Device Settings API

The Device Settings API allows for software-based control of some signals and voltage and current on the FMC port, as well as temperature control through a fan that can be connected to the two-pin connector (Molex 53398-0271) at JP1.

The following example sets VADJ on the FMC port to 3.3V and sets FMC to draw from FMC_VADJ_VOLTAGE instead of IPMI EEPROM. This sets the FMC Vadj voltage to 3.3V. Note that the resolution on FMC1_VADJ_VOLTAGE does not allow for single-bit precision on the voltage division, such as 331 instead of 330. Consult your device’s User’s Manual for details on valid settings.

To change the settings on your FrontPanel Device Settings API-enabled device, it is recommended that you first retrieve the existing settings from the board, then modify them using the SetInt method. It is a good idea to verify that the settings are correct at this point. You can then load the settings to the board by saving the settings using the Save method. Note that some settings will not take effect until the board is power cycled.

C/C++

okCFrontPanel dev; okCDeviceSettings settings; UINT32 voltage; UINT32 en; UINT32 mode; // Populate DeviceSettings struct dev.OpenBySerial(); dev.GetDeviceSettings(settings); // Adjust settings settings.SetInt("FMC1_VADJ_VOLTAGE", 330); settings.SetInt("FMC1_VADJ_ENABLE", 1); settings.SetInt("FMC1_VADJ_MODE", 3); // Confirm settings settings.GetInt("FMC1_VADJ_VOLTAGE", &voltage); settings.GetInt("FMC1_VADJ_ENABLE", &en); settings.GetInt("FMC1_VADJ_MODE", &mode); // Save settings to the device settings.Save();
