1.2 Software

1.2.1 Development Environment

Customers can use Keil to develop ASR6601. Makefile also can be used for compilation and download. For further details, please refer to ASR6601_Quick Start Guide.

1.2.2 Test Codes

Test codes can be found in the directory of projects\${DEMO_BOARD}\examples\lora\lora_test in SDK. ${DEMO_BOARD} is the corresponding board name. For example, ASR6601SE-EVAL stands for ASR6601SE/SER development board, and ASR6601CB-EVAL stands for ASR6601CB/CBR development board.

1.3 Compilation and Download

Please refer to ASR6601_Quick Start Guide for compilation and download introductions.
