10W UV380/UV390 PLUS - WORK IN PROGRESS

[VK3KYY]

Hi !
I am attaching a screenshot from the TYT 390 Plus 10W radio station.
I have a 5W and 10W radio station available. The 10W version has a 50% lower backlight ( this is not a defect). I tried to put the front panel from 10W to the 5W version, and everything works correctly there. Including smooth brightness adjustment.

Did you try this version

downloads/MDUV380_DM1701/Firmware/88559 ... DUV380.zip

Yes. installed this version.

Sorry. Silly question. Of course you must have installed it.

Does FM still not work. ?

Make sure the screen is set to 100% brightness

PS for FM was the problem that the screen was not on , or did it completely not work ?

[R2ZFN]

Yes, it still doesn't work. Now I'm uploading videos to the exchanger.

OK. Thanks

Connect the USB cable to the radio

Open a terminal program to the COM port of the radio (I use Termite)

Send the letter D

Radio should respond with

Debug mode ON

If you don't get this response then check you are using the correct COM port number.
Disconnect and reconnect the terminal program

When you have successfully sent D and received "Debug mode ON"

Send this command

PD8 T

Response should be

PD8 T > Toggle pin D8 = Low

Send PD8 T

Response should be
PD8 T > Toggle pin D8 = High


This should be turning the LCB backlight on and off by directly controlling the GPIO pin on the CPU/MCU


Now try the radio in FM mode , when the screen goes off, and see if the screen comes back on again

PS.
The CPS functions do not work in Debug Mode
Rebooting will exit debug mode.

I checked - with the value - HIGH, the old version of the PCB is fine, but the new version of the PCB does not light up.

[VK3KYY]

I checked - when the value is - HIGH, it does not light up.

In DMR mode does toggling this pin turn the LCD backlight on / off ?


I should explain

The command is the GPIO pin name (PD8) and then the action of T for Toggle

It is also possible to send H and L to any output pin

e.g.

PD8 H

or

PD8 L

Also the command

PD8 O

sets the pin as Output, but it should already be set to Output

PD8 I

sets the pin to input, but this is not appropriate for this pin

PD8 ?

will read PD8

etc
etc

Guys

I will not be able to resolve the problem with the 10W radios myself, unless TYT decide to send me a 10W radio, which is unlikely as its almost impossible to get in touch with them.

I have now posted all the debugging tools and information that are necessary to understand the connection to the LCD backlight pin etc.

So I have to leave it to the owners of the radios which have the backlight problem, to attempt to probe this themselves, as described above

Because I don't have a UV380 Plus, and can't afford to buy yet another brand new radio to dissassemble and potentially damage, I'm not able to debug the problem some people are having with the backlight when the radio is set to FM


The exterimental version I posted a few days ago, has a serial terminal debugging function, which is accessed by sending the letter D to the radio
The radio should response with "Debug mode ON", if this does not happen, close and reopen the serial terminal connection and try again

Make sure the backlight brightness is set to 100%

Using the debug mode, you can read or write any of the pins listed above

Specifically if the radio is in FM mode and the backlight is not on, issue the command

PD8 H

This sill set the LCD backlight control signal to high and should turn on the backlight.

If this does not work, go into DMR mode, when in theory the backlight may be turned on, and try toggling the backlight On and off using

PD8 T

or
PD8 H
PD8 L

If this does not affect the backlight, then probably the backlight is no longer connected to pin PD8

In the list above there are a number of pins which are potentially unused, and these are described as TBD

To set a pin as output pin use

PxY O

e.g.

PC3 O

this should initially set PC3 to logic low

Now try

PC3 T

etc

If the pin does not seem to control the backlight, set it back to Input mode, otherwise you may damage the CPU chip

e.g.

PC3 I

Then try another TBD pin


If none of the TBD pins seem to control the backlight, then its hard to kow which other pin could have been repurposed if all other functionality in the radio is still working OK.

i.e It can't be using the SPI or I2C communication pins, or the PA control, or the Rx LNAs, etc otherwise the radio would not work correctly in DMR mode etc


PS.

When a pin is in Input mode you can use ? to read the value of that pin e.g.

PC3 ?
