RF430FRL152H: Can the Infinite sampling mode be automatically initialized after power-on?

Hi,

I am not aware of a function that is executed when the device is powered up, which the user has access to. Normally the device will only execute the ROM code until it receives a command. 

I will check if there is any workaround to manage setting the start bit after power up and will come back to you the next days.

Hi,

I think I found a solution to start the sample process immediate when the RF430FRL152H is powered up.

From your previous post I see that you are using the digital sensor. The DigitalSensorInit() subroutine is executed at power up. I added code to set the Start bit there. Unfortunately that did not start the measurement. There is an internal variable of the ROM code that needs to be set in addition to get the measurement started. Here is my code that I have added to the DigitalSensorInit() subroutine:

    unsigned int * GeneralControlReg = (unsigned int *)0xF868;
    unsigned char * Check_Conversion = (unsigned char *) 0x1CF1;
    
    *GeneralControlReg |= (unsigned int)BIT0;
    *Check_Conversion = 1;

I defined two pointers, one that points to the General Control Register and one to point to an internal variable of the ROM code. In the General Control Register the Start bit is set and the ROM variable is set to 1.

Please try this out and let me know if this will work for you.

Hi,

I tried it, it seems to be feasible, but I encountered some problems, sometimes the status register will return 0x0b, I am confirming whether it is a code problem in other parts.
