Display TFT ST7789 (OshonSoft Basic).

DogFlu66 · Jun 7, 2024

I leave the library to use ST7789 TFT display, I have translated one that is in C language. But unfortunately I have not been able to get it to work yet. I leave the files in case someone with more experience with these displays can review it.

Its in the INIT routine just above the INVON call..

Hi I,
I posted earlier that I had changed INVON to INVOFF to get the correct colours

Just above INVON is:
Call LCD_WRITE_COM(ILI9341_MADCTL)
Call LCD_WRITE_DATA(0x8)
Call LCD_WRITE_COM(ILI9341_INVOFF)'(ILI9341_INVON)

But I don't see any of the ILI9341_MADCTL_?? section used within the program itself, but there is ILI9341_MADCTL used within the program.

Also in #164 there is no ILI9341_MADCTL_MH.

Could you post your latset working program please.

P.S, An alarm has just gone off in the house, and I can smell electrical smoke. It maybe the central heating pump

Sorry Cam.. write are command.. then data so ..
Call LCD_WRITE_COM(ILI9341_MADCTL)
Call LCD_WRITE_DATA(0x8)

Change the second line to 0x3C tell me what happens..

Hi,
Re P.S on #202

I found the problem, it was the starting cap of the central heating pump. Luckily I had a spare, changed it and the heating is back on

Now where was I.

Hi I,
No change

Hi,
Some of the colours were wrong so this is correct for my screen:
C

Code:

Const LCD_BLACK = 0x0000
Const LCD_RED = 0xf800 '0x001f
Const LCD_BLUE =  0x001f' 0xf800
Const LCD_GREEN = 0x07E0
Const LCD_YELLOW = 0xffe0'0x07ff
Const LCD_MAGENTA = 0xf81f
Const LCD_CYAN = 0x07ff '0xffe0
Const LCD_WHITE = 0xffff

Ian Rogers · Nov 23, 2024

LOL.. Now you know about MADCTRL! Bit 4 changes this for you RedGreenBlue or BlueGreenRed

BGR / RGB

Hi I,
My screen is 240X320

Your CODE jams at: Call LCD_WRITE_COM(ILI9341_SWRESET)
Can you post your DIMS also please?

TFT GMT020-02 (ST7789):

To operate the SPI at 16 MHz SCL, I need to set it to Mode 2.
_SPI1_Init(_SPI_MODE2, _SPI_MASTER_SPEED0 | _SPI_ENABLE) 'SCL 16Mhz (64Mhz).

On my LCD, I must keep the command LCD_WRITE_COM(ST7789_INVON) active to ensure the colors display correctly.

However on the GMT320 (ST7789) it has to be: LCD_WRITE_COM(ST7789_INVOFF).

Everything seems to work fine in full screen.

The MADCTRL is only different on the ILI9341 The rotaion is not right out of the box..

I have set the rotation using the MV only ( horiz / vert ) swap and it works as expected.

This is bit 6.. However! I have to set the RGB as I couldn't be bothered working out the colours..

RRRR|RGGG|GGGB|BBBB is 565 format BBBB|BGGG|GGGR|RRRR is how I have it..

Hi I and D,
How are you actually changing these settings?
Can you give me an example of before and after? please?
I keep changing settings and nothing is happening, apart from
[ Call LCD_WRITE_COM(ILI9341_INVOFF)'(ILI9341_INVON) ]
which did reverse the colours.

Code:

    //WaitMs 1
    Call LCD_WRITE_COM(ST7789_MADCTL)
    Call LCD_WRITE_DATA(0x8)

    Call LCD_WRITE_COM(ST7789_INVOFF)

Look at the code above.. It only need doing once ( Until I do a complete rotation)

The way the system works is:- You issue the command write to the MADCTRL then the LCD waits for the data.. The second write is data. the third write is the command to swap inversion.

The LCD_WRITE_DATA above is the data for that command.
____________________________________________
| MY | MX | MV | ML | BGR | MH | XX | XX | << 1 byte DATA for MADCTRL

You see above that I have bit 4 switched on which swaps RGB to BGR

If you set bit 6 MV it swaps from Horizontal to vertical and back..

My ST7789V is working fine with the code I sent in #208

Hi I,
Thanks.
If I change Call LCD_WRITE_COM(ST7789_INVOFF) to ON, it changes, but if I change Call LCD_WRITE_DATA(0x8) to a varety of settings, nothing changes?

Hi I,
I've just noticed, that this is for ST7789, no wonder I can't get it to work

Can you post our ILI9341 CODE once you have it working ok, please?

TFT GMT020-02 (ST7789):

To operate the SPI at 16 MHz SCL, I need to set it to Mode 2.
_SPI1_Init(_SPI_MODE2, _SPI_MASTER_SPEED0 | _SPI_ENABLE) 'SCL 16Mhz (64Mhz).

On my LCD, I must keep the command LCD_WRITE_COM(ST7789_INVON) active to ensure the colors display correctly.

However on the GMT320 (ST7789) it has to be: LCD_WRITE_COM(ST7789_INVOFF).

Everything seems to work fine in full screen.

For the current color table the configuration is as follows:

TFT GMT020-02 (ST7789):
Call LCD_WRITE_COM(ST7789_MADCTL)
Call LCD_WRITE_DATA(0x08)
Call LCD_WRITE_COM(ST7789_INVON)
TFT GMT320 (ST7789):
Call LCD_WRITE_COM(ST7789_MADCTL)
Call LCD_WRITE_DATA(0x08)
Call LCD_WRITE_COM(ST7789_INVOFF)

Hi C... The only difference between the two IS the MADCTRL..

The code I have pasteted before was for the ILI9341.

MADCTRL is 0x28.. Bit 6 MV swaps horiz / vertical BUT.. If your screen is partial we need to look at the direction as well.

On line I found code from RinkyDink and his MADCTRL is 0x48 and rotated 180, was 0x88

Remember! you changed the colour to suit

Ian Rogers · Nov 24, 2024

Here is my current code.

I have changed the font to a larger one but it is only size one.

BE CAREFUL.. The font data is on two lines so it needs to be one in the IDE, but Vlad uses a separator
You'll see...

All ok.

TFT 3.2V MSP3218 (ILI9341):
Call LCD_WRITE_COM(ILI9341_MADCTL)
Call LCD_WRITE_DATA(0x20)
Llamar a LCD_WRITE_COM(ILI9341_INVOFF)

This TFT is more affected by parasitic capacitances and I cannot get it to work at 16Mhz.
