Nextion, TJC, Character LCD current consumption

Nextion, TJC, Character LCD current consumption
When using Nextion LCD, the first question I get is 'What is the current consumption?' I do not know. I did not even know the name of Nextion LCD until recently.
CEC Firmware Users continued to talk about Nextion LCD, so I got to know Nextion LCD. I even confused TJC LCD and Nextion LCD.

Creating a simple S-Meter Sensor for uBITX (LM358 Version)

Creating a simple S-Meter Sensor for uBITX (LM358 Version)
If you are already using S-Meter, you do not need to view this document. This document is for those who do not have an S-Meter Sensor or want to use some of the features using S-Meter on the Nextion LCD. There are various ways to attach S.Meter to uBITX. You can find things on the Internet that are far superior to what I have created.

uBITX Firmware CEC version is based on unmodified uBITX. However, to see the strength of the received signal, you have to attach the sensor. Of course, there is no problem in using CEC firmware without a signal meter sensor. Most people I know have not installed an S-meter yet.

uBITX Firmware CEC Version 1.094Beta Release(Include Nextion, TJC GUI Firmware)

uBITX Firmware CEC Version 1.094Beta  Release (Include  Nextion LCD and TJC LCD GUI Firmware)
uBITX firmware CEC Version is based on uBITX which has not modified anything. Prior to deployment, the 16x02 LCD with built-in is tested first. Nextion LCD, TJC LCD, 20x04 LCD and I2C LCD are not essential for using uBITX Firmware CEC version.
This version is not significantly different from version 1.08. Nextion LCD and TJC LCD is added to 1.09x version

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.

How to use Nextion LCD #3 - Practice for use with a transceiver

How to use Nextion LCD #3 - Practice for use with a transceiver
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.
