uBITX v5 with 20x4 screen(s) #ubitx-help #firmware

I have built and tested my v5, tuned in WWV and it was spot on..  next on the list is to test TX..  need to get the antenna to a happy SWR

I was given 2 20x4 blue screens, it comes up fine with 2 lines by about 16 wide.  Is there a setting in factory firmware for the 4 line screen? CEC v1.121 still have settings for it?  Did I see a reference to using a second screen?  Trying to do what I can with what I have even though the nextion screen looks so cool..

You have to do some alterations in the firmware sketch yourself. Line 1 is indicated as 0. Line 2 as 1. Line 3 and 4 will then be 2 and 3. Line 3 and 4 you have to add. And what data you want there. There is no setting that will do it for you as far as I know.

CEC firmware has support for 20x4.  I am building a 20x4 myself.

you need to load the appropriate hex file  from the repository - there is a specific set for 20x4 - either parallel or I2C

Thank you all..  

Looks like I need to compile/download CEC v1.20 .. does it default to 20x4 screen as in v1.072?
I have not found a manual after v1.072

Is I2C a different screen or different way to talk to the same screen?

What a fun new adventure..

Download the v1.2 binaries and read the document on file naming conventions to find the 20x4 file you need to flash.

Bill, I've finally had a chance to get on my laptop. For the 20x4
display, these are the relevant files from the CEC v1.2 binaries.

UBITXV5_CEC_Vxxxxx_20P.hex : 20x04 Parallel LCD
UBITXV5_CEC_Vxxxxx_20P_S.hex : _20P with I2C Meter

UBITXV5_CEC_Vxxxxx_20I.hex : 20x04 I2C LCD
UBITXV5_CEC_Vxxxxx_20I_S.hex : _20I with I2C Meter

I2C is a two-wire serial bus some people switch to in order to free
some Arduino pins. It sounds like you dont have an I2C panel so you
would want the first firmware on the above list. "I2C Meter" is used
by the CEC S-Meter circuit discussed on the CEC website.

The v1,2 binaries are here:
https://github.com/phdlee/ubitx/releases/download/v1.20/uBITX_CEC_V1.200.zip

Enjoy!
