STC32G Communication Learning Board

This project uses the STC32G12K128 as the main control MCU to learn the three communication methods commonly used in industry: 485, CAN, and 433.

This project uses the STC32G12K128 as the main control MCU
to learn the three commonly used industrial communication methods of the STC32G: RS485, CAN, and RS433.
To effectively utilize the MCU's I/O ports, all I/O ports have been brought out, allowing it to also be used as a minimum core system board.
The RS485 communication uses the MAX485ESA chip;
the CAN communication uses the CA-IS3050G chip, powered by a Mornsun B0505S-1WR3 isolated power supply;
the RS433 wireless communication uses the VG4142T433N0M1 module from Wojin Technology, powered by an AMS1117-3.3.
For communication with a 5V-powered MCU, an SN74LVC1T45DBVR chip is used for level conversion.
Currently, the PCB, except for the connectors, has been soldered and LED testing has been performed (see attachment).
Further learning of each communication module will follow.

Ingchips player

What is it? It's a development board, an offline programmer, and a gadget. It connects to various peripheral functions of Inchips chips, and with your ideas, it becomes even more fun...

The schematic and PCB
layout were created using LCSC EDA Professional Edition. Software development was
performed
using Ingchips SDK + Keil 5 MDK536. The project file structure


is shown in the figure.
The project consists of a top panel (OLED screen + rotary encoder + buttons) and a bottom panel (ING91682C design).
Main functions include:
1. Real-time clock display;
2. Offline programming of Ingchips series chips' built-in flash; 3. Offline
erasing of Ingchips series chips' built-in flash;
4. File management;
5. BLE FOTA upgrade.
Important considerations for
PCB layout: Ensure antenna matching is close to the chip. The DC-DC converter's ground (AVSS) should be connected to the chip's ground via a 0-ohm resistor. Inductor parameters for the DC-DC converter: The official recommendation is 4.7uH; in practice, a larger inductor results in lower ripple. Inductors from 4.7uH to 22uH are acceptable. Maximum ESR is 500mohm, and current is greater than 10mA. For DC-DC related pins: VD, VX, and DVSS, keep traces as short and close to the chip as possible.
