when generating code from Simulink for RaspberryPi 3, the generated code always sets the I2c speed to 100 kHz. The generated code looks like this:

 localDW->obj_gt.BusSpeed = 100000U;
 i2cname = 1;
 MW_I2C_SetBusSpeed(i2cname, localDW->obj_gt.BusSpeed);

Is there any way for Simulink to automatically generate I2C speed different from '100000U'?

Could you set it up from Hardware Implementation pane > Target Hardware Resources > SPI > SPI0 CE0 Bus Speed (kHz)?

Well, I assume that your suggestion is applicable to SPI, not I2C.
