Hi ,
I am using PCF8574T I/O Expander along with Accelerometer and when i am trying to writing to the PCF8574 my I2C code hanging and also I am little bit confused with PCF8574 Input and output configuration, so please any one suggest or send me sample code for PCF8574 with I2C.
Thanks.
Hi Vanaja,
In order to better analyze where the problem might be, could you please send me a complete schematic? And if you have a logic analyzer, it would be also fine to see what is going on the I2C bus.
Best regards,
Tomas
