CClientAPI::ReadAnalog

Form
long ReadAnalog(short DeviceType, short Channel, short * pVal)
Return value is ERRCODE value.

Description
Reads the analog input value from ADC board .
DeviceType value is a type of Analog-to-Digital converter
that is installed on the board

DEVICE_TLC2543.

Available values of Channel are:

ANALOG_CHANNEL1
ANALOG_CHANNEL2
ANALOG_CHANNEL3
ANALOG_CHANNEL4
ANALOG_CHANNEL5
ANALOG_CHANNEL6
ANALOG_CHANNEL7
ANALOG_CHANNEL8
ANALOG_CHANNEL9
ANALOG_CHANNEL10
ANALOG_CHANNEL11
ANALOG_CHANNEL12

DEVICE_MAX127, DEVICE_MAX128
Channel defines a number of physical analog input of ADC board.
Available values of Channel are 0,1,2,3,4,5,6, 7.
pVal is a pointer to the variable that receives analog input information.

Example

// Create an object

CClientAPI obj;

short Value;

if ( !obj.InitPort())

{

// Get the analog input value of channel #4

ERRCODE ec=board.ReadAnalog(DEVICE_TLC2543, ANALOG_CHANNEL4, &Value);

if ( !ec )

// Good request

else

// Bad request

}

setbit(P1.3) ;// input or weak pull-up output

sorry

   deviceNumber |= (address >> 8 ) ;

   ec = Transmit( I2C_DEVICE_24CXX | I2C_WRITE | (deviceNumber << 1) );

Please note, you changed the original  source.
It had contained
....

   deviceNumber |= (address >> 8);
   ec = Transmit( I2C_DEVICE_24CXX | I2C_WRITE | (deviceNumber << 1) );
...

If you use 8051/52 development system
you will be able to find EEPROM example under
C:\\bipom\\devtools\\MicroC\\Examples\\8051\\tiny\\eeprom\\24C04 folder.
Please try it.

The following Preprocessor  commands are recognized by the MicroC compiler
if they occur at the beginning of the source file line:  
1)
#error <text>
 Causes  MicroC to  issue  an  error  message  containing   the
specified text, and then terminate.

2)
#message <text>
Outputs an informational message (does not terminate).

For example,
#message "SOME MESSAGE"

Please download the latest release from http://www.bipom.com/software.shtm
This known problem was fixed a few months ago.
Mini-Max/51-C loaders of the new releases were modified to support AT89C51ED2 chip.

Best regards,

68HC12 Development Tools / Re: Running C programs
« on: March 07, 2004, 04:22:00 am »
I guess you have some problems with CSTARTUP files.
In other words, you should  adapt the start-up code for your board.
Please check 6812RLM.ASM, 6812RLP.ASM, and 6812RLS.ASM files
under C:\\bipom\\devtools\\MicroC\\Lib12 folder.
As minimum action  you have to uncomment  RESET vector (6812RLS.ASM)

*
* DDS MICRO-C 68HC12 Runtime library - Suffix file
*
?heap      EQU      *            Heap memory goes here
* For stand-alone ROM system, uncomment the following
     ORG      $FFFE            Position to reset vector
     FDB      ?begin            Set start address
*00000

If you use Mini-Max/908 board the system can be reset if PTC1 goes low for 2 seconds.

> Found a possible solution.. let me know if it\'s correct
yes, it\'s correct.
It is necessary to empty I2C buffer periodically.
The buffer has only 8-byte depth.

Also, you can reset the I2c Pointer only (CLR=IP).
This way you can re-get all the bytes from buffer again.

> Question :  
> How can I explicitly set some lines as inputs and some > as outputs in port A ?

You can do that using TRISA unit.

#define PORTA_UNIT                        0
#define TRISA_UNIT                        1
#define PORTB_UNIT                        2
#define TRISB_UNIT                        3
#define PORTC_UNIT                        4
#define TRISC_UNIT                        5


For example, you would like to have 3 inputs( PORTA0..2) and 3 outputs (PORTA3..5).
It means you have to write 7 (000111B) to TRISA.
1 defines  input
0 defines output
