LCD interface vhdl
no vote
Digilent's basys2 circuit design and implementation platform includes Xilinx Sparta 3E FPGA, switch, button, indicator light, seven segment display, PS2 and VGA ports. However, it lacks a LCD display that requires a user interface in many applications. Digilent solves this problem by providing serial and parallel interactive external LCD with integrated controller. Although the datasheet and schematic of this LCD screen are currently on their webpage, the lack of any sample code increases the design time. In this document, the program uses UART serial interface (pmodcls) and LCD. In addition, VHDL code is included. The application is written on the LCD screen for "OKAN University" and implemented with a Pacman animation. The connection between FPGA ‟ s JTAG a port and pmodcls J2 connector is performed through a 6-pin connector and cable connector.

I2C verilog code

So this is my second attempt to write the I2C protocol and I have learned a few important things. I believe I am very close to getting this working but have gotten to a point where I have no clue what I may be doing wrong. I have set up 3 indicators to test for slave acknowledgements and 3 indicators to display whether data is above or below nominal or zero. I get data being zero.
