2:ea05f8a719a9 | 2 | # Getting started with NuMaker-mbed-modbus-sample on mbed OS |
shliu1 |
2:ea05f8a719a9 | 3 | |
shliu1 |
2:ea05f8a719a9 | 4 | The code works on an mbed OS platform. It needs run with some NuMaker-PFM-NUC472 boards, it includes the application of Modbus protocol and RS485 port. |
shliu1 |
2:ea05f8a719a9 | 5 | Please refer to the documents on the website https://github.com/OpenNuvoton/NuMaker_NuWicam_Samples/ for more details |
shliu1 |
2:ea05f8a719a9 | 6 | |
shliu1 |
2:ea05f8a719a9 | 7 | Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli). |
shliu1 |
2:ea05f8a719a9 | 8 | |
shliu1 |
2:ea05f8a719a9 | 9 | ## Get the example application! |
shliu1 |
2:ea05f8a719a9 | 10 | |
shliu1 |
2:ea05f8a719a9 | 11 | Ontain the mbed-OS library from Windows command prompt |

shliu1 |
2:ea05f8a719a9 | 25 | |
shliu1 |
2:ea05f8a719a9 | 26 | ### Now compile |
shliu1 |
2:ea05f8a719a9 | 27 | |
shliu1 |
2:ea05f8a719a9 | 28 | Invoke `mbed compile` specifying the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5: |
shliu1 |
2:ea05f8a719a9 | 29 | |
shliu1 |
2:ea05f8a719a9 | 30 | ``` |
shliu1 |
2:ea05f8a719a9 | 31 | mbed compile -m NUMAKER_PFM_NUC472 -t ARM |
shliu1 |
2:ea05f8a719a9 | 32 | ``` |
shliu1 |
2:ea05f8a719a9 | 33 | |
shliu1 |
2:ea05f8a719a9 | 34 | Your PC may take a few minutes to compile your code. At the end you should get the following result: |

2:ea05f8a719a9 | 65 | ## Export the project to Keil MDK and debug your application |
shliu1 |
2:ea05f8a719a9 | 66 | |
shliu1 |
2:ea05f8a719a9 | 67 | From the command line, run the following command: |
shliu1 |
2:ea05f8a719a9 | 68 | |
shliu1 |
2:ea05f8a719a9 | 69 | ``` |
shliu1 |
2:ea05f8a719a9 | 70 | mbed export -m NUMAKER_PFM_NUC472 -i uvision |
shliu1 |
2:ea05f8a719a9 | 71 | ``` |
shliu1 |
2:ea05f8a719a9 | 72 | |
shliu1 |
2:ea05f8a719a9 | 73 | To debug the application: |
shliu1 |
2:ea05f8a719a9 | 74 | |
shliu1 |
2:ea05f8a719a9 | 75 | 1. Start uVision. |

2:ea05f8a719a9 | 83 | ## Troubleshooting |
shliu1 |
2:ea05f8a719a9 | 84 | |
shliu1 |
2:ea05f8a719a9 | 85 | 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9` |
shliu1 |
2:ea05f8a719a9 | 86 | |
shliu1 |
2:ea05f8a719a9 | 87 | ``` |
shliu1 |
2:ea05f8a719a9 | 88 | mbed --version |
shliu1 |
2:ea05f8a719a9 | 89 | ``` |
shliu1 |
2:ea05f8a719a9 | 90 | |
shliu1 |
2:ea05f8a719a9 | 91 | If not, you can update it easily: |
shliu1 |
2:ea05f8a719a9 | 92 | |
shliu1 |
2:ea05f8a719a9 | 93 | ``` |
shliu1 |
2:ea05f8a719a9 | 94 | pip install mbed-cli --upgrade |
shliu1 |
2:ea05f8a719a9 | 95 | ``` |
shliu1 |
2:ea05f8a719a9 | 96 | |
shliu1 |
2:ea05f8a719a9 | 97 | 2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32KB restriction on code size. |
