hi,
I use the LPC11C24 i2c and AT24C16 communication,I am using NXP official example.as follew:
/* Master tx only */
int Chip_I2C_MasterSend(I2C_ID_T id, uint8_t slaveAddr, const uint8_t *buff, uint8_t len)
{
I2C_XFER_T xfer = {0};
xfer.slaveAddr = slaveAddr;
xfer.txBuff = buff;
xfer.txSz = len;
while (Chip_I2C_MasterTransfer(id, &xfer) == I2C_STATUS_ARBLOST) {}
return len - xfer.txSz;
}
/* Sequential master read */
int Chip_I2C_MasterRead(I2C_ID_T id, uint8_t slaveAddr, uint8_t *buff, int len)
{
I2C_XFER_T xfer = {0};
xfer.slaveAddr = slaveAddr;
xfer.rxBuff = buff;
xfer.rxSz = len;
while (Chip_I2C_MasterTransfer(id, &xfer) == I2C_STATUS_ARBLOST) {}
return len - xfer.rxSz;
}
- This wrapper function is not provided from the slave device register address,Only the slave hardware address is provided（uint8_t slaveAddr,）,Causing read and write errors. How can I do the right to read and write？I do not know how to control the register address.Who can give me some advice？
Who can give me some examples of reading and writing？
