neoPLC UC – Fast, Arduino-compatible Microcontroller with Built-in BLE

// *************** Serial communication with the computer **************

// print text or numbers to the serial terminal
void Serial.print(x);
// print text or numbers to the serial terminal with new line ending
void Serial.println(x);
// print formatted strings to the terminal
void Serial.printf(format,x,...);
// Format Guide
//   %d    - integer
//   %X.Yf - float, X is total minimum precision, Y is precision right of the decimal place
//   %c    - ASCII character
//   \n    - new line
//   \t    - tab

// check number of bytes available in the Serial buffer
int Serial.available();
// read a character from the buffer
char Serial.read();
// write a character to the outgoing buffer
void Serial.write(char c);

// **************************** Bluetooth Low Energy ****************************

// include the neoPLC-BLE library
#include <neoBLE.h>
// create an instance of the BLE UART system
neoBLE ble = neoBLE.uart();

// --- SETUP ---
// initialize the BLE UART service
void ble.begin();

// --- METHODS ---
// check number bytes available
int ble.available();
// read a character from the buffer
char ble.read();
// write a character to the outgoing buffer
void ble.write(char c);

// **************************** Pin Control ****************************

// --- SETUP ---
// initialize a uC pin as input or output
// set the mode of pin 'pin', 'mode' must be either 'INPUT' or 'OUTPUT'
void pinMode(int pin, int mode);

// --- METHODS ---
// read the logical state (0/1 = LOW/HIGH) of input pin 'pin'
bool digitalRead(int pin);
// read the voltage in bits (0-1023) of input pin 'pin'
int analogRead(int pin);

// set the output state 'state' (0/1 = LOW/HIGH) of output pin 'pin'
void digitalWrite(int pin, bool state);
// set the duty cycle 'duty' (0-255) of output pin 'pin'
void analogWrite(int pin, int duty);


// ************************* Timer Interrupts **************************

// include the neoPLC-Timer library
#include <neoTimer.h>

// --- SETUP ---
// create a timer that runs the function 'ISR' every 'delayMicros' microseconds
// up to 6 timers can run simultaneously: each timer needs a unique 'ID', from 0 to 5
void Timer.addTimer(int ID, int delayMicros, [function] ISR);
// create a timer that runs the function 'ISR' every 'delayMillis' milliseconds
// up to 6 timers can run simultaneously: each timer needs a unique 'ID', from 0 to 5
void Timer.addTimerMillis(int ID, int delayMillis, [function] ISR);

// --- METHODS ---
// after a timer has been created, the Timer must be 'started' to begin
void Timer.start();
// after a timer has been started, the Timer can be stopped for convenience or
// to perform timing-critical tasks. It can be restarted with 'start' any time
void Timer.stop();


// ****************** i2c (DDC, 2-wire) communication ******************

// include the neoPLC-BLE library
#include <Wire.h>

// --- SETUP ---
// initialize the i2c library
Wire.begin();

// --- METHODS ---
// request x bytes from IC with address 'addr'
char Wire.requestFrom(int addr, int x);
// check number bytes available
int Wire.available();
// read a character from the buffer
char Wire.read();
// start a transmission with address 'addr'
char Wire.beginTransmission(int addr);
// write a character over i2c
char Wire.write();
// stop transmission and release the bus
char Wire.endTransmission();
