i understand the different char set...
what i mean is that the Trim-Curser behaves different in the one and the other direction.
i have to click 20 times to go the cursor 1 position left.
i have to click1 time to go the cursor 1 position right
(tested with F7 and also F7 simulator)
F12 simulator left and right trim is the same

Yes, I see. Trim value changes correctly but cursor position changes incorrectly. I will look into it.

I think there is a coarse and a fine adjustment. If you do single click it takes about 20 clicks between the markers but if you hold the trim button it rapidly goes from mark to mark. It was intended that way, as I assume. If it gives sufficient feedback for some that depends. I prefer to do sub-trim for my helis, but for wings it might be different, I don't know since I don't have any

Cheers

With trim cursor it's the problem of integer division rounding. It can't be fixed ideally, but now it will looks more naturally. (x / y) changed to (x + y / 2) / y.

i would prefer, if the cursor moves at the first click...otherwise it would be hard to know in which direction the trimming is for the vertical trims (ele,thr)

About Cursor in the menue:
Ive looked into the most menue points.
There should be enouph space to have it this way

 menu1
>menu2
 menu3

instead of

menu1
>menu2
menu3

This would be much better for readability
What do you think?
Is this hard to implement?

I think it would be also a good idea to center the menu headlines for better readability

Sorry for my bad english

Hello vlad_vy

I hope this question is not clarified else ..

My question is: is there anywhere a sheet with video channel belongs to which frequency ?

In the moment i have some trouble with a MATEK VTX and the HGLRC F4 V5Pro (onboard VTX). I have found this

www.aziermann.de/Tank/FPV%20Frequenz%20%C3%9Cbersicht.xlsx

According to this sheet - i swichted the my VTX to 5765Mhz (description) - but at channel 19 on my F12E - nothing - i have an acceptable picture on channel 6.

Thanks for your help

Thank you a lot for your fast information.

The reason why i ask - my Matek VTX makes a terrible picture on my both F12E with a PAL-Cam (i have tested several cams) - independent of firmware (Deviation - or Walkera). I have no problem with another monitor (i have a 7 Zoll with diversitiy also - picture is ok) - and i have no problem with another VTX and F12E. For example the HGLRC F4 V5Pro Board is sending a fine picture to the F12E.

On Fatshark cam - i can switch to NTSC - and then the picture is ok. Is the reciever of the F12E so "poor" ?

void LCD_PrintCharXY(unsigned int x, unsigned int y, u32 c)
{
    c = TW8816_map_char(c);
    if (x >= LCD_WIDTH)
        x = LCD_WIDTH-1;
    u32 pos = ((y >> 1)*(LCD_WIDTH>>1)) + (x>>1);
    //printf("%02x(%c): %d, %d, %d\n", c, c, x, y, pos);
    TW8816_DisplayCharacter(pos, c, 7);
}

TW8816_DisplayCharacter(pos, c, 7);

I think '7' is the white color, 0111 -> FFh (111,111,11), page 17 of TW8816 datasheet.

Hi vlad_vy,

I got a used F7 last week and would like to mod. it to XMS version. 2 stupid questions.

1, If I want to back to Walkera FW , is it just change SPI flash to original UPCT25VF512A?
2, What's correctly step ? change SPI flash memory then upgrade Deviation XMS FW or I should upgrade Deviation XMS FW first?

Thank you very much.

edit:
Is there any difference between SST25VF032B-50-4C-S2AF and SST25VF032B-80-4I-S2AF?

1. To return back to Walkera FW you need return back original flash memory chip.
2. Change flash memory chip then upgrade to Deviation XMS. You can do it by any way, XMS support flash memory auto detection, but other way has not sense, you can't write filesystem to small memory chip.
3. They differ by operating frequency 50MHz and 80MHz. I think you can use any of them, but with my case it was 80MHz chip.

Hi vlad_vy,

I destroyed a solder pad of my flash memory as attached picture , is it possible to connect that pin to other solder point? or I have destroyed the TX?
Thank you very much!

With Devo F4 it can be (pin connections from SST25VF032B to STM32F103RBT6):
1. CE = SPI1_CE (PB2, pin 28)
2. SO = SPI1_MISO (PA6, pin 22)
3. WP = 3.3V (VDD_4, pin 19)
4. VSS = GND (VSS_4, pin 18)
5. SI = SPI1_MOSI (PA7, pin 23)
6. SCK = SPI1_SCK (PA5, pin 21)
7. HOLD = 3.3V (VDD_4, pin 19)
8. VDD = 3.3V (VDD_4, pin 19)

If Devo F7 connections are similar to Devo F4.

2. SO = SPI1_MISO (PA6, pin 22)

Why not to use via near destroyed a solder pad (IC4 pin 2), or connect pin 2 to via near IC4 pin 5.

That happened to me. You can use the other end of the lead. That's what I did and my F12E is working with no issues. Just watch your soldier iron to avoid damaging the other components.
