Can I use interrupts while working with the USBSerial?
Hello! I am working with the FRDMKL25Z.
I tryed to use the following code to test if the timer interrupts works when I use the USBSerial class. The result is that ticker locks the code every timer overflows... why does that happen?
#include "mbed.h" #include "USBSerial.h" /*---Classes------*/ DigitalOut myled(LED1); DigitalOut pte1(PTE1); USBSerial pc; Ticker t1; /*---Functions---*/ void SerialCallback(void); void T1Handler(void); int main() { pc.attach(&SerialCallback); t1.attach(&T1Handler,1); while(1) { myled=1; wait(1); myled=0; wait(1); } } void SerialCallback(void){ while(pc.readable()){ pc._putc(pc._getc()); } return; } void T1Handler(void){ pc._putc(0x32); return; }
OF COURSE! you cant use those functions inside an interrupt!!!
