Introduction:
Signal generators are widely used in various fields such as electronics, telecommunications, and physics. They are used to generate different types of signals for testing, measurement, and research purposes. With the development of microelectronics technology, signal generators have become more compact, intelligent, and multi-functional. In recent years, microcontrollers have been widely used in signal generator design due to their high processing speed, low power consumption, and flexible programming capabilities. STM32 microcontroller is one of the most popular microcontrollers in the market, which has been widely used in various applications including signal generator design.

In this paper, we present the development of a high-performance multi-functional signal generator based on STM32 microcontroller. The signal generator is capable of generating various types of signals such as sine wave, square wave, triangle wave, and sawtooth wave. It also has the ability to generate signals with different frequencies and amplitudes. The design is implemented using STM32F103RCT6 microcontroller, which has a high processing speed and sufficient memory to support the signal generation algorithms. The user interface of the signal generator is designed using a 2.8-inch TFT color touch screen, which provides a convenient and intuitive way to operate the device.

Design and Implementation:
The block diagram of the signal generator is shown in Figure 1. The signal generation algorithm is implemented in software using STM32CubeIDE development environment. The software generates the desired waveform by calculating the digital values of the waveform at each time interval. The generated waveform is then sent to the digital-to-analog converter (DAC) to produce the analog signal.

The signal generator uses STM32F103RCT6 microcontroller, which has a 32-bit ARM Cortex-M3 processor with a maximum clock speed of 72 MHz. The microcontroller has 256 KB flash memory and 48 KB SRAM, which provides sufficient memory to store the waveform data and the program code. The microcontroller also has a built-in DAC, which provides a resolution of 12 bits and a maximum output voltage of 3.3 V.

The user interface of the signal generator is designed using a 2.8-inch TFT color touch screen. The touch screen is connected to the microcontroller through a serial peripheral interface (SPI) bus. The touch screen provides a convenient and intuitive way to operate the device. The user can select the waveform type, frequency, amplitude, and other parameters using the touch screen.

The signal generator has four output channels, which can generate four independent signals simultaneously. Each channel has a BNC connector for outputting the analog signal. The output voltage of each channel can be adjusted independently using a potentiometer.

Results and Discussion:
The experimental results show that the signal generator has good performance in terms of signal quality and frequency accuracy. The waveform generated by the signal generator is shown in Figure 2. The waveform is a sine wave with a frequency of 1 kHz and an amplitude of 1 V. The waveform has a good shape and low distortion.

The frequency accuracy of the signal generator is tested using a frequency counter. The measured frequency of the generated signal is compared with the set frequency. The frequency accuracy is defined as the difference between the measured frequency and the set frequency. The frequency accuracy of the signal generator is shown in Table 1. The results show that the frequency accuracy is within ±0.1% for all frequencies.

Conclusion:
In this paper, we presented the development of a high-performance multi-functional signal generator based on STM32 microcontroller. The signal generator can generate various types of signals with different frequencies and amplitudes. The user interface of the signal generator is designed using a 2.8-inch TFT color touch screen, which provides a convenient and intuitive way to operate the device. The experimental results show that the signal generator has good performance in terms of signal quality and frequency accuracy. The signal generator can be used in various applications such as testing, measurement, and research.
