Re: WMP+NK direct connexion

May be add other pull-up ? http://wbb.multiwii.com/viewtopic.php?f=6&t=178&start=10#p1591 I think i should change my pull-ups resistor value. On my WMP, default pull-up values are 2,2Kohm. From any electronic site, I read that pull-up can be in the range of 1k to 10k ( http://www.i2c-bus.or...

Re: Erratic behavior and freeze

Hello!
Blink LED indicate I2C init problem.

May you can just wire WMP for the beginning!
Could you check with an oscilloscope SDA and SCL signals ?

Re: Android tool to modify PID settings

I have a bluetooth module http://www.sureelectronics.net/goods.php?id=402 . The problem is: It is not possible to change baudrate. It is freezed to 9600baud. Max, you have the simplest and least usable (for our purposes) BT module I have heard of so far. I feel truly sorry for you. Can you please t...

Re: Android tool to modify PID settings

btw, how did you connect the 3.3v device to the arduino? did you use a regulator and a logic level convertor?


I used low drop voltage regulator (ST - LE33A)

Re: Android tool to modify PID settings

Hi Noobee, I have already tested this thing but unfortunately no response from the BT module (for AT command). But I will try to test one more time for sure. Can you confirm that "AT" command is an ASCII command and correspond to 0x41, 0x54 ?? and may be a cariage return ? What is the name...
