Is there sample code of this implementation
Hello All,
I need a constant ADC running in the background. The FastAnalogIn seems like it will do the trick, but I keep getting a variety of errors.
Does someone have a working code example, or an example that I could look through?
Thanks

Hey,
What kind of errors are you getting? I currently don't have a real HelloWorld program for it, since it should be pretty much drop-in replacement. But this one I still had in my workspace, I used it when developing the lib:
#include "mbed.h" #include "FastAnalogIn.h" DigitalOut myled(LED1); FastAnalogIn ain(p20, true); FastAnalogIn ain2(p19, false); Timer timer; int main() { volatile float val[1000]; wait(1); printf("\n\r"); timer.reset(); timer.start(); for (int i=0; i<1000; i++) val[i]=ain.read_u16(); timer.stop(); printf("Took %dns per conversion\n\r", timer.read_us()); ain.disable(); timer.reset(); timer.start(); for (int i=0; i<1000; i++) val[i]=ain; timer.stop(); printf("Took %dns per conversion\n\r", timer.read_us()); ain2.enable(); timer.reset(); timer.start(); for (int i=0; i<1000; i++) val[i]=ain; timer.stop(); printf("Took %dns per conversion\n\r", timer.read_us()); printf("Start\n\r"); ain2.disable(); while(1) { myled = 1; wait(0.2); myled = 0; wait(0.2); int value = ain.read_u16(); printf("%d\n\r",value); } }
Main question is which errors you are getting :)
