MKW38A512VFT4 problem

1.Shorten warm-up time，target ：less than 50us

Before sending, there was about 112us of warm-up time,

Before receiving, there was about 190us of warm-up time,

Registers are read-only and cannot be modified,

between receiving and sending,What time can be saved， in order to minimize the switching time. The target receiving and sending hot time is within 50us.

2.Routine for using FEC in FSK/GFSK mode (based on S32DS)

3.Overfrequency:

Main frequency CPU or communication BPS: how much can the limit be reached

Hi, @Song2552049

Sorry for my late reply.

To better understand your question, may I ask more details about the this case?

1.There was about 112us of warm-up time before receiving, there was about 190us of warm-up time. What's the warm-up time do you mean? And how do you get this data(112us and 190us)? Do you measure it by yourself or get this info from our datasheet/user manual or some other documents?

2. Routine for using FEC in FSK/GFSK mode (based on S32DS).

Sorry for your inconvenience. We don't have routine for KW38 based on S32DS, only have SDK based on MCUXpresso. Here is the MCUXpresso SDK Builder link.

3.Overfrequency: Main frequency CPU or communication BPS: how much can the limit be reached.

==> Maximum CPU frequency is 48MHz.

Best regards,

Christine.
