Development Tools

To get started with the ST72F324BK2T3, you'll need a development board, a programming tool, and an integrated development environment (IDE) that supports the microcontroller. Fortunately, STMicroelectronics provides a range of tools and resources to make this process easy.

Here are some of the main tools you'll need:

ST72F324BK2T3 development board:There are several development boards available for the ST72F324BK2T3, including the ST72F324BJ6T6, which features the microcontroller, a USB connector, and a range of peripheral connectors.

ST-LINK/V2 programmer:The ST-LINK/V2 is a programming tool that allows you to program the microcontroller and debug your code using an IDE. It connects to your PC via USB and to the development board via SWD or JTAG.

IDE with SDCC compiler:STMicroelectronics provides a free and open source IDE called STVisual Develop (STVD) that supports the ST72F324BK2T3. However, it uses the SDCC compiler, which requires some additional setup. Alternatively, you can use other IDEs like Keil, IAR, or Eclipse with the appropriate plugin.

Once you have these tools set up, you can start writing and testing your code.

Programming the ST72F324BK2T3

Programming the ST72F324BK2T3 involves writing your code in C or assembly language, compiling it using a compiler like SDCC, and then programming the compiled code onto the microcontroller using the ST-LINK/V2 programmer.

Here are the basic steps:

1. Choose an IDE and set up your development environment.

2. Create a new project and configure the compiler options.

3. Write your code in C or assembly language.

4. Compile your code and check for errors and warnings.

5. Program the compiled code onto the microcontroller using the ST-LINK/V2 programmer.

Here's an example program that blinks an LED connected to pin PC0:

include define LED_PIN PC_ODR_ODR0void main(void){ unsigned int i; PC_DDR_DDR0 = 1; // configure PC0 as output PC_CR1_C10 = 1; // enable push-pull mode while (1) { LED_PIN = 1; // turn on LED for (i = 0; i < 50000; i++); // delay LED_PIN = 0; // turn off LED for (i = 0; i < 50000; i++); // delay }}

This example program illustrates some basic features of the ST72F324BK2T3, such as port configuration, control structures, and delays. You can modify this program to suit your own needs.
