Hi! I’m new to this… so hopefully I’ve put this post in the right place. I’m interested in connecting the [AST-CAN485 to a [1.3" Adafruit TFT LCD Display so I can show data read from an existing RS485 com bus. AST-CAN485 has the built in RS485 support and it also has an SPI that’s required by the TFT Display. The description of the AST-CAN485 says that its based on the Arduino Pro Mini , but it has an Atmel AT90CAN128 instead of the ATmega328. I’m a little confused about what that means exactly. Is it possible the use the AST AltSoftSerial library in coordination with the Ardunio SD library to write through the SPI to the microSD card that’s incorporated into the TFT Display breakout board? And what about using the Adafruit GFX library to draw text onto the TFT display? It’s kind of difficult to determine exactly what’s supported by the dev card. Maybe I’m not looking in the right place?](Adafruit 1.3 240x240 Wide Angle TFT LCD Display with MicroSD [ST7789] : ID 4313 : Adafruit Industries, Unique & fun DIY electronics and kits)](SparkFun AST-CAN485 Dev Board - DEV-14483 - SparkFun Electronics)
It mostly means that we tried keeping the pinout's and layout similar to the Pro Mini. However, there will be specific functions or other operations that will differ.The description of the AST-CAN485 says that its based on the Arduino Pro Mini , but it has an Atmel AT90CAN128 instead of the ATmega328.

As far as your desired application, we can not guarantee full compatibility, unfortunately.
