TPMS code transplantation

[guwenlong_l]

I'm currently designing the TPMS project. The chip model I used is FXTH87EH11.

I now have a set of FXTH870911 program code. 

I want to port the program running on FXTH870911 to FXTH87EH11.

What do I need to do?

What exactly is to be done?

What configuration parameters need to be changed?

Hi,

The FXTH870911 code is directly compatible with the FXTH87EH11 device. The only thing to update in the code is the pressure and acceleration thresholds, in counts, if any. The two families have different pressure and acceleration transfer functions, meaning that for a given pressure in kPa or acceleration in g, the reading and compensation functions will return a different number of counts. So if your application uses some thresholds for pressure and acceleration in the code, the values of the thresholds must be updated to match the FXTH87EH11 pressure and acceleration transfer functions.

Best regards,

Tomas
