I am trying to use VirtualWire.h with a MX1508 motor driver.
In this test sketch the motor driver works as expected - when the VirtualWire.h and the commands in Setup are inserted the motor driver does not work.
I have determined that it is this line that causes the problem.
vw_setup(2000); // Bits per sec
Can anyone suggest what I might do to correct this.
I am using VirtualWire.h because it is small and seems to be used a lot.
The VirtualWire will be used for 433mhz receiver.
Many thanks in advance.
