Dependents: Dumb_box_rev2 mbed_GPSproject
iSerial class library can easy be used just by swapping Serial declarations.

Examples
#include "mbed.h" #include "iSerial.h" char s[] = "12345678901234567890123456789012345678901234567890"; int main() { iSerial pc(USBTX,USBRX); char* c = s; while(1) { pc.puts(s); while(pc.readable()){ int ret = pc.getc(); if(ret) *c++ = ret; if(c >= s+sizeof(s)-1) c = s; } wait(1); } }

Comparing speed of ordinary Serial functions
#include "mbed.h" #include "iSerial.h" char s[] = "12345678901234567890123456789012345678901234567890"; // 50 bytes int main() { Timer t; Serial pc(USBTX,USBRX); pc.baud(921600); t.reset(); t.start(); for(int i=0; i<30; i++) { pc.printf(s); wait(0.001); } t.stop(); int t1 = t.read_us(); pc.puts("\n\n\n"); iSerial ipc(USBTX,USBRX,NULL,1000,100); // try NOT to set the buffer over flowed // iSerial ipc(USBTX,USBRX); // set as default = 100, 100 ipc.baud(921600); t.reset(); t.start(); for(int i=0; i<30; i++) { ipc.printf(s); wait(0.001); } t.stop(); int t2 = t.read_us(); ipc.printf("\n\n\nThe time %d, %d [us] was taken.\n", t1, t2); ipc.puts("End."); ipc.flush(); }
