Hello.
I need a QEI peripheral to realize an accurate 32 bit count from a quadrature encoder but my processor LPC11E68 does not have a QEI peripheral. Is this possible with the SCTimer, and if so, how?
I think yes, you can add logical XOR gate , together with SCTIMER to make a quadrature encoder.
There is an application using PLU and SCTIEMR , you can have a look at the theory, replace PLU with XOR gate.
Sorry it is in Chinese, no English version, try translate it into English.
