Показать описание
This tutorial explains how to construct Displaying message on 16x2 LCD in VHDL and programming it on FPGA kit

EDGE Spartan 7 FPGA Development board is the low cost and feature rich FPGA kit which is upgraded from EDGE Spartan 6 kit. Both EDGE Spartan 6 and Spartan 7 share the same interfaces except FPGA IC. An advantage of EDGE Spartan 7 over Spartan 6 is more logic resources and fully compatible with Vivado design suite.

Its features includes FPGA, SPI FLASH, Wi-Fi, Bluetooth, ADC, DAC, LCD, 7 segment, VGA, PS2, Stereo Jack, buzzer, Push Button, Slide Switch, LED, Temperature Sensor, LDR and UART. The Board also provides additional interface like CMOS Camera and TFT Display at the expansion connectors.

EDGE FPGA kit is ready to use Laboratory kit for ECE Curriculum. It can be useful for developing basic to advanced level digital circuits.

Advantage of EDGE FPGA kit is easy to implement plenty of applications ranging from Wireless control, Image/video Processing, Internet of Things without additional interfaces.

Xilinx offers free WebPACK™ versions of Vivado design suite, so designs can be implemented at no additional cost

Thanks, I used it and the text successfully got printed on the LCD screen although I havent used the spartan FPGA

Your code is a heck of a lot more concise than mine was. I was using a pcf8574at to save wires on the board itself. I had to design and utilize an I2C controller on the RTL level to send address/data onto the pcf8574at slave via SDA. The SDA was then converted to the data field of the LCD. I used 350 or so lines just in my TOP file alone. I was sending RS, RW, and E from the board to the LCD directly. Most of my code was consisting of an FSM I designed. I can share with you all, along with a parts list if you want to try and implement my design for yourself.

Good morning sir, I wrote the verilog code for lcd accessing with edge artix 7 fpga, but characters are not printing on it
