Overview¶
TODO
Prerequisites¶
- It is highly recommended that you run through the PRU_example_CCS_load before starting this example. The hello world example will provide a foundation for PRU code development.
- Download and install Code Composer Studio
- Clone the PRU Software Support Package
$ git clone https://git.ti.com/git/pru-software-support-package/pru-software-support-package.git
