niDigital_WriteSequencerRegister

Writes a value to a pattern sequencer register. Use pattern sequencer registers to pass numeric values between the pattern sequencer and a runtime test program.

C Function Prototype: ViStatus niDigital_WriteSequencerRegister (ViSession vi, ViConstString reg, ViInt32 value)

Parameter	Description
vi	The specified instrument session the niDigital_init or niDigital_InitWithOptions function returns.
reg	The sequencer register you want to write to. - NIDIGITAL_VAL_SEQUENCER_REGISTER0 ("reg0"): Writes sequencer register 0. - NIDIGITAL_VAL_SEQUENCER_REGISTER1 ("reg1"): Writes sequencer register 1. - NIDIGITAL_VAL_SEQUENCER_REGISTER2 ("reg2"): Writes sequencer register 2. - NIDIGITAL_VAL_SEQUENCER_REGISTER3 ("reg3"): Writes sequencer register 3. - NIDIGITAL_VAL_SEQUENCER_REGISTER4 ("reg4"): Writes sequencer register 4. - NIDIGITAL_VAL_SEQUENCER_REGISTER5 ("reg5"): Writes sequencer register 5. - NIDIGITAL_VAL_SEQUENCER_REGISTER6 ("reg6"): Writes sequencer register 6. - NIDIGITAL_VAL_SEQUENCER_REGISTER7 ("reg7"): Writes sequencer register 7. - NIDIGITAL_VAL_SEQUENCER_REGISTER8 ("reg8"): Writes sequencer register 8. - NIDIGITAL_VAL_SEQUENCER_REGISTER9 ("reg9"): Writes sequencer register 9. - NIDIGITAL_VAL_SEQUENCER_REGISTER10 ("reg10"): Writes sequencer register 10. - NIDIGITAL_VAL_SEQUENCER_REGISTER11 ("reg11"): Writes sequencer register 11. - NIDIGITAL_VAL_SEQUENCER_REGISTER12 ("reg12"): Writes sequencer register 12. - NIDIGITAL_VAL_SEQUENCER_REGISTER13 ("reg13"): Writes sequencer register 13. - NIDIGITAL_VAL_SEQUENCER_REGISTER14 ("reg14"): Writes sequencer register 14. - NIDIGITAL_VAL_SEQUENCER_REGISTER15 ("reg15"): Writes sequencer register 15.
value	The value you want to write to the register.

Note These defined values are currently not supported for gRPC, instead pass the raw values specified alongside, directly.

Return value: Reports the status of the operation.

niDigital_ReadSequencerRegister

Reads the value of a pattern sequencer register. Use pattern sequencer registers to pass numeric values between the pattern sequencer and a runtime test program. For example, you can use this function to read a register modified by the write_reg opcode during a pattern burst.

C Function Prototype: ViStatus niDigital_ReadSequencerRegister (ViSession vi, ViConstString reg, ViInt32* value)

Parameter	Description
vi	The specified instrument session the niDigital_init or niDigital_InitWithOptions function returns.
reg	The sequencer register to read from. - NIDIGITAL_VAL_SEQUENCER_REGISTER0 ("reg0"): Reads sequencer register 0. - NIDIGITAL_VAL_SEQUENCER_REGISTER1 ("reg1"): Reads sequencer register 1. - NIDIGITAL_VAL_SEQUENCER_REGISTER2 ("reg2"): Reads sequencer register 2. - NIDIGITAL_VAL_SEQUENCER_REGISTER3 ("reg3"): Reads sequencer register 3. - NIDIGITAL_VAL_SEQUENCER_REGISTER4 ("reg4"): Reads sequencer register 4. - NIDIGITAL_VAL_SEQUENCER_REGISTER5 ("reg5"): Reads sequencer register 5. - NIDIGITAL_VAL_SEQUENCER_REGISTER6 ("reg6"): Reads sequencer register 6. - NIDIGITAL_VAL_SEQUENCER_REGISTER7 ("reg7"): Reads sequencer register 7. - NIDIGITAL_VAL_SEQUENCER_REGISTER8 ("reg8"): Reads sequencer register 8. - NIDIGITAL_VAL_SEQUENCER_REGISTER9 ("reg9"): Reads sequencer register 9. - NIDIGITAL_VAL_SEQUENCER_REGISTER10 ("reg10"): Reads sequencer register 10. - NIDIGITAL_VAL_SEQUENCER_REGISTER11 ("reg11"): Reads sequencer register 11. - NIDIGITAL_VAL_SEQUENCER_REGISTER12 ("reg12"): Reads sequencer register 12. - NIDIGITAL_VAL_SEQUENCER_REGISTER13 ("reg13"): Reads sequencer register 13. - NIDIGITAL_VAL_SEQUENCER_REGISTER14 ("reg14"): Reads sequencer register 14. - NIDIGITAL_VAL_SEQUENCER_REGISTER15 ("reg15"): Reads sequencer register 15.
value	Value read from the sequencer register.

Note These defined values are currently not supported for gRPC, instead pass the raw values specified alongside, directly.

Return value: Reports the status of the operation.
