I used CPLD to decode the encoder and used the 485 communication written by the state machine. I encountered a very strange problem. The state machine I wrote is as follows: case(state) Idle: begin ov...
Program function: Initialize the basic parameters of the layout, import the netlist, suitable for the beginning of a new project design. This program is free, welcome to download and use it from the Y...
1. Clearly understand the wiring relationship. Only 4 wires need to be connected. VCC needs to be 5V. 3.3 I have tested and it does not work. The clock and data lines need to use bidir bidirectional l...
HPM6750 has 4 I2Cs, and the HPM6750EVKMINI pin headers lead out 2 I2Cs. There are pull-up resistors on the module side, so I2C0 on the board is used. Unfortunately, the maximum I2C speed of HPM6750 on...
I want to use an optocoupler to isolate the input signal. When VInput is high, the optocoupler is cut off and Voutput outputs high. When VInput is low, the optocoupler is turned on and Voutput outputs...
