Function Documentation

int gGTICcmd (  gtemHandle  gt, unsigned short  temAddr, unsigned short  opcode )

Sends a dataless command to the GTIC address. Parameters: gt  gtemHandle for TEM temAddr  TEM address of command opcode  opcode of command to send Returns: G_OK on success Sends the dataless command specified by opcode to the GTIC address specified by temAddr.

int gGTICload (  gtemHandle  gt, unsigned short  temAddr, unsigned short  reg, unsigned int  value )

Loads a register with value. Parameters: gt  gtemHandle for TEM temAddr  TEM address of command reg  register of GTIC to load value  32-bit value to load into GTIC register Returns: G_OK on success Loads the GTIC register specified by reg with value

int gGTICread (  gtemHandle  gt, unsigned short  temAddr, unsigned short  reg, unsigned int *  val )

Reads a register returing value in val. Parameters: gt  gtemHandle for TEM temAddr  TEM address of command reg  register of GTIC to read val  pointer to storage to hold the response of the read command Returns: G_OK on success Reads the GTIC register specified by reg. val is filled on return.

int gGTICreadEnv (  gtemHandle  gt, unsigned short  temAddr, unsigned short *  env )

Reads a block of 8 16-bit ADC values for environmental quantities. Parameters: gt  gtemHandle for TEM temAddr  TEM address of command env  pointer to storage to hold 8 * 16-bit environmental quantities Returns: G_OK on success Reads the GTIC ADCS register which returns 8 12-bit environmental ADC values. This function returns the data as 8 16-bit values.
