You can find updated version of documentation on my site​ [PCF8591](https://www.mischianti.org/2019/01/03/pcf8591-i2c-analog-i-o-expander/)
Library to use i2c analog IC with arduino and esp8266. Can read analog value and write analog value with only 2 wire (perfect for ESP-01).
Tutorial:
To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder PCF8591. Check that the PCF8591 folder contains `PCF8591\\.cpp` and `PCF8591.h`. Place the DHT library folder your `<arduinosketchfolder>/libraries/` folder. You may need to create the libraries subfolder if its your first library. Restart the IDE.
# Reef complete PCF8591 Analog input and analog output to digital converter with i2c bus.
I try to simplify the use of this IC, with a minimal set of operation.
Constructor:
you must pas the address of i2c (to check the adress use this guide [I2cScanner](https://playground.arduino.cc/Main/I2cScanner))
```cpp
PCF8591(uint8_t address);
```
for esp8266 if you want specify SDA e SCL pin use this:
```cpp
PCF8591(uint8_t address, uint8_t sda, uint8_t scl);
```
then IC as you can see in the image have 4 analog input and 1 analog output:
![PCF8591 schema](https://github.com/xreef/PCF8591_library/blob/master/resources/PCF8591-Pin-Outs.png)
So to read all analog input in one trasmission you can do (the value is from 0 to 255):
```cpp
PCF8591::AnalogInput ai = pcf8591.analogReadAll();
Serial.print(ai.ain0);
Serial.print(" - ");
Serial.print(ai.ain1);
Serial.print(" - ");
Serial.print(ai.ain2);
Serial.print(" - ");
Serial.println(ai.ain3);
```
if you want read a single analog input or channel:
```cpp
int ana = pcf8591.analogRead(AIN0); // read analog 0
```
This IC have multiple type of read and you can use Analog input or analog channel (when you use single read analog input and channel are the same:
![Channel selection](https://github.com/xreef/PCF8591_library/blob/master/resources/channel_selection.PNG)
For example to read the value of channel 0 in Two differential input you must do:
```cpp
int ana = pcf8591.analogRead(CHANNEL0, TWO_DIFFERENTIAL_INPUT); // read analog 0
```
If you want write an analog value you must do (the value is from 0 to 255):
```cpp
pcf8591.analogWrite(128);
```
Additional feature is to read a write voltage:
For the calculation of voltage you must pass some parameter:
- microcontrollerReferenceVoltage: get voltage from microcontroller voltage (only AVR no esp8266 for esp 3.3v fixed)
- referenceVoltage: if microcontrollerReferenceVoltage false take this value
The command are:
```cpp
void voltageWrite(float value, bool microcontrollerReferenceVoltage = true, float referenceVoltage = 5.0);
float voltageRead(uint8_t analogPin, bool microcontrollerReferenceVoltage = true, float referenceVoltage = 5.0);
```
An examples is:
```cpp
pcf8591.voltageWrite(2.7); // 2.7Volts output
delay(3000);
float ana0V = pcf8591.voltageRead(AIN0); // Read voltage from analog 0
Serial.println(ana0V);
```
For the examples I use this wire schema on breadboard:
![Breadboard](https://github.com/xreef/PCF8591_library/blob/master/resources/simpleschema_bb.png)
