ADC0809 Module 8-bit 81 Parallel AD Board Analog to Digital Conversion Program Digital Voltmete
Baby parameters
Module size: 3.4cm*5.2cm;
Supply voltage: 5V;
Module interface description
VCC: positive power supply;
GND: negative power supply
IN0-IN7: 8 analog input ports;
D0-D7: 8-bit data output port;
CLK: ADC0809 clock;
OE: output enable signal, active high;
EOC: conversion end signal, active high;
STR: start conversion signal;
All IO ports are led out, and debugging is more convenient and flexible through the following short-circuit caps:
The J7 potentiometer enables control, the J7 short-circuit cap is inserted, and the potentiometer voltage regulating circuit on the board is connected to the channel IN3;
J8 controls the connection between the positive reference voltage VREF and VCC, select the positive reference potential as 5V, or remove the shorting cap and input the positive reference voltage yourself;
J9 controls the connection between the negative reference voltage VREF- and GND, and selects the negative reference potential as 0V. You can also remove the short-circuit cap and input the negative reference voltage yourself;
J3/J4/J4 select the address of the analog channel input for the flashlight, you can also remove the short-circuit cap and set the channel address through the MCU software;
