SerialFlow allows to send and receive packaged arrays of integer values via serial port.
SerialFlow allows to send and receive packaged arrays of integer(short only) values via serial port.
Packet format:
- begin - 0x12
- end - 0x13
- value separator - 0x10
- escape - 0x7D
Simple packet example:
0x12,0x1,0x0,0x10,0x7D,0x12,0x0,0x13
corresponds to: [1,18]
Now handles only short int values. Example:
#include "mbed.h" #include "SerialFlow.h" SerialFlow pc(USBTX, USBRX); AnalogIn gyro_x(p17); // data from gyro x axis AnalogIn gyro_y(p18); // data from gyro y axis int main(){ // two short values pc.setPacketFormat(SerialFlow::COMPLEX_1, 2, 2); while(1){ pc.setPacketValue((short)(gyro_x*1023.0)); pc.setPacketValue((short)(gyro_y*1023.0)); pc.sendPacket(); wait(0.01); } }
On the PC side you can use this program to catch data flows: http://www.poprobot.ru/files/sfmonitor_0.9.zip
