I have designed a circuit using a Picaxe18X to display 3 digits of data on 7-segment LEDs using the Cmos 4553 3-digit counter as the LED interface.
When simulating - the error
"DSIM model CMOS.DLL failed to authorise - Product key not found"
occurs and simulation is aborted.
When attempting to do a 'readadc/readadc10' from port 7 the simulator gives
"access violation in module AXEVSM.DLL" message.
Also with port3 not connected and reading port2 the error message
"Vin not connected to an analog net-results will be invalid" U1ADC3 appears
and with port2 not...
