How to use memory channel in uBITX with Nextion, TJC LCD

CEC Firmware supports a variety of LCD Types (The 16x02 LCD included with uBITX, 20x04 LCD, I2C type LCDS, and Nextion or TJC LCD)
The memory channel in uBITX started to be supported by CEC Firmware Version 1.0
The basic usage is the same in the latest version

Below is a way to use memory channels.

1.Memory Channel on Nextion LCD
CEC Firmware for Nextion LCD supports text mode. You can use all of the existing functions by using the text mode
Some of the functions have been made more convenient by using the touch function of the LCD.
This document describes how to use memory channels on the Nextion LCD a little more conveniently.

2.Storing Frequency

  1. Again Ian, great information. I had already figured much of this out just playing around with the display! Great work. Thanks for the editorial on how to use the memory functions. 73 Juddie WD8WV

  2. How to use paddle key in CEC 1.08 or upper version or in which version paddle key is available? de S21SM

      Of course you can use. You can use it exactly the way you used it in stock firmware.
      If you have used it in Stock firmware without any hardware modification, you can use it as it is. In addition, you can use uBITX Manager software (adjust adc range) to remove Paddle errortic.

Release CEC Firmware v1.200 for uBITX All version(include V2, V3, V4, V5)

Release CEC Firmware v1.200 for uBITX All Version (include v2, v3, v4, v5) I did the firmware work for v5 when uBITX V5 was released, but I release it now.
I received the feedback from a thankful beta tester and tested it myself by converting my uBITX v3 to v5 but I was not sure.

I ordered the uBITX V5 and delivered the correct uBITX V5, so I made a little more fine-tuning.
If you use V2, V3, V4, you do not need to update this firmware.
