Arduino Mega because i assumed MEGA has 2 SPI pins so I can power both MCP2515 and the Display at the same time. I dont know if there is a library for this. With a 2560, you can also use the USART as SPI, so you can have 2 SPI ports. ]]( After seeing all the post in arduino forum to find which pins to connect(miso,mosi,cslk,ss), I did not find anything but You would connect the two displays in parallel to MISO-MOSI-SCK and send data to one or the other using separate slave select for each one. ![]() Some devices have software SPI, but that doesnt mean you get to change Arduinos hardware SPI. ![]() Pin 10 is just a common and obvious choice. Each of the 54 digital pins on the Arduino 2560 Mega can be used as an input or output, using pinMode (), digitalWrite (), and digitalRead () functions. It is common to both Uno and Mega, while pins 11,13 are not SPI on Mega. I have an arduino nano V3 and trying to connect to an The ICSP cluster is simply an alternative set of the same pins.
