- Updated the date in the diligent_jstk_wrapper.vhd file. - Modified the testbench (tb_digilent_jstk2.vhd) to ensure proper data transmission and added a delay to simulate real response time. - Adjusted the digilent_jstk2.vhd file to refine the state machine logic for sending and receiving data, including a new IDLE state and improved handling of the SPI communication. - Enhanced uart_viewer.py to automatically detect the Basys3 board's serial port, improving user experience and reducing configuration errors. - Updated the Vivado project file (diligent_jstk.xpr) to reflect changes in simulation and synthesis settings, ensuring compatibility with the latest design updates.
