VBAT compensation for pid (PD)

When battery voltage is over the nominal value it decrease P and D PID for pitch, roll and yaw to 80-100%. Add to config.h #define VBATCOMP 111 //aku voltage compesation for pid PD pitch roll. 111=11.1V for 3s, 148=14.8V for 4s etc. Remember to setup pid when aku voltage is near nominal value. Add t...

Re: Activating 16-bit Timer for Arduino Mega

Today I have checked 16 bit timer implementation on my quadrocopter and it's working very very nice. I only add options EXT_MOTOR_RESOLUTION and support for extended motor range. config.h #define EXT_MOTOR_RANGE #define EXT_MOTOR_RESOLUTION Output ... #if defined(MEGA) #if (NUMBER_MOTOR > 0) #ifndef...

Re: Alternative ESC firmware (reflashing)

funth1ngs: I changed fusebits and its working great. Thank you very much. Only one question. Mystery 12A ESc like the others Mystery has two source of 5v on PCB. One is for atmega and second is for external device (receiver etc.) We can't power microprocesor for 3pin connector. Is it safe to flash (...

Re: Alternative ESC firmware (reflashing)

I tried flash ESC with all kind of setings (in option section) but problem still remain.
The AVRootloader which I use, is from your link and it seems that UseVerify is set (.equ UseVerify= 1 )

Re: Alternative ESC firmware (reflashing)

I have problem with AVRootloader. I flashed ESC with software form first post on this site http://www.multiwii.com/forum/viewtopic.php?f=13&t=516&start=160 and set fusebits to High-Fuse: 0xCC and Low-Fuse: 0x2E Now i can connect with flash software, write and read EEPROM, erese FLASH. But if...

Re: Alternative ESC firmware (reflashing)

Hi Sorry for my english. Two weeks ago I reprogram my ESC (Mystery 12A blue series) with firmware from this topic. Quadro is now stable like never before. Thanks a lot for this soft But I have big problem. About 50% of crashes (three times) were ending with burned transistor (AO4409). The strange is...
