| 1 | = SetDACFloat = |
| 2 | Set a DAC register to a floating point value. |

| 4 | {{{ |
| 5 | int SetDACFloat(int dev, DACReg reg, float val, int wait); |
| 6 | }}} |
| 7 | |
| 8 | == Parameters == |
| 9 | |
| 10 | * dev - number of DAC card. |
| 11 | * reg - DAC register to set - dacAD5422Status, dacAD5422Data, dacAD5422Control, dacLowWeight, dacMaxOutput, dacOutputRange, dacScaleAssign, dacHighWeight, or dacGrossNet |
| 12 | * val - value to assign to the register |
| 13 | * wait - WAIT_ACK Wait for acknowledgement, NO_WAIT_ACK do not wait for acknowledgement |
| 14 | |
| 15 | == Return Value == |
| 16 | |
| 17 | * Returns the result - OK success (If WAIT_ACK may be TIMEOUT) |
| 18 | |
| 19 | == Remarks == |
| 20 | |
| 21 | The option card must already be opened by calling OpenMnBd(dev) first. If the application is using main board communication events these events may be called during the wait for acknowledgement. |
| 22 | |
| 23 | == Examples == |
| 24 | |
| 25 | {{{ |
| 26 | int dac = 1; // number of dac card - not number of slot |
| 27 | float val = 120.5; |
| 28 | |
| 29 | // This sets the DAC high weight value |
| 30 | if(SetDACFloat(dac, dacHighWeight, val, WAIT_ACK) != OK) |
| 31 | { |
| 32 | DisplayText(0, 0, "SetDACFloat Error"); |
| 33 | } |
