How use to 0.96" 160x80 st7735s on NRF52840DK in SDK project nRF5_SDK_15.2.0_9412b96\examples\peripheral\gfx\pca10056\blank\ses

Hi,

 

Pin definitions in gfx project in sdk

#define ST7735_SCK_PIN 47

#define ST7735_MISO_PIN 46

#define ST7735_MOSI_PIN 45

#define ST7735_SS_PIN 44

#define ST7735_DC_PIN 42

#define ST7735_IRQ_PRIORITY 3

(SCL , SDA,RES,CS,BLK)The pins in the module are matched with which pins in the project.

Hi,

I see from your pin definitions that you are probably doing some SPI stuff, probably controlling a display (gfx reference and photo). There are also references to I2C signals. However, I did not see any problem description or question. Can you please elaborate?

[sema_tufan]

Yes, I'm working on screen control.
The pin names on the screen do not match the pin names in the gfx project. How to connect this screen to the NRF52840 dk board.

I see, that makes sense, as the GFX example use the ST7735 display driver. However, I do not understand the markings on your display module. Are you sure it has a ST7735? Wher did you get the display module? Is there any documentation for it with pin descriptions?

the product is sale in  this site

I see. The documentation for the pinout of the module is here (from the module datasheet):

Looking at the ST7735 datasheet, the pin names are a bit odd, but luckily someone has solved this before. Please try the mapping suggested in this post.

I've seen this post before. I made the connections in the photo.I've seen this post before and I've done the pin connection in this post, but the pin names in sdk_config.h are different. I've been trying to explain that since my first question.

I explained my question in the photo below.
