Image uploading and rendering with the use of my STM32 ST7735 library. Necessary steps for image preparing:
- creating the .png image
- converting it to RGB565 format
- saving pixels' values inside the array
- rendering stored data
All of this in detail - in my post. Example can be built with IAR Embedded Workbench (project files included) or can be used with any other IDE. The migrating process just includes copying .c and .h library files:
- st7735.c
- st7735.h
- st7735_image.c (for image data)
Project hardware and software set:
- STM32F103RE
- IAR Embedded Workbench
- STM32CubeMx
- HAL Driver
Physical connection:
- SPI1 for communication (only MOSI ans SCK needed - PB5 for MOSI signal, PB3 for SCK)
- PB7 (Reset)
- PC11 (CS)
- PB6 (DC)
