- Ensure the HiTech tool chain is installed before creating the project. Evaluation version of Hitech Compiler is embedded in Mplab Setup which needs to be installed along with Mplab.
Step 5: Upon selecting the ToolChain, Browse to the project folder and provide the suitable project name and save it. .
Step 6:
Step 7: Click next to proceed as there are no files(.c/.h) to be added at this stage.
Step8: Finally click finish to create the project. Now the project will be created with no initial files.
