CMD_xpci3xxx_Read32DigitalInputs

#define CMD_xpci3xxx_Read32DigitalInputs   _IOR(xpci3xxx_MAGIC, 60,long)

Read the digital input register of the board.

The input range of the channels set to "1" is within the high voltage range (See chapter 4 "Limit values" of the technical manual of the board concerned). The input range of the channels set to "1" is within the low voltage range (See chapter 4 "Limit values" of the technical manual of the board concerned).

Parameters

[out]

uint32_t

*arg Values of the digital input

arg contains the value of the TTL and the 24V inputs (if the board supports them)

• The values for the TTL are encoded in the 4 higher bytes (mask 0xFFFF0000)
• The values for the 24V are encoded in the lower byte (mask 0x0000000F)

Return values

0	: OK
1	: Internal error
