Re: Cleanflight aka Multiwii port to STM32 F10x and F30x

Belive me, a good code is a code that works and is easy to debug and add new features. Ah, actually, there is quite a lot more to "good code" than that. Dominic has the right idea. As for the flame war, there is a lot of history there. Unfortunately the abrasive attitude from a few people...

Re: ESC calibration

Agreed I to would like a coded option to calibrate all ESC's at once. Doing them all one by one is a pain, especially when you have to dismantle most of a copter to get to all the appropriate plugs and what not. This is what I've created to calibrate ESC on my quad: RC3toMotor.rar Feel free to modi...

Re: Add datas to GUI for PID tuning

I think things should be like this: 1- in GUI mark a bit from AUX1 to make the drone in pid setup mode. Example 1: AUX1 LOW - no setup AUX1 MID - Pitch PID setup AUX1 HIGH - Roll PID setup I think that this process should be safer if for the entire process we hold the drone in hand. In this case we ...

Hello everyone, Here is an idea to be implemented: Instead of using 3 position LOW, MID, HIGH for the 5th channel can be this channel divided in let's say 5 positions. (2100 - 1100)/5=200 I think 200 difference between the positions are more than enough for very good detection of the switch mode. Wh...

I could make some Arduino example code that shows how to read data from the Mongoose using SPI. 50Hz is the standard sensor update rate, but it can go as high as 200Hz. -Cory This is great ... i think 200Hz is more than needed for a simple flying drone.

Re: Mongoose 9DOF IMU with BMP085

You could also provide this little board with a preloaded firmware that will do the data acquisition from all the sensors on the board automatically and drops them over i2c all in one transaction so we can use it with arduino boards. (Food for the brains ... )
