Specific LF carrier pattern wake up FXTH87xx

[tedwu1]

I used the TPMS' MCU of FXTH8709. For power saving reason that I want to use specific LF carrier pattern to wake up the MCU instead of continuous carrier. The specific LF carrier pattern is 1000ms on and 100ms off continued. Does anyone know how to setup the register of FXTH8709?

Hi Ted,

Decoding custom patterns requires using the LF block in Direct mode configuration.

More information and code example can be found in sections 3.1.4 and 3.1.5 of the FXTH87EDRM.

Best regards,

Tomas
