I2c driver code example

Hi,

it seems the SHT75 is using a non-standard 2 wire protocol. You can try to google or search in this forum whether someone has already worked on it before.

Hi,

    Thanks for information ,I have already got my problem solved .

It makes no sense asking for an I2C driver code example when the sensor cannot be addressed by I2C protocol.

Being able to connect to an I2C bus only means that the sensor has a two-wire open-collector interface. However, you cannot access the sensor whiel other I2C peers are on the bus and v.v.

 Just start from scratch. Pick two GPIO lines with external pull-ups. Set PxOUT to 0 and switch PxDIR between output (low) and input (high). And then do with the lines what the sensor requires.
A software implementation of I2C is done exactly the same way. But of course uses different sequences.
