Modify dji OnBoard SDK sample code on STM32 device

I need assistance performing the following tasks: Download and successfully build the DJI Onboard SDK STM32 sample using Keil uVision. Using the TelemetrySample as guidance, create a simple program to get the GPS coordinate from the A3 (instead of the M100 as default in the code), read a simple string from a second UART port, and write the values to a file on an SD card. I am using the hardware STM32F4VE (https://www.amazon.com/gp/product/B071KBZR58/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1).
