HI2CRestart

Syntax:

    HI2CRestart

Command Availability:

Only available for microcontrollers with the hardware I2C or TWI module.

Explanation:

If the HI2C routines are operating in Master mode, this command will send a start and restart condition in a single command.

Note:

This command is also available on microcontrollers with a second hardware I2C port.

    HI2C2Restart

Example:

    do
        HI2CReStart                           ;generate a start signal
        HI2CSend(eepDev)                      ;inidcate 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
