Once installed on a SPLat controller, the SPice10211 appears as several regular analog and digital I\/O points. The following table shows the mappings for all the I\/O on the board. Numbers in parenthesis are the numeric analog channel numbers used with fAnIn<\/a><\/code> and fAnOut<\/a><\/code>.<\/p>\n\n\n\n

initializing the SPice<\/a> connector<\/h6>\n\n\n\n

Because the pins of the SPice connector, to which the SPice10211 is connected, can be configured for different functions (analog\/digital, input\/output), you need to have some code in your program that configures them to the correct settings for the SPice12011.<\/p>\n\n\n\n

The following section of code should be run by your program just once, at the beginning, before your program attempts to do anything else with the SPice10211.<\/p>\n\n\n\n

         ClrU<\/a>
         setu<\/a>         0,3         ;set spice connector pin 4 as analogue input
         setu         1,3         ;set spice connector pin 5 as analogue input
         setu         2,3         ;set spice connector pin 6 as analogue input
         setu         3,3         ;set spice connector pin 7 as analogue input
         setu         4,4         ;set spice connector pin 8 as analog output
         setu         5,4         ;set spice connector pin 9 as analog output
         SpiceConfigU<\/a>
<\/pre>\n\n\n\n
If you are using a thermistor circuit you will also need to initialize the thermistor drive voltage to the required value with code like this:<\/p>\n\n\n\n
         LoadX<\/a>        XXX
         AnOutZZZ
<\/pre>\n\n\n\n
In this code replace XXX with the Vfeed value required. You will generate this when you work through the thermistor temperature measurement tutorial<\/a>. On the SPice10211 the Vfeed range is 0 to 20V (representing XXX = 0 to 255).<\/p>\n\n\n\n
Note: The maximum Vfeed value you can use is limited by the supply voltage to the board. The Vfeed generator can at most get to about 2V less<\/em> than the supply voltage. Hence, with say a 12V supply you can at best design for a 10V Vfeed (XXX=127). If you are using an unregulated supply you must take into account voltage variations and ripple. With a 24V regulated supply you will be able to use the full Vfeed range up to 20V.<\/p>\n\n\n\n
Replace ZZZ with the analog output pin used for Vfeed (see table above).<\/p>\n\n\n\n
Programming the thermistor inputs<\/h6>\n\n\n\n
If you are using the thermistor temperature measurement feature you must initialize the drive voltage as described above. Thereafter you get a raw reading from the thermistor into X<\/a> using the appropriate Anin instruction in the table above. The thermistor temperature measurement tutorial<\/a> shows you how to convert the raw readings into temperatures.<\/p>\n\n\n\n
After initialization there will be a delay before the Vfeed voltage settles down. Your program should not perform any control action based on a temperature reading for at least 500mS after initialization.<\/p>\n\n\n\n
Note that during debug with SPLat the SPice board may not show up correctly in the I\/O window unless the board has run the initialize code. You can fix this by translating and running the above initialization sequence in the board. Add a line<\/p>\n\n\n\n
a     goto    a<\/pre>\n\n\n\n
at the end to prevent translation and runtime errors.<\/p>\n\n\n\n
Programming the potentiometers<\/h6>\n\n\n\n
The potentiometers simply appear as two analog inputs.<\/p>\n","protected":false},"excerpt":{"rendered":"
