My project need to control 3 motors and keep track of their positions. I am aware that FTM1 and FTM2 are the only modules that are capable of reading quadrature input. But is it like PWM generation using the FTM where each model has 4 channel pairs and each pair can handle one quadrature pair, giving it 8 total? Or can module only handle one quadrature pair, making it only two total?
I am working with the model based design toolbox and the quadrature decoder block seem to suggest it is the second.
Hi Ray Wu,
S32K144 has only 2 quadrature decoders, one for FTM1 and one for FTM2. Each FTM has one counter, so you can't use more than one quadrature decoder per FTM.
Best regards,
Adrian.
