u32 PM_GetAmp( PMAmpSwitch* swBuf );
swBuf | The buffer that saves the obtained results of the amp switch settings. |
The PM_RESULT_SUCCESS
return value indicates that the execution of the command has succeeded. The PM_RESULT_ERROR
return value indicates that an error has occurred with the ARM7 processor.
Gets the current settings of the programmable gain amp switch.
The value of the PMAmpSwitch
enumerator type is saved in the swBuf argument and can contain either one of the following values:
PM_AMP_ON |
Amp is ON. |
PM_AMP_OFF |
Amp is OFF. |
This function uses PXI to send the command that performs the corresponding operation in the ARM7 processor. The ARM7 side that receives that command is executed by operating the PMIC. Therefore, this function may not operate promptly after you call it. Before you use this function, initialize the PM library by using the PM_Init()
function. The PM_Init()
function has to be called only once. Also, when you call OS_Init()
, there is no need to call PM_Init()
separately since it is called from within OS_Init()
.)
Note: If PM_RESULT_ERROR
was returned as the return value, it is usually an unrecoverable error. It might be returned when ARM7 is not ready or the variable region was destroyed. If this is returned there may be a problem in the program.
Reads the PMIC register OP_CTL
value.
