RM0013 LCD upside down

[TehSwedishChef]

I have just purchased the RM0013 and have installed a s Pi5 in it.

All works great except the LCD screen is upside down.

I have tried LCD rotate commands in the config.txt file however still no luck

NOTE - I have tried physically rotating the board however there is a hidden bezel that once installed puts a good portion of the screen behind the sled wall, so not happy with that option for the money paid

I have tried modifying the settings in the st7735.h file, specifically this section here

`
// mini 160x80 display (it's unlikely you want the default orientation)
/*
#define ST7735_IS_160X80 1
#define ST7735_XSTART 24
#define ST7735_YSTART 0
#define ST7735_WIDTH 80
#define ST7735_HEIGHT 160
//#define ST7735_ROTATION (ST7735_MADCTL_MX | ST7735_MADCTL_MY |ST7735_MADCTL_BGR)
#define ST7735_ROTATION (ST7735_MADCTL_BGR)
/
// mini 160x80, rotate left
/
#define ST7735_IS_160X80 1
#define ST7735_XSTART 0
#define ST7735_YSTART 24
#define ST7735_WIDTH 160
#define ST7735_HEIGHT 80
#define ST7735_ROTATION (ST7735_MADCTL_MX | ST7735_MADCTL_MV |ST7735_MADCTL_BGR)
*/

// mini 160x80, rotate right

#define ST7735_IS_160X80 1
#define ST7735_XSTART 0
#define ST7735_YSTART 24
#define ST7735_WIDTH 160
#define ST7735_HEIGHT 80
#define ST7735_ROTATION (ST7735_MADCTL_MY | ST7735_MADCTL_MV | ST7735_MADCTL_BGR)

/****************************/

After each time I have run the following commands

cd /home/*username*/SKU_RM0004 make clean make

And

./deployment_service.sh

Still no change

Hi!

I've found the solution to this problem. Go to the folder /SKU_RM004/hardware/st7735/ and open the file st7735.c. In this file, add a line between 194 and 195 and paste i2c_write_command(SCAN_DIRECTION_REG, 0x00, ST7735_ROTATION); into it.
Re-run the ./deployment_service.sh and you'll see that the screen will turn the right way.

I'll submit a PR to fix this problem.
