I'm porting a Python app from libphiget21 to libphidget22 and, if possible, would like to continue to operate with the native 10-bit integer input (right?) provided by my single USB-connected Interface Kit 1203_2 ver. 204 analog inputs. Is there perhaps an API hidden below the onVoltageChange() or g...

hang in pthread_join subsequent to Python CPhidget_close

Python Phidget application hang in pthread_join called from CPhidget_close. There appears to be a problem with InterfaceKit closePhidget() when using pure time-interval-based analog input interrupt-driven sampling: d.setDataRate(i, 256) d.setSensorChangeTrigger(i, 0) The data sampling works fine. Th...
