  1. I'd like to use Energia with my custom board that has the CC3220MODASF MCU on it. Can someone please provide step-by-step instructions on the steps required to have my custom board show up in the "Boards" in the Energia menu and the required edits to make it usable ? I've done quite a bit of online research and in this forum and found bits and pieces but nothing complete. From this ticket and others I found, putting the pieces together, I believe this is the correct partial course of action: 1. Install the corresponding Launch Pad board in Energia (CC3220SF_LAUNCHXL) --> DONE 2. Go to "....\AppData\Local\Energia15\packages\energia\hardware\cc3220emt\5.6.2" 3. Edit "boards.txt" , copy the entry for the board of interest and replicate for the custom board after renaming , ie: Took this one: CC3220SF-LAUNCHXL.name=CC3220SF-LAUNCHXL (80MHz) CC3220SF-LAUNCHXL.upload.maximum_size=262144 CC3220SF-LAUNCHXL.build.mcu=cortex-m4 CC3220SF-LAUNCHXL.build.f_cpu=80000000L CC3220SF-LAUNCHXL.build.core=cc3220emt CC3220SF-LAUNCHXL.build.variant=CC3220SF_LAUNCHXL CC3220SF-LAUNCHXL.build.ldscript=linker.cmd CC3220SF-LAUNCHXL.build.board=CC3220SF_LAUNCHXL CC3220SF-LAUNCHXL.build.mcu=cortex-m4 CC3220SF-LAUNCHXL.upload.tool=dslite CC3220SF-LAUNCHXL.upload.protocol=dslite and created this one: CC3220SF-LAUNCHXL.name=CC3220SF_CUSTOM_BOARD --> renamed CC3220SF-LAUNCHXL.upload.maximum_size=262144 CC3220SF-LAUNCHXL.build.mcu=cortex-m4 CC3220SF-LAUNCHXL.build.f_cpu=80000000L CC3220SF-LAUNCHXL.build.core=cc3220emt CC3220SF-LAUNCHXL.build.variant=CC3220SF_CUSTOM_BOARD --> renamed CC3220SF-LAUNCHXL.build.ldscript=linker.cmd CC3220SF-LAUNCHXL.build.board=CC3220SF_CUSTOM_BOARD--> renamed CC3220SF-LAUNCHXL.build.mcu=cortex-m4 CC3220SF-LAUNCHXL.upload.tool=dslite CC3220SF-LAUNCHXL.upload.protocol=dslite 5. In the "variants" folder, I created a copy of the "CC3220SF_LAUNCHXL/" and named "CC3220SF_CUSTOM_BOARD" I'm not sure what to do after this step. I know I have to do some pin mapping/edits, but not where where/how. My questions are: A. Are the steps above correct? B. After this, opening up Energia, I know see "CC3220SF_CUSTOM_BOARD" but no longer see "CC3220SF_LAUNCHXL". Why is that? Isn't this supposed to leave CC3220SF_LAUNCHXL and just add "CC3220SF_CUSTOM_BOARD"? C. In the "CC3220SF_CUSTOM_BOARD/" folder, is "pins_energia.h" the only file I need to edit? The current contents are D. There's also the "pins.c" file. It looks like I have to edit that file as well? If so, I'm not sure how to edit these and what keyword I need to use instead of "PIN_FUNC_UNUSED"? The current contents are: E. Can someone explain how the "pins.c" and "pins_energia.h" relate to each other? For example, how does this line in "pins_energia.h": "static const uint8_t RED_LED = 29;" relate to the same pin number in "pins.c" file? Pin 29 in that file shows it's unused: " PIN_FUNC_UNUSED, /* 29 - GPIO_09 */" I'm using: energia-1.8.10E23 and I have the XDS110 standalone programmer, which I plan to use with Energia to program my custom board. Thanks! Berry
