Re: [Paparazzi-devel] ADC channel for Gyro

[Michel GORRAZ]

Hi,

The easiest way to connect a ADXRS300 on a Tiny v2 (or a Twog) is to use ADC5 on the "ADC2" connector
- GND on GND (pin #1)
- +5V on +5v (pin #2)
- Rateout on ADC5 (pin #5) => resistor bridge for 5v sensor is included for this ADC on the Tiny V2

And... that all !

Don't worry, ADC1 is probably alive :)

Hello,

Thank you Michel. GTK. Can I ask a question related...

My Gyro is 5v (ADXRS300) with ST1, ST2, TEMP, 2.5V, RATE, GND, 5V..

Can someone please give the pins to connect to the Tiny on ADC2? 

5v is easy -> +5v on Tiny

GND -> GND on Tiny

....

Without any instructions on the Wiki about the connector and going by the funjet1.xml airframe file given I had it connected to ADC1 

GRYO ---- TINY

GND -> GND

RATE->ADC3

5V->+5v 

I hope I didn't damage ADC1 on the Tiny

Thank you,

-David

So, if I were to connect my 5v Gyro into

Hi,
For sure, you can use this ADC with a Gyro (or  other analog sensor) but this is a 3.3v max input level, so if your gyro  is a 5v, don't forget the resistor bridge...or use  ADC5 or ADC6 : these inputs have their own on-board resistor bridge.

Hi guys


 I was wondering, on the "USB" port on TinyV2 has a ADC_7, could I use this
chaneel for connecting roll gyro?





Thanks
