Solo Project: STM32-based Piano Instrument

Piano is a melodic musical instrument that can produce tones when pressed. This musical instrument is in demand by many people because of its beautiful sound harmonization. However, its expensive price in the market makes some people unable to afford it. Therefore, this project was created with the aim of letting the general public know that pianos can actually be assembled by themselves, so price will no longer be a barrier. This will certainly be very beneficial for the wider community, because in addition to cutting costs, you can also customize it. This project has been done and took approximately 4 days. The results of this study show that the system can function properly.

Wiring

Basic Knowledge

Basically, a device can be communicated with other devices either wirelessly or by cable. Communication between commonly used hardware is Serial Communication. It can be known that there are three types of Serial Communication, which include: UART (Universal Asynchronous Receiver-Transmitter), SPI (Serial Peripheral Interface), and I2C (Inter Integrated Circuit). There are two kinds of UART Serial Communication, namely Hardware Serial and Software Serial. Hardware serial communication can be done by connecting the TX and RX pins crosswise on each development board, for example: RX-TX, then TX-RX. The TX pin is for sending data, while the RX pin is for receiving data. Serial Software Communication is more or less the same as Serial Hardware Communication in terms of cabling, but there are differences in terms of coding. By using this Serial Software you can overcome the constraints of the limitations of RX and TX pins on the development board. To communicate with this Serial Software is quite easy, namely by using certain Digital Pins as a substitute for TX pins and RX pins.

Arduino IDE Setup

1. Open the Arduino IDE first, then open this project by clicking File -> Open :

   pianomini_stm32.ino

   
   

2. Fill in the Additional Board Manager URLs in Arduino IDE

   Click File -> Preferences -> enter the Boards Manager Url by copying the following link : https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmicroelectronics_index.json

   
   

3. Board Setup in Arduino IDE

   How to setup the STM32F103C8T6 board
   • Click Tools -> Board -> Boards Manager -> Install STM32 MCU based boards. • Then click Tools -> Board -> STM32 boards groups -> Generic STM32F1 series.

   
   

4. Change Board Part Number in Arduino IDE

   Click Tools -> Board part number -> BluePill F103C8

   
   

5. Change U(S)ART Support in Arduino IDE

   Click Tools -> U(S)ART Support -> Enabled (generic 'Serial')

   
   

6. Change Upload Method in Arduino IDE

   Click Tools -> Upload method -> STM32CubeProgrammer (SWD)

   
   

7. Install Library in Arduino IDE

   Download all the library zip files. Then paste it in the: C:\Users\Computer_Username\Documents\Arduino\libraries

   
   

8. Before uploading the program please click: Verify.
   
   

9. If there is no error in the program code, the next step is to use the STM32 programming tool according to the procedure. Then click: Upload.
   
   

10. If there is still a problem when uploading the program, then try checking the driver / port / programmer tool / others section.

ST-Link/V2 Setup

Notes:

• The JTAG or Serial Cable Debugging (SWD) interface module is basically used to communicate with the STM32 board. • You can see the wiring between the ST-Link/V2 and the STM32 board in the picture above. • To upload the program, besides using the ST-Link/V2, you can also use other programming tools such as: CP2102 USB, CH340 USB, PL2303 USB, or with FTDI USB. • Based on experience, I admit that using the ST-Link/V2 is much better than other programming tools because the process is easier, faster, and more stable.
