Introduction to UART 0 and USB 2.0:¶

Program downloads require the use of UART 0.

Note: Turn on the switch before use. Slide the POWER switch to the ON position.

If the program utilizes screen functions, power consumption will reach 8-10 watts. If powered solely by the computer's USB port, insufficient power may cause the screen to go black. It is necessary to connect a USB 2.0 port simultaneously for power supply.

If the UART0 connection does not display a serial port number, it may be due to missing serial port drivers. Download the CH341 serial port drivers and retest the connection.

Serial Port Driver for Mac:https://www.wch.cn/downloads/CH34XSER_MAC_ZIP.html

Regarding situations where serial ports remain inaccessible after installing drivers on a Mac, the following settings must be configured on the Mac:¶

After installing the CH341 serial port driver, navigate to System Preferences.Click Login Items & Extensions.

2.Click Driver Extensions.

Click Open, then click Done to save the settings.

USB 2.0:¶

USB 2.0 (Universal Serial Bus 2.0) is a common universal serial interface standard used to connect computers with various peripherals.

Its maximum transfer rate is 480 Mbps (High-Speed mode), representing a significant improvement over USB 1.1. This enables it to meet the data transfer needs of devices such as keyboards, mice, USB flash drives, printers, and webcams. USB 2.0 supports hot-plugging and plug-and-play for ease of use, while also providing 5V power supply (up to 500 mA) to peripherals.

Note: The shipped firmware does not include USB functionality. For those requiring USB features, please refer to our USB functionality course in Lesson 6.

NOTE:The firmware for the C6 module is pre-programmed at the factory and cannot be directly reprogrammed via P4.
