uBITX with Nextion LCD (CEC Firmware) - Installation and Introduction

uBITX with Nextion LCD (CEC Firmware) - Installation and Introduction uBITX CEC Firmware supports various LCD since Version 1.08 (16x02 Parallel, 20x04 Parallel, 16x02  I2C, 20x04 I2C, 16x02 Dual LCD with I2C).
Supports Nextion LCD (Graphic LCD) from Version 1.09, Version 1.09x is primarily aimed at Nextion LCD support. Also 1.09x will continue to be Beta version. If you want a stable version, please use 1.08 or 1.1 version to be released in the future.

I do not know much about Nextion LCD. During the production of uBITX Firmware which is HF Transceiver, I was introduced by several OMs, The ultimate goal of this article is to create a GUI for the HF Transceiver.

uBITX CEC Version officially supports Nextion LCD from version 1.09.
I will support 2.4 "and 2.8" LCD by default. You do not need to understand everything below to connect uBITX Nextion LCD. Just use the Nextion Editor to load the firmware on the Nextion LCD. If you want to create your own GUI, please read these articles.

1.Nextion LCD?
 - It is a TFT LCD with built-in Font, Control etc. required for GUI
  This is why you can use the graphical GUI on small size MCUs like Arduino.

Old Photo#2 - Cortex M0 - Hand Packaging

Old Photo#2 - Cortex M0 Hand Packaging

I found a old photo on Google Photos.

The designed Cortex M0 was delivered to the factory, One of the master students commuted to the factory and finished all the debugging and waited until it was produced.
The Master had planned to complete the paper by measuring the performance in the produced Cortex M0.

At the time when the submission date was short, I was informed that the Cortex M0 was made.
To use the factory-produced Cortex M0, need to package it.  However, according to the schedule delivered by the packaging vendor, the packaging of the Cortex M0 can not be completed within the submission period.

There was a problem.

We had to find another way.
Let's try soldering by hand!
We had to venture.

We've practiced to see if this is possible.


We practiced once and we realized the importance of double-sided tape.


I can not find what was in the picture right now.

The student who wrote using this mcu now graduates and works at a semiconducto…
