It uses ADC0 to read sensor + +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-ADC0_MQ3/ +cd NuMaker-mbed-ADC0_MQ3 + +``` + +Make shortcut for mbed-os library under the folder NuMaker-mbed-ADC0_MQ3 + +### 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: + +``` +Link: NuMaker-mbed-ADC0_MQ3 +Elf2Bin: NuMaker-mbed-ADC0_MQ3 ++--------------+-------+-------+---------+ +| Module | .text | .data | .bss | ++--------------+-------+-------+---------+ +| Misc | 13333 | 32 | 1061844 | +| features/net | 162 | 16 | 16 | +| hal/common | 2531 | 28 | 148 | +| hal/targets | 6713 | 272 | 104 | +| rtos/rtos | 110 | 4 | 0 | +| rtos/rtx | 6484 | 92 | 8316 | +| Subtotals | 29333 | 444 | 1070428 | ++--------------+-------+-------+---------+ +Allocated Heap: unknown +Allocated Stack: unknown +Total Static RAM memory (data + bss): 1070872 bytes +Total RAM memory (data + bss + heap + stack): 1070872 bytes +Total Flash memory (text + data + misc): 29777 bytes +Image: .\BUILD\NUMAKER_PFM_NUC472\ARM\NuMaker-mbed-ADC0_MQ3.bin + +``` + +### Program your board + +1. Connect your mbed device to the computer over USB. +1. Copy the binary file to the mbed device . +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. + + + +## 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. + + \ No newline at end of file
