Microcontroller learning board based on STM32F103C8T6+712476A

Overview

This development board is powered by USB. The computer provides 5V voltage to the development board. The step-down chip reduces the 5V to 3.3V. At the same time, decoupling capacitors are added at both ends of the input and output. The large capacitor filters out high-frequency clutter, and the small capacitor filters out high-frequency clutter. Remove low frequency clutter. The main control chip is STM32F103C8T6. Its minimum system consists of a crystal oscillator circuit, a power circuit, a burning program port (SWD), and a reset circuit. In the crystal oscillator circuit, two crystal oscillators of 8MHZ and 32.768KHZ are selected, with two parallel capacitors of 20pF and 10pF respectively (this can match the crystal oscillator itself). In the reset circuit, after pressing the button, a low level will be generated, causing the program running pointer to point to the original position. This development board is also equipped with an OLED interface, two independently controlled LEDs, three independent buttons, and a series of expansion ports for learning.

Why must the DSP simulator be connected to the target system (Target)?
The DSP emulator is different from the MCU. There is no DSP in the emulator. It provides the IEEE standard JTAG port to simulate and debug the DSP. Therefore, the emulator must have a simulation objec
