I can't measure several encoders (QEI doesn't wrok).

I want to read several encoders using QEI. I have succeeded to read one encoder, but the program doesn't work when I read two encoders. I use 303k8.

  1. include "mbed.h"
  2. include "QEI.h"

Serial pc(USBTX, USBRX);

QEI wheel1 (D8, A4, NC, 12, QEI::X4_ENCODING);

QEI wheel2 (A7, D12, NC, 12, QEI::X4_ENCODING);

int main() {

while(1){ wait(0.1); pc.printf("1 Pulses is: %i\n", wheel1.getPulses()); pc.printf("2 Pulses is: %i\n", wheel2.getPulses()); }

}

Hi~~ I have the same problem..., do you solve it?
