Here is the code, I've tried various registers to no avail, I am able to read all registers:
//Write - simple to validate instructions - fails to write, does not return any errors, the bit pattern on scope looks correct for slave addres, register addres and register data
WriteData[0] = 0x0; // address
WriteData[1] = 0x0; // data
// create script
if (errorCode = ni845xI2cScriptOpen (&ScriptHandle)) return errorCode;
// configure clock rate
if (errorCode = ni845xI2cScriptClockRate (ScriptHandle, ClockRate)) return errorCode;
if (errorCode = ni845xI2cScriptIssueStart (ScriptHandle))return errorCode;
//write 7-bit address and direction bit 0 (write)
if (errorCode = ni845xI2cScriptAddressWrite (ScriptHandle, I2C_SLAVE))return errorCode;
//write array
if (errorCode = ni845xI2cScriptWrite (ScriptHandle, 2, WriteData)) return errorCode;
// issue stop condition
if (errorCode = ni845xI2cScriptIssueStop (ScriptHandle)) return errorCode;
//set delay
if (errorCode = ni845xI2cScriptDelay (ScriptHandle, 5)) return errorCode;
// run the script
if (errorCode = ni845xI2cScriptRun (ScriptHandle, DeviceHandle, 0)) return errorCode;
// close script handle
if (errorCode = ni845xI2cScriptClose (ScriptHandle)) return errorCode;
//Read instructions - works correctly, no issues
// create script
if (errorCode = ni845xI2cScriptOpen (&ScriptHandle)) return errorCode;
// configure clock rate
if (errorCode = ni845xI2cScriptClockRate (ScriptHandle, ClockRate)) return errorCode;
if (errorCode = ni845xI2cScriptIssueStart (ScriptHandle))return errorCode;
//write 7-bit address and direction bit 0 (write)
if (errorCode = ni845xI2cScriptAddressWrite (ScriptHandle, I2C_SLAVE))return errorCode;
//write address to read from
if (errorCode = ni845xI2cScriptWrite (ScriptHandle, WriteSize, WriteData))return errorCode;
//write read location
if (errorCode = ni845xI2cScriptIssueStart (ScriptHandle)) return errorCode;
if (errorCode = ni845xI2cScriptAddressRead (ScriptHandle, I2C_SLAVE)) return errorCode;
if (errorCode = ni845xI2cScriptRead (ScriptHandle, ReadSize, kNi845xI2cNakTrue, &ScriptReadIndex)) return errorCode;
