I am a software engineering trying to learn to use AVR microcontrollers. Sorry I do not know any electrical engineers to example the circuit side of things to me.
I have a Atmega16 and I wish to measure temperature using the DS1621 via 2-wire protocol.
I have my circuit set-up in my STk500, however I never get any temperature readings from the DS1621 in program. I am supply the 5 V off the VTG pin on PortB.
Do I need to pull up resistors to 5V on SDA and SCL?
(I have seen examples with PIC that have these pullup resistors, typically 4k7?)
Is it possible to debug using AVR studio with GCC on the STK500?
Are there any instructions available to explain how to do this.
