Serial acquisition software

AS is a serial acquisition software allowing to display up to 8 curves simultaneously. It uses COM ports to receive data. It is possible to save the received data. Two backup modes are possible. The first being a manual backup. The other allows a backup according to the achievement of a number of acquisitions made.

When data is received, a time tag is associated with it. When saving data, the time tag is kept with the data.

How it work

Data must be received in a specific sequence. Take for example the case where the transmitter is a microcontroller (µC). The µC first sends a character between a and h inclusively, then it sends the data in float format.

Example of use in Arduino language:

x: Any variable

Serial. println("a");
Serial.println(x,8);

The letter a is associated with the data that follows it. The software will form a curve using all the data associated with a.

Example of code with an Arduino environment

float t=0;
float f=0;
int vit=100;

void setup() {
Serial.begin(9600);
}

void loop() {

t=t+0.1;
f=sin(t);
Serial.println("a");
Serial.println(f,8);

delay(vit);

f=cos(t+1);
Serial.println("b");
Serial.println(f,8);

delay(vit);
}
