MSP430 and a HC-SR04 ultrasonic ranging module


Juan Ignacio writes:

A while back I bought an HC-SR04. It sat in a box until yesterday when I tried to use it with an MSP430G2553 but unfortunately it wasn’t working. I used Energia to program the Launchpad but I wasn’t getting any response from the device. I hooked up my Logic analyzer to see what was going on and the trigger pulse (channel 1) is there but the device will produce essentially the same echo (channel 0), regardless of whether I put an object in front of the module or not. It wasn’t working.
