Johnson counter
no vote
The so-called Johnson counters, in fact, plainly nothing more than a little water lights complex experiments. Water lights Add a button control, open and close and change the direction of flow of the lamp will be under the control of the keys. This example is a two-way stop control with 4bit Johnson counter intuitive by LED lights In the study panel presentation

FFO-based serial port to send
no vote
The main function of the realization of a serial transmitter, which sends the data is read from the FIFO. That is, as long as there is data in the FIFO, serial transmitter will start to send data out. The serial transmitter consists of three modules. datagene module generates every 1s 16-byte increments of data that will be written fifo232 in case of a 256-byte size The FIFO. Once detected, the FIFO data, uart_ctrl module will be data in the FIFO Read out and sent through the serial port. We can use a serial cable to connect SF-EP1C board and PC, via the serial Are port debugging assistant view the received data is a set of constantly increasing data.

To display the character, you first need to obtain a matrix of data, we try font software PCtoLCD2002 (with There are sets of discs, are also widely available on the Internet under). The font software with 1bit representative color of a pixel, The user can decide which color 1bit data (0 or 1) represented as needed.

Aiming at the needs of video surveillance in China, this paper designs and completes a video surveillance system based on FPGA chip. The system uses Verilog HDL language to describe the whole hardware architecture, which makes the system performance more stable and the operation easier. The system obtains image data through ov7670 camera, introduces FPGA from CMOS image sensor, and writes bus interface to deliver data to NIOS
