Hi Michael,
Thanks for your helpful directions.
I had followed your approach regarding Clock and TimerJiffyAsync and was
able to compile the TestAcousticRanging appliation. However, when running
I was always getting "-1" as the distance between two motes. On further
inspection I realized that I had forgotten to put PLATFORM_MICAZ in
certain components. I have inserted PLATFORM_MICA2 || PLATFORM_MICAZ in
OutsideRangingSensorM.nc and HPLADCC.nc and now I am getting non negative
numbers as distances though I have yet to verify if the distance
measurements are indeed correct.
Did you manage to check if the distance measurements are working properly?
