Si7051 Temp Sensor
Posted: Fri Dec 15, 2017 11:26 am
Hello
has anyone perhaps used the Si7051 temp sensor from Silabs?
having a hassle trying to get data out of this guy, uses I2C
but i cannot really make sense of their protocol
Also i am not sure what address to use...they say they
have 7 bit base address (0x40)...with 8th bit as W/R
100 0000 base addr
1000 0000 WR address is 0x80 for write
1000 0001 RD address is 0x81 for read
Is this correct assumption for starters?
Then first u need to set config register.....ask it to do temp reading.....collect data
i cant even get past setting the config register....hangs
Thanks
