能不能推荐一款电机控制的MCU,能正交解码,脉冲计数,运算能力强 .用于医疗设备?
     现采用MC56F827 芯片控制空心杯直流电机,电机的编码器输出A和B相脉冲,相位差90度,MC56F827如何正交解码?Timer如何脉冲计数,进行精确定位?有电路图和程序吗?

Hi, Lili

I suggest you use MC56F84xxx or MC56F83xxx for example MC56F84789, which has 2 eFlexPWM modules, 2 quadTimer modules.
The tools for DSC is CodeWarrior for mcu ver11.x, this is the link:

The debug device is USBTAP, this is the link:

You can order the EVM board for MC56F84xxx, the link is:

The power stage board is:

For the encoder, pls refer to an4813.pdf:
https://www.nxp.com/design/development-boards/tower-development-boards/peripheral-modules/low-voltag...

The KV family is an option, the FTM modules can  generate PWM signal and function as decoder for example KV11, KV31.
