STM32F429 inside CooCox CoIDE

Because STM32F429 is not supported by Coocox CoIDE with all of its features, I downloaded CMSIS files for STM32F429 from ST’s web site, version 1.3.0. I created a new project for STM32F407 and replaced files with downloaded for STM32F429. Now you can work with both discovery boards in Coocox, but I prefer working with Keil uVision (step-by-step tutorial for Keil uVision). Also, Coocox does not support 2MB flash yet, only for 1MB, what is fixed in Keil. All CMSIS files...

Library 05- SPI for STM32F4

Let’s say something about SPI. SPI (or Serial Peripheral Interface) is a protocol named by Motorola. With him you can control sensors, SD card and much more. SPI protocol works in a ways where there is one master and multiple slaves, In other words, master is our STM32F429 Discovery board and let’s say, SD card is slave.

Library 03- STM32F4 system clock and delay functions

In first tutorial about discovery board we were blinking led. But I said nothing about system clock speed. In while loop we just use

for some delay, to actually see how led was blinking. We didn’t know at which clock speed our processors work and for first time, I think you didn’t even ask yourself.

Library 02- STM32F429 Discovery GPIO tutorial with onboard leds and button

Your first blinky project works, but you don’t know how? I will explain GPIO (General Purpose Input/Output) CMSIS Library. This library is used to work with physical pins on microcontroller. You can set pins to input or output, put them low (0 volts) or HIGH (3,3 volts), select pull resistors, choose output type and select clock speed.

01- First time with STM32F429 Discovery

Ok, you got your STM32F429 DIscovery board and you don’t know how to use it. In this tutorial I will explain how to use this board with CooCox IDE. I prefer install from their CoCenter. You will need to download ARM GCC from here. There is also youtube tutorial, make sure you did all correct.
