ECG amplifier board and PCB in altium designer format USB Interface, PIC18F4550 Microcontroller, Right-Leg Drive Circuit and Ready for Optical Isolation. Operates with 2 x 9 V batteries. Important: Do not use this circuit with any other DC or A

基于Proteus的hid usb仿真，用的是pic18f2550芯片，实现A/D数据2路采集，然后通过USB传输到PC中，没有上位机程序-Proteus hid usb-based simulation, using a pic18f2550 chip, to achieve A/D data 2-way acquisition, and then transferred to the PC via USB, there is no host computer program

VC++ 和 AVR之间的USB通信，有源代码的-VC++ and the USB communication between the AVR, active code

Simple communication with USB with proteus!
