16F877A and Sensirion SHT21

[revelator]

Maybe if we ask nicely? Please ....or at least point us in the right direction....

Hold Master mode or No Hold Master
mode. In the first case the SCL line is blocked (controlled
by sensor) during measurement process while in the latter
case the SCL line remains open for other communication
while the sensor is processing the measurement.

Can you please share the code how to work with SHT21 ?

Could anyone share the code for reading the sht21 or the si7021 please ?
Thanks

If you don't need the precision of the SHT21, then use any of the DHT11, DHT21, DHT22, AM2302 sensors and the library file here http://www.picbasic.co.uk/forum/showthread.php?t=19975
