Hi everyone,
I have an upcoming project for my finals as electrical engineer and the project consists of a design of a touch screen interface for micro controller. As I am not that familiar programming I bought the STM discovery, extention and LCD boards in order to get more familiar with the programming. I am using IAR embedded software and downloaded the examples available on this forum. I started with an example that regards the LCD the project's name is LCD_35T. Currently I am struggling understanding a few things mainly the GPIO configuration. I have downloaded the manual of the STM board and read the sections of GPIO found under the stm32f4_discovery_lcd.c. However I cannot understand what each instruction is doing to each pin. Is there an explaination like a tutorial of this example?
Thank you in advance.
