Better than the MiKroKopter

This my first post.

 

I want the MikroKopter and if I had the money, I would buy it now.

I think that I can do better and I think MultiPilot 32 is an advanced controller.  I want to build a Hex around it.

 

Jus' needed to put something in this folder.  It was empty.

  • Hi Christofer,

    i think that at the moment the VRBrain with Arducopter32 rev 3.1rc4 with or not OS work fine better of old Mikrokopter projet :)

    • That's nice to hear! Thank you Roberto.

  • Hi Marty,

    so MP32 is an Evolution of MP1.0 http://code.google.com/p/lnmultipilot10/wiki/multiboard

    If you check the functionality of MP 1.0 and Mikrokopter FC 2.0 you can found that they have same processor same shape and same sensor.

    So MP32 is a evolution of MP1.0 the main difference is :

    Micro :

    AVR 644P MP1.0 is only 8 bit 64 kbyte flash and 4 kbyte ram the speed is 16 mhz

    STM32 MP32 is a 32 bit 512 kbyte flash and 64 kbyte ram speed is 72 mhz.

    Sensor:

    MP 1.0 mount a very good sensor 3 ADXL610 as gyro and lys 344 as accelerometer. than a good analog barometer but the main problem was the risolution of analog input. The main problem is the resolution of adc converter only 10 bit.

    MP 32 don't have integrated sensor but can connect any kind of sensor that you want to use , analog or digital , entry level or professional , the analog input is a 12 bit so can have more resolution of MP1.0 the bus available is the same of MP10 I2C,SPI , but add a second SPI and a second I2C that could use the CAN bus ,too

    Is possible to use a DMA access to the bus so the update of sensor could be a lot better of MP1.0. A big problem that i had with MP1.0 was that all the digital sensor available use 3.3 volt technology , but the native voltage for avr 8 bit micro was 5 volt , so need a electronic circuit to adapt new sensor as digital magnetometer or digital barometer. MP32 is native at 3.3 volt so you don't need any kind of adapter circuit , but you can connect any kind of 5 volt of sensor to MP32 because the MP32 input is 5volt tollerant only some for example the analog input isn't

    INPUT - OUTPUT :

    On MP1.0 is only available PPM_SUM input using one interrupt timer 16 bit and an i2c output to control the Brushless controller than there're some PWM output generated by a very bad PPM output with low resolution and with a lot of glitch , low level rate :( Is not possible to use it to control standard ESC PWM directly.

    On MP32 is available the same configuration of MP10 plus a lot of PPM input and a lot of high resolution PWM output at high resolution 16 bit antil 32000 poin of resolution inside the 1000-2000 micro second time window. Instead of a standard 8 bit 127 point of resolution fo 8 bit pwm generated by MP1.0 .

    So the main difference is that on MP32 instead that of Mikrokopter FC 2.0 you can use any kind of accessories , without any kind of patch. All radio receiver , not only PPM_SUM and a lot of ESC controller not only i2c.

    So you can use also i2c controller and the advantages is that is not share with the sensor and so you don't have bus conflict problem. The sensor use a bus and the motor another bus.

    I think that MP32 is a good improvment in hardware , now we're working hard on firmware to have a better of Mikrokopter ,too The last revision of Arducopter NG 32 and the future revision of Arducopter Mega 32 will be available all the function supported by Mikrokopter with a lot of more powerfull available and use of most advanced sensor available on the market MPU6000 x example 1 chip solution with integrated gyro , acc and where you can directly connect magnetometer.

    That's only a small introduction on difference.

    Best

    Roberto

    • I did not understand all the too technical stuff you mentioned. To simplify, is Arducopter 3.1 running on VR Brain 32 better than Mikrokopter?

    • How can i configure 6Y frame configuration?

      Is it on the parameter list?

    • I only hope you keep to English so I can help you with this project.

      I am language impaired when it comes to Italian :)
