@retroprogrammer i see in your fbtft.config file you have bgr=1, can you remove it and let me know if that works?

That should resolve your colour problem

[retroprogrammer]

@Hex No still same problem

[retroprogrammer]

@Hex Is their a way of making the screen a bit bigger?

[Hex]

how about bgr=0

The problem is that your blue and red channels are switched and this is the only way to resolve this. If this doesnt work then you will have to try different device names as some device_names dont support the BGR parameter (let me know if you need those).

From the author of fbtft:

bgr :
Set BGR bit (supported by some drivers). Use if Red and Blue is swapped. Default is don't touch.

The best way is to buy a new screen that is bigger. Else you could try my Viper frontend, which is in works currently. Even i was unhappy with the performance of ES on smaller screens. Here are some of the photos of my frontend. The screen is 320x240 @ 2.2inch.

@Hex bgr=0 doesn't work either, I think the red and blue are swapped around or something, I need to know the device_ names please.

Take a look at this thread. the author also had the same problem and was able to get it resolved https://github.com/notro/fbtft/issues/156

I use 1.8TFT that similar the red board one but it use st7735S. I config following the tutorial but no luck the screen keep white. what should I do ; w;

[juj]

I recently added support for 160x128 ST7735R display to my https://github.com/juj/fbcp-ili9341 display driver. Perhaps it is close enough to ST7735S that it might work there as well by reusing ST7735R options, if you're interested to hack on it a little.

@juj I try this command:
git clone https://github.com/juj/fbcp-ili9341.git
cd fbcp-ili9341
mkdir build
cd build
cmake -DST7735R=ON -DPI_ZERO=ON -DGPIO_TFT_DATA_CONTROL=24 -DGPIO_TFT_RESET_PIN=25 -DSPI_BUS_CLOCK_DIVISOR=6 ..
make -j
sudo ./fbcp-ili9341
(I use pi zero not zero w)

I use https://www.aliexpress.com/item/1-8-inch-TFT-LCD-Display-module-ST7735S-128x160-51-AVR-STM32-ARM-8-16-bit/2055099048.html?spm=2114.search0204.3.30.14dd7e5bb5f8hn&ws_ab_test=searchweb0_0,searchweb201602_1_10152_10151_10065_10344_10068_10342_10343_5722611_10340_10341_10696_5722911_5722811_5722711_10084_10083_10618_10307_10059_100031_10103_10624_10623_10622_10621_10620_5722511-10620normal#cfs,searchweb201603_11,ppcSwitch_2_ppcChannel&algo_expid=320e54af-4cc8-48be-be2c-2dc33de19d12-4&algo_pvid=320e54af-4cc8-48be-be2c-2dc33de19d12&priceBeautifyAB=0
and connect with

but it does not work what I do wrong? (I quite new to Raspberry Pi)

[juj]

Not exactly sure, the initialization does look good. Try checking through the FAQ and Troubleshooting list if anything in there particular might be relevant: https://github.com/juj/fbcp-ili9341#faq-and-troubleshooting . If not, it might be that there's something essentially different between ST7735R and ST7735S that will need to be taken into account. If you find the spec sheets for both, perhaps you'll be able to spot a crucial difference?

@juj Thank you, I think I should try change the GPIO pin if any progress I will report again :)
