It is recommended to use the Code Composer Studio (CCS) Integrated Development Environment (IDE).
Code Composer Studio is an integrated development environment (IDE) that supports TI's microcontroller and
embedded processor products. Code Composer Studio includes a complete set of tools for developing and
debugging embedded applications. It includes the C/C++ compiler, source editor, project build environment,
debugger, descriptor, and many other features. The IDE provides a single user interface to help you through eve ry
step of the application development process. Familiar tools and interfaces allow users to get started faster th an ever
before. Code Composer Studio combines the benefits of the Eclipse software framework with TI's advanced
embedded debugging capabilities to provide embedded developers with a compelling, feature -rich development
environment.
★
When transmitting, set DIO_7 pin to high level and DIO_13, DIO_14 pins to low level;
★
When receiving, set DIO_7 pin to low level and DIO_13, DIO_14 pins to high level;
★
Before turning off, set DIO_7, DIO_13, DIO_14 pins to low;
The register configuration can be reinitialized when the chip is idle for greater stability.
4.3 Connection instructions to the emulator
TMS, TCK, reset, and ground need to be connected between the emulator and the module, and an additional 3.3V
power supply is required for the emulator;
Use USB to UART module to connect with module, module serial port and IO port are multiplexed, users can set
according to their own needs;
Please note that good grounding is required. When there is a large area of grounding, the power supply ripple is
small. Increase the filter capacitor and try to be close to the VCC and GND pins of the module.
