It needs run with some NuMaker-PFM-NUC472 boards, it includes the application of Modbus protocol and RS485 port. -Please refer to the documents on the website https://github.com/OpenNuvoton/NuMaker_NuWicam_Samples/ for more details - -Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli). - -## Get the example application! - -Ontain the mbed-OS library from Windows command prompt - -git clone https://github.com/ARMmbed/mbed-os - - -From the command line of Git Bash, for example: - -``` -hg clone https://developer.mbed.org/teams/Nuvoton/code/NuMaker-mbed-modbus-sample/ -cd NuMaker-mbed-modbus-sample - -``` - -Make shortcut for mbed-os, modbus and nvt_rs485 libraries within the folder NuMaker-mbed-modbus-sample - -### Now compile - -Invoke `mbed compile` specifying the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5: - -``` -mbed compile -m NUMAKER_PFM_NUC472 -t ARM -``` - -Your PC may take a few minutes to compile your code.

Start uVision. -1. Import the uVision project generated earlier. -1. Compile your application and generate an `.axf` file. -1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger). -1. Set breakpoints and start a debug session. - - - -## Troubleshooting - -1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9` - - ``` - mbed --version - ``` - - If not, you can update it easily: - - ``` - pip install mbed-cli --upgrade - ``` - -2. If using Keil MDK, make sure you have a license installed.
