MCP2200
EXAMPLE 2-16:
2.3.1.17
ReadEEPROM
Function:
int SimpleIOClass::ReadEEPROM (unsigned int uiEEPAddress)
EXAMPLE 2-17:
2.3.1.18
ReadPin
Function:
bool SimpleIOClass::ReadPin (unsigned int pin, unsigned int *returnvalue)
EXAMPLE 2-18:
Summary:
Reads a byte from the EEPROM.
Description:
Reads a byte from the EEPROM at the given address.
Precondition:
At least one call to the InitMCP2200() is required in order to initiate a DLL search for the compatible
devices. VID and PID must be previously set via a call to InitMCP2200(VID, PID).
Parameters:
uiEEPAddress
- the EEPROM address location we need to write to (must be from 0 to 255, inclu-
sively).
Returns:
This function returns any positive value as being the EEPROM’s location value:
E_WRONG_ADDRESS (-3) - in case the given EEPROM address is out of range
E_CANNOT_SEND_DATA (-4) - in case the function cannot send the command to the device
Remarks:
None.
Summary:
Reads the specified pin.
Description:
Reads the specified pin and returns the value in returnvalue. If the pin has been configured as a
digital input, the return value will be either ‘0’ or ‘1’.
Precondition:
Must be previously configured as an input via a ConfigureIO call.
VID and PID must be previously set via a call to InitMCP2200(VID, PID).
Parameters:
pin - the pin number to set (0-7)
returnvalue - the value read on the pin (‘0’ or ‘1’)
Returns:
This function returns True if the transmission is successful and returns False if the transmission fails.
Remarks:
None.
