Joint_Reset_Register
AI configuration start = 0;
AI configuration end = 1;
10. The function
AI_Scan_Start
selects the scan start event.
Joint_Reset_Register
AI configuration start = 1;
AI_Start_Stop_Select_Register
Start edge = 1;
Start sync = 1;
Joint_Reset_Register
AI configuration start = 0;
AI configuration end = 1;
11. Call the function
AI_End_of_Scan
to select the end of scan event.
Joint_Reset_Register
AI configuration start = 1;
AI_Start_Stop_Select_Register
Stop select = 19;
Stop sync = 1;
Joint_Reset_Register
AI configuration start = 0;
AI configuration end = 1;
12. Same as Step 4.
13. Now start the acquisition with
AI_Start_The_Acquisition
.
AI_Command_1_Register
Convert Pulse = 1;
14. Poll the AI FIFO not empty flag in the AI_Status_1_Register until not
empty and read the ADC FIFO data in the ADC_FIFO_Data_Register.
Do
{
If (AI FIFO not empty) then
read FIFO data;
} while (FIFO not read)
Example 2
Example 2 illustrates the manner in which to program the STC for
scanning.
Acquire 5 scans at a scan interval of 1ms. The scan list contains channels
5, 4, 1, and 0, repectively. The channels are configured as RSE at a gain
