The essence of I2C bus implementation based on FPGA

The Chinese name of I2C (inter integrated circuit) is "integrated circuit bus", which is a serial synchronous half duplex bus. I2C bus is a simple, bidirectional two-wire synchronous serial bus developed by Philips company. It only needs two wires to convey information between devices connected to the bus. One is data line (SDA) and ...

Binary and gray code conversion

The following is taken from the guide to the design of punctual atomic logic Gray code is a binary cyclic code. The characteristic of gray code is that when changing from a number to an adjacent number, only one data bit jumps. Due to this characteristic, metastability in binary code counting combinational circuit can be avoided. Gray code is ...
