Basic Format of Command String

• The name of command string 1: command parameter@ attribute 1: attribute value@ attribute 2: attribute value … @ attribute n: attribute value;
• The name of command string 2: command parameter@ attribute 1: attribute value@ attribute 2: attribute value … @ attribute n: attribute value;
• The name of command string n: command parameter@ attribute 1: attribute value@ attribute 2: attribute value … @ attribute n: attribute value;

Description

1. It is not case-sensitive;
2. Numerical value support the format of hexadecimal, octal and decimalism;
3. Support multiple statements (depends on model), if multiple statements and attributes on failure, try to using single statement and attribute;
4. Every statement must end with ‘;’；
5. Spaces are supported between names, values, and tags;
   Example：
   “wp@ch:0@addr:10@v:10;” “key: c1;”
   Term： SG – short name of Signal Source

General Command

status
Local?| Query keyboard is locked or not| R| Enum:0/1{unlocked/locked}|
Lock?| Query the lock status of keyboard| R| 8Bytes，64 signed integer, flag bit|

Write Parameter

parameter address
v| Parameter value| W| Value usually measured by the smallest unit

• Example：
  “wp@CH:0@addr:9@v:1000;” – set the frequency of CH1 is 1mHz；

• Note：
  UCI corresponding interface: uci_Write

Read Parameter

parameter address

• Example：
  “rp@CH:0@addr:9;” – read the frequency of CH1；

• Note：
  UCI corresponding interface: uci_Read， corresponding data size are 8 bytes, double types！

Key

Lock?

| Query the lock status of keyboard| ****

R

| Integer<4Bytes>： 0 – unlocked； 1 – locked

• Example：
  • “KEY:c1;” — CH1
  • “KEY:c2;” — CH2
  • “KEY:c2@lock;” — CH2 locked the key
  • “KEY:c2@unlock;” — CH2 unlocked the key
  • “KEY:c2@lock?;” — Query keyboard locked or not
• Note：
  Command with question mark read in uci_Read . The status gets from the interface return value.

Read and Write Configuration File

• Example：
  “dconfig;”

• Note：
  Use the interface uci_Readto read，buffer area size can set as 1024Bytes，the actual of effective data is defined by the interface return value. Use the interface uci_WriteFromFile to write configuration data, which does not recognize the file suffix, it can only recognize command “dconfig;”, write configuration timeout at least 6s.

Capture Screen

{unpacked pixel data/packed pixel data /BMP file data

• Example：
  • “PrtScn:bmp;” — screenshot saved as bmp file data；
  • “PrtScn;” — screenshot saved as pixel file data；
  • “PrtScn:zip;” — screenshot saved as packed pixel file data；
• Note ：
  Use uci_Read to read data，the command has no saved data file, it should return to the specified buffer area of uci_Read . If you want to buffer a local file, please save it by yourself.

1. If use command： “PrtScn;”，buffer area size must be >=391680(480 272 3)，readout is 24bits of pixel data;

2. If use command：“PrtScn:bmp;”，buffer area size must be 480 272 3 + 54 = 391734,that is the size of picture.

3. If use command： “PrtScn:zip;”， buffer area size can set >=391680 (480 272 3 )（maximum data volume）, readout is packed pixel data. And then use the interface：alg_UnCompressPixels_25 to unzipping data.
   Note: uci_Read return value is packed data volume

4. Use the interface uci_ReadToFile to add the command “prtscn:bmp;”, it can save bitmap to disk file.

Write Random Wave File

• Example：
  “WARB@CH:0@MODE:0;” Loading wave file as carrier wave form into to CH1

• Note：
  use the interface uci_WriteFromFileto to write random wave file, timeout set to 1000.

Appendix

Parameter address

Numerical value unit：

• Frequency unit ： μHz， 1mHz° set value 1*1000；
• Voltage unit : μV
• Time unit ： ns（ns、μs、ms、s）, for example 1s return value is 1*1000^3
• Degree unit ：0.01°，phase set to 90°，return value is 90 * 100
• Percent unit 0.01% ，for example duty cycle, return value= input value *100
