HI,

First time posting here. so please go easy on me! :)

Been reading up on the forum and didnt find exactly what i was looking for.

Starting a project and was wondering about interfacing a Teensy 4.1 and a NHD-19232WG-BGGH-V#T display.
Ill have a lot of questions im sure, but the first one right now is, Are there any 'dont use those pins' when interfacing to the Teensy4.1? I've never used the teensy system yet. But we've been recommended the unit for our project.
The basic idea is that we need to have 3 rs422 ports for communication, we need to get a matrix of 5x6 keyboard keys for control and then we are also using the display NHD-19232WG-BGGH-V#T to show data etc.
So teensy was chosen for ease of use and having all we need already available.

For pinout from the display (which has 20 pins) we're a bit confused on whether we can just pin it on and assign the pins as needed or not?

Thank you for the help in advance!

This display has 16 pins, not 20. Interface has an 8 line data bus.Plus its 5V Not ideal, T4.x is 3.3V. Any existing libraries for the ST7920 will give you clues on how to connect.

Have you considered using a library like u8g2 or u8x8 and a different display supported by the library? spi or iic works great.
 
Heya! Thanks for the reply.
We’ve actually moved away from that display and decided to go with an oled that uses an spi interface.
Now gotta find a programmer or learn myself. Shouldn’t be terribly hard. Just gotta display some characters as they come in. :)
