Hello to all,
I need on to build a thermo-hygrometer with Sensor AM2321 using the I2C bus with a pic 16f876 using mikroBasic. The datasheet is only in Chinese (?) And trying again and again even though I can not receive data from the sensor. Anyone used it?
Thank you all,
Stefano.

In my program I can able to read 3 adc ports simultaneously
but when i read 5 ports simultaneously it does not reads it freezes.in proteous simulation
my code is below............ please help i need it to read 5 ports simultaneously ...

hello,
i want to develop this project with pic18f4550 and MPXV5050GP i facing the problem on programming on i.e. calibrating the sensor so can anyone help me
I used PIN AN0 and AN1 as input signal and LCD pins are connected to D port

Hello,
I am new to Libstock and the MikroC... I started using it for my senior design project ... my project is about Automatic Irrigation Systems where I use the PIC16877A to control the whole process. I am using the DS18B20 Temperature sensor and the SEN0114 Moisture sensor (http://www.dfrobot.com/wiki/index.php/Moisture_Sensor_(SKU:SEN0114))... There is a problem in the moisture sensor.. it is arduino compatible and I dont know what is arduino... I want some one to help me in creating the the libraries as in how to read and write from the DS18B20 ... also if someone can help me in the SEN0114 problem i would be greatful.
Thanks All,
Hamzah Ghanem
