Hello
Is Multiwii is optimized for SimonK ESC firmware ?
I mean, for the refresh rate ?
Is there anything to setup in the code to enable these optimizations ?
Thank you for your help.

Works great with simonk. You don't have to so anything.

Re: Multiwii and Simonk
It should work without issues just set
If you are flashing ESC's by yourself you can also use/try ziss_dm's wii-esc (http://code.google.com/p/wii-esc/) and flash them with extended range (0-2000) and in this case you must also set
in MWII
With that you can get very high resolution on Mega2560 based boards and better (than default) on 328p.
With that option (ziss_dm's and probably also SimonK's) you can rise P for roll/pitch to 7 or higher and you will get incredibly stable and smooth flying experience.

Code: Select all
#define MINTHROTTLE 1064 // special ESC (simonk)
If you are flashing ESC's by yourself you can also use/try ziss_dm's wii-esc (http://code.google.com/p/wii-esc/) and flash them with extended range (0-2000) and in this case you must also set
Code: Select all
#define MINCOMMAND 1008 // (**)
#define EXT_MOTOR_RANGE
With that you can get very high resolution on Mega2560 based boards and better (than default) on 328p.

Hi crashlander
How to flash wii-esc to support ext_motor_range ?
when you say "flash them with extended range (0-2000) " you mean edit predifined throttle end points and set ppm working range from 0-2000 or enything else ?
This setting is suitable for tgy.hex (rctimer 30A ESC)
Thanks Nikos

Yes extended range means to set allowed/valid/useful TH range from 0 to 2000 us instead standard RC 1000-2000.
If you use ziss_dm's flash tool (http://code.google.com/p/wii-esc/downlo ... e&can=2&q=) it is as easy as to select that option from pull-down.
Extended range works on all ESC's (AFAIK).
But be sure to check exact version of your ESC (inside shrink-wrap) since most of ESC's have changed over time (from mix of p and n FET to all n or even MCU change from Atmega to SIL) and kept same label on the outside!

Re: Multiwii and Simonk
Hello,
Thank you for your answer.
I understand how the Simonk firmware is better regarding the range we can change but I would like to know if the multiwii firmware use a better refresh rate thant the standart 50Hz update we use for servomotor for eg.
Is the Multiwii firmware is able to refresh the PPM more faster than 50 Hz ?
Thank you again

Re: Multiwii and Simonk
MWII uses 490Hz refresh rate for ESC control.
