Felix: Yeah it is bidirection; only for one signal though; the data pin. But this doesn't pose a problem though =)

You have got to love the brians in these forums =) Thanks guys.

Hey Felix: I am using the following sensor: ADSX030A2 which requires 5V VDD datasheet available here: http://www.honeywell-sensor.com.cn/prodinfo/sensym_signal_pressure/datasheet/ASDX.pdf For the micro I am using ATMEGA16 not the ATMEGA16L which can go all the way down to 2.5V I think. The...

Hey Felix: The Micro I am using is the ATMEGA16: http://www.atmel.com/dyn/products/product_card.asp?family_id=607&family_name=AVR+8%2DBit+RISC+&part_id=2010 I see that the Vih = 0.6 * VCC so about 5.5 * 0.6 = 3.3V Which is a bit low; but then again my output from the wireless chip is only...

Hey All, I just bought this inverter during lunch and it says that Vmin High is 2V and I can easily output that from my wireless chip since the vdd on that is 3.3V. What is the problem with using diodes? I was thinking of using a voltage divider BUT this will cause power loss. Here is the...

Hey Gunnar, Thx for the link, I've looked it over. I think I will go and pick up some of those chips mentioned in the article. In the mean time I went to my local electronics shop and picked up Inverters and Diodes. Upscale: 3V to 5V. I was thinking of puting the 3V logical high through...

Hey Gunnar, I just needed the right direction; I will do some searching! Thanks a lot for your timely response. Regards, Garmond

Hi all, First post! This place seems pretty friendly and full of helpful resources; I hope I can contribute the same amount that I gain from this site =) Any how here is my question: I have a system with three main components: 1. microcontroller with VDD @ 5V 2. a pressure sensor with VDD @...
