Description
Reads an 8-bit signed integer from the serial port
Blocks execution until 1 byte is available
Reads the byte, converts it into an unsigned int8 and returns it.
Syntax
myInt = readInt8()
Parameters
None
Returns
myInt: a int8_t read from the serial port.
Example
% This code reads an incoming int8 from MATLAB
#include "ArCOM.h" // Include ArCOM library
ArCOM serialPort; // Create serial port object
int8_t myInt = 0; // Create an int8
void setup() {
SerialUSB.begin(115200); // Initialize USB serial port
}
void loop() {
myInt = serialPort.readInt8(); // Read an incoming int8
}
