-The following figure presents the **uC-Probe** interface that can be used for monitoring and controlling the operation of the **EVAL-ADF4001SD1Z** evaluation board. +===== Software Project Setup ===== 
- +{{page>​import_workspace}}
-{{ :​resources:​fpga:​altera:​bemicro:​adf4001interface.png?​700 }} +
- +
-**Section A** allows for the communication with the board to be activated / deactivated by toggling the //ON/OFF// switch. The //​Activity//​ LED turns green when the communication is active. Before pressing the //ON/OFF// switch, make sure you select the desired //Device Initialization Procedure//​. If the //ON/OFF// switch is set to ON and the //​Activity//​ LED is BLACK it means that there is a communication problem with the board. See the **Troubleshooting** section for indications on how to fix the communication problems. +
-The //Error// LED will indicate that the data received on the SDO pin is different than data sent. If the //Function Latch// or //​Initialization Latch// is written, with a different //MUXOUT// value than 6, this LED will be activated. To reset the LED, the board must be deactivated and reactivated,​ case in which the //​Initialization procedure// will set //MUXOUT// to 6. +
- +
-**Sections B to E** allow for configuration of each latch on the **ADF4001**. +
- +
-**Section B** allows for the configuration of the //Reference Counter Latch//. The //LDP// switch will toggle on or off the //Lock Detect Precision// bits. The //TBS// and //ABW// sliders will configure the //Test Mode Bits// and //Anti Backlash Width// bits respectively. The //14 Bit Reference Counter// allows for the configuration of the counter. The last numerical display will display the resulting value in a decimal format. By toggling the //Write// switch in this section, a single write will be performed on the //Reference Counter Latch// with the programmed value. +
- +
-**Section C** allows for the configuration of the //N Counter Latch//. The //CPG// switch toggles the //CP Gain// bit. The //13 Bit N Counter// allows for the configuration of the N counter. The last numerical display in the row will display the resulting value in a decimal format. By toggling the //Write// switch, a single write will be performed on the //N Counter Latch//, with the value displayed.  +
- +
-**Sections D and E** have the same structure. The difference between these two latches is that when the //​Initialization Latch// is programmed, there is an additional internal reset pulse applied to the //R// and //N// counters. This pulse ensures that the //N counter// is at a load point when the //N counter// data is latched, and the device will begin counting in close phase alignment. +
-//PD2// switch toggles the //Power Down 2// pin. The //CS2// and //CS1// sliders will configure the //Current Setting 2// and //Current Setting 1// bits respectively. The //Timer Counter Control// can be configured through the //TCC// slider. Next, the switches configure the //Fastlock Mode//, //Fastlock Enable//, //CP Three-State//​ and //Phase Detector Polarity// bits. The //MUX// slider allows to select what is to be available on the //MUXOUT// pin. By default, at initialization,​ this has the value 6 set, in order to be able to use this pin as SDO. //PD1// switch allows for setting the //Power Down 1// bits. Lastly, the //CR// switch allows for resetting the //R// and //N// counters. +
- +
-===== Troubleshooting ​===== +
- +
-In case there is a communication problem with the board the follwing actions can be perfomed in order to try to fix the issues: +
-  * Check that the evaluation board is powered as instructed in the board'​s user guide. +
-  * In uC-Probe refresh the symbols file by right-clicking on the **//System Browser//** window and selecting **//Refresh Symbols//​**. +
-  * If the communication problem persists even after performing the previous steps, restart the uC-Probe application and try to run the interface again.+
