Default [M0NWK] OLED Display for Minitiouner V2


OLED Display for Minitiouner V2

Posted: 14 Mar 2019 07:43 AM PDT

Its 11th March 2019 and Ive just added an OLED display to my MiniTiouner. A
simple, low cost, low effort addition to an already brilliant piece of kit.

This blog post shows how I did it.

Click the continue button to see more.

For this project I am using MiniTiouner V2 and MiniTioune v0.8 software.

Below is a list of parts I used in this project:

1.3 12864 IIC I2C SPI OLED display module
1 x 5 (or 3) pin HARWIN female connector
1 x 4 pin HARWIN female connector
8 x crimp connectors for HARWIN female connectors
4 x wires each of a different colour (I use alarm wire)


Im not going to go into how I2C works. If you want to learn more about I2C
see linkĀ*here for a good explanation.

The I2C OLED has four pins; VCC, GND, SCL and SDA.


Looking at the MiniTiouner PCB you can see J7 (highlighted red) has GND,
SCL and SDA pins but no +VCC.

I will be connecting the OLED +VCC to jumper J2 (highlighted yellow). I set
the DC-DC regulator to 3.75V when I initially built the MiniTiouner.


I made a small wiring loom. The 4 pin female connector is to be connected
to the OLED. The 5 pin female connector is for connecting to the J7 on the
MiniTiouner PCB. You could use a 3 pin connector as there are only 3 wires
but I think it looks more professional using 5.

I soldered the +VCC wire to the jumper for J2, which I made for the initial

The photo below shows the connections from OLED to J2 and J7 on the
MiniTiouner PCB.


In the MiniTioune v0.8 directory is a file called minitioune.ini.

I opened the file and located the Display section. I changed value OLED=no
to OLED=yes.

I saved and closed the file.

I connected an antenna and power to the MiniTiouner then connected the
MiniTiouner to my PC using USB cable.

Power to the MiniTiouner was turned on and I opened the MiniTioune software
on the computer.

As soon as the software opened information was displayed on the OLED.

I checked the OLED was displaying the same information as displayed in the
software and it was.


In the near future I will cut a window for the OLED in the front panel
using my milling machine.
