Hello All,
I am inexperienced with I2C programming, and have a rather urgent need to get a DHT22 sensor sending data to
virtually any 8 Bit PIC. I am using the PIC 16F1789, but I can work out the differences between controllers, I just need a tested simple routine to gather the sensor data and later display it to a 4X20 LCD.
I am an Electrical Engineer, and am aware of the need for pull-up resistors of about 4.7K to Vcc on both SDA & SCL lines.
I am surprised at the lack of code samples for such a popular type processor as the PIC family, I have found so far.
I have access to both MikroElektronika Basic and FlowCode 7 compiler systems/ ICD's. My Hardware Platform is the MikroElektronika EasyPic V7. Despite looking for some time, I just have not found any examples for coding this sensor using I2C with enough information to get me started. HELP!
I don't have the option or desire of going 1 wire buss.
If anyone can help with this, I would be very appreciative.
Thank you in advance,
-Lisa
