The NH4 is essentially the same as our Samsung 4.3" touchscreen
adapters, just modified and fine tuned for the Newhaven 4.3"
touchscreens that are available from Digikey and Mouser.
|
All code for the Samsung (PSB) displays is easily modified to
run on NH4, such as the Paint program: |
|
|
|
|
The NH4 is designed to plug directly into the upper row of pins on a
Propeller Platform compatible board, but it can easily be used on a
breadboard or other Propeller proto setup also. |
|
Here's a photo of the NH4 connected to a Propeller Platform and a
Newhaven 4.3" LCD:

|
|
Note that this is a "bottom contacts" only connector, so it
won't work if plugged in upside down. |

|
|
Update: Newhaven displays now with better polarizer
|
New compatible part numbers are:

Capacitive Touch
|
You can now use Newhaven's capacitive touch 4.3" screens with the
NH4 by adding a small breakout to the setup and running 4 jumper wires
as shown here:
|
Breakout boards are only $3 with free USPS shipping. |
|
|
|
|
|
Example Code
|
Note: If not using the upper row of pins on a Propeller
Platform board, you will probably need to adjust the pin settings in
these files. |
|
|
Lets you draw in the screen with stylus or fingertip as shown in
a picture above. |
|
This is a quick adaptation of PSB Paint as NH4 is very similar
to the Samsung 4.3" breakouts and boards. |

|
This is an adaptation of the Propeller Graphics Demo for TV.
