Description
Reads a 32-bit signed integer from the serial port
Blocks execution until 4 bytes are available
Reads the bytes, combines them into an int32 and returns it.
Syntax
myInt = readInt32()
Parameters
None
Returns
myInt: a long or int32_t read from the serial port.
Example
% This code reads an incoming int32 from MATLAB
#include "ArCOM.h" // Include ArCOM library
ArCOM serialPort; // Create serial port object
long myInt = 0; // Create an int32
void setup() {
SerialUSB.begin(115200); // Initialize USB serial port
}
void loop() {
myInt = serialPort.readInt32(); // Read an incoming int32
}
