Hardware and software compatibility
Every AS50xx demoboard is designed to read or program all kinds of externally connected encoders (e.g. a AS5040
demoboard is capable of programming AS5035, -40, - 43, -45 and - 46 as well). Due to the variety of encoder – demoboard –
software combinations it is advisable to cross-check the setup with application note “AS5000 Hardware / Software
Compatibility”.
