I am very newbie to uc and general programming, yet I have this task to get done, and I am hoping this community will help me. Please all, come to my aid.
1. The current status of the project is a custom board with AT32UC3A1512 uc. The board specific is for some radar project, and in the project the uc process the acquired data from antennas and send them over (wireless) Zigbee connection to STK600 with another AT32UC3A1512 uc which connects to MATLAB running on a PC.
2. It is now desired to eliminate the Zigbee connection, and instead of sending the acquired data to a PC (with MATLAB), the data should be logged into some SD card which a RPi 3 can easily do.
I need help in interpreting the current codes (in C) that I have for the current status of the project, and help with changing these codes around for communicating with the RPi.
Note- connection to Zigbee module from the radar board/device is through SPI
This connection is still available to connect to the RPi, while another UART is additionally available too.
PS- I have a very lengthy code of about 3000 lines. Pasting them here may be disorderly. Please find in the attachment. A picture of the custom board is as well shown (without the UART connections anyway)
