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 · 2024-11-23T02:01:26-0800

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

BGR / RGB

Is you screen still square?

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..
