Syntax:
HI2CSend data
Command Availability:
Only available for microcontrollers with the hardware I2C or TWI module.
Explanation:
The HI2CSend command will send data
through the I2C connection. If in
master mode, HI2CSend will send the data immediately. If in slave mode,
HI2CSend will wait for the master to request the data before sending.
Note:
This command is also available on microcontrollers with a second hardware I2C port.
HI2C2Send data
Example:
This example code retrieves multiple bytes from an EEPROM memory device.
do
HI2CReStart ;generate a start signal
HI2CSend(eepDev) ;indicate a write
loop While HI2CAckPollState
HI2CSend(eepAddr_H) ;as two bytes
HI2CSend(eepAddr)
HI2CReStart
HI2CSend(eepDev + 1) ;indicate a read
eep_i = 0 ;loop consecutively
do while (eep_i < eepLen) ;these many bytes
eep_j = eep_i + 1 ;arrays begin at 1 not 0
if (eep_i < (eepLen - 1)) then
HI2CReceive(eepArray(eep_j), ACK) ;more data to get
else
HI2CReceive(eepArray(eep_j), NACK ) ;send NACK on last byte
end if
eep_i++ ;get set for next
loop
HI2CStop
Supported in <HI2C.H>
