# Getting started with NuMaker-mbed-can on mbed OS The code works on an mbed OS platform. It reads the messages from CAN and the one of R/G/B LED will turn on or all turn off. 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-can/ cd NuMaker-mbed-can ``` Make shortcut for mbed-os library within the folder NuMaker-mbed-can ### 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. At the end you should get the following result: ``` +------------------------+-------+-------+---------+ | Module | .text | .data | .bss | +------------------------+-------+-------+---------+ | Misc | 13163 | 44 | 1051800 | | drivers | 1031 | 4 | 28 | | features/FEATURE_LWIP | 162 | 16 | 16 | | hal | 542 | 8 | 0 | | platform | 1569 | 16 | 92 | | rtos | 144 | 8 | 0 | | rtos/rtx | 7418 | 100 | 8396 | | targets/TARGET_NUVOTON | 8276 | 264 | 104 | | Subtotals | 32305 | 460 | 1060436 | +------------------------+-------+-------+---------+ Allocated Heap: unknown Allocated Stack: unknown Total Static RAM memory (data + bss): 1060896 bytes Total RAM memory (data + bss + heap + stack): 1060896 bytes Total Flash memory (text + data + misc): 32765 bytes ``` ### Program your board 1. Connect your mbed device to the computer over USB. 1. Copy the binary file to the mbed device . 1. Press the reset button to start the program. Please refer to the documents at the path https://github.com/OpenNuvoton/NuMaker_NuWicam_Samples/ ## Export the project to Keil MDK and debug your application From the command line, run the following command: ``` mbed export -m NUMAKER_PFM_NUC472 -i uvision ``` To debug the application: 1. 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. ![Image of uVision](img/uvision.png) ## 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. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32KB restriction on code size.
