Getting Started With STM32F103C8T6 Module with STM32CubeIDE

STM32F103C8T6 module is a 32-bit ARM Cortex-M3 CPU. I could operate up to 72MHz. Its Flash memory is 64kBytes, with its internal SRAM of 20kBytes. A popular chip in use is a 48-pin LQFP package. 

STM32F103C8T6 module

A typical module is made from the STM32F103C8T6 chip. It's a 44-pin chip.

A clone version of ST-LINK V2

This programmer is very simple, and easy to use with only four pins.

The STM32CubeIDE is an IDE from this device vendor. It's free to use. To get started with this IDE and the STM32F103C8T6 module. We will start a LED blinking program. Now I have downloaded and installed this program on my PC.

 After we build this project, we will need to upload its binary file to the module.

Wiring Diagram

I use ST-LINK software because I didn't update its firmware. If we its firmware update, we can use the ST-LINK V2 programmer in STM32CubeIDE.

Click on connect

Click on Open button to find bin file

Double click on bin file to open

Click on Program

Click on Start button

When programming finish

I test it on breadboard.

PIC18F4550 Programming Using MPLabX

PIC18F4550 is an enhanced Flash micro-controller with USB 2.0 feature. This device can operate up to 48MHz that yield the executing speed up to 12MIPS.

PIC18F4550 Family Data Summary

Program testing on target board

 There are some compilers available to program this device,

• MPLABX XC8
• MikroC Pro for PIC
• IAR for PIC18
• CCS PICC, and etc.

MPLABX XC8 is a free compiler from this device manufacturer. We can buy a paid version for a higher code generation quality.

In this example I use the MPLABX IDE to get start with this device programming. I use the latest version of MPLABX of 6.0, and the XC8 compiler of 2.40.

The program will chase the output LED(s) connect to PORTD.
