Embedded / MCU Firmware Modification

This project is to modify firmware for the Texas Instruments TM4C129X ARM Cortex-M4F microcontroller. The firmware needs to run on the following development board. [login to view URL] The task is to take the TivaWare freertos_demo example project and make the following changes to it. The example project can be downloaded at the following link. [login to view URL] The project can be found in the folder \TivaWare_C_Series-2.1.4.178\examples\boards\dk-tm4c129x\freertos_demo Here are the specific tasks. 1) Remove the web server from the lwip_task. Instead, replace it with a task that polls the following URL every 5 seconds. [login to view URL] The task should poll this url and parse the JSON response into a struct object. 2) Replace the spider_task with a different task named gradient_task. The gradient task should draw an image of a color temperature gradient on the screen. Something such as the following. You can just use this exact image, rescale it as needed to get the correct resolution. The image will be replaced with something different at a later time. [login to view URL] Overlayed on top of the gradient/image should be a vertical bar that moves side to side. The gradient_task should check a variable once per second and change the position of the vertical bar along the gradient. This will be tied to the lwip_task and update the position based on the value returned by the server, but don't worry about that for now. You can just program that bar to automatically move back and forth for now to demonstrate that it works. That's it.
