Have the .hex files been compiled/modified to use the 4 pin ultrasonic modules (DYP-ME007V1 or HC-SR04) instead of the 3 pin module
TS601P01 as specified by the designer Terry Hinrich?
Examination of the .c file suggests the code only supports the 3 pin module.
I am new to pic programming, so apologise for any stupid mistakes.
