MultiWii

Although I am now using just 16 MHz but I would like to go down to 8 MHz. Then I could run it at 3.3V.

Hi David,

many thanks! I'll do it myself tomorrow ago. I also think that it was the master - slave has to do.

Fritz greeting

Hello djrm,

can you give me your code please send to us. in the slave and the master in.

I can then compare the times with mine. I think I've got an error somewhere.

thank you

Hello, Unfortunately for me ha not done anything yet. My GPS does not work still. Now I have sometimes looked at the code more closely. What about the i2c address? What do I need to adjust? Because of what is read and write. Do I have any of the motherboard in a different address as set in the gps b...

Hello MicroRaptor yes, the two files I've already replaced two times. I also have just one more time controls. This is correct. I now have time measured with the oscillator at the i2c. The motherboard is made ​​through the i2c data. Here you can see the communication between the sensors and the proc...

Hello again, Now I have the GPS module built up again with an Arduino Pro Mini Board. SCL -> SCL, SDA -> SDA. Both at 5 volts, RX -> TX and TX -> RX. The GPS module is receiving satellite. EOSBandi code on the Arduino and the address 0x20 set point. Otherwise, I've changed nothing in this code. In t...

Ok, if you look at the code closely at times, then you can also see what NMEA protocol is used

NMEA GGA, GSA and RMC

Greetings Fritz

I have asked the manufacturer of the GPS module after a firmware with the preset data, he asked me what I would have set these values​​. Now I know not whether GGA, GSA, VTG. What am I supposed to be set? When I connect the module to change the mistakes of the i2c nothing. The Mag is bouncing around...

Hello,

what needs to be set in the GPS?

115200bps
10Hz

and GGA, GSA, VTG ...??

Greetings Fritz

Aclosed someone has of you as a circuit diagram of the GPS module? I think it does not fit with me.

you have I2C errors ! your I2C link with the I2C GPS is not working. One reason is perhaps your I2C speed. If it's not 400Hz you need to change the speed in the file twi.h to #ifndef TWI_FREQ #define TWI_FREQ 100000L #endif Thank you! With me is in the set twi.h 100,000th I have now changed times. ...

Hi all, sorry for my english, it's not so good. Read and understand it but I can not write with it that way. so I google for help taken. For a few days now I try the GPS with an extra at328 connect via i2c. That does not really work. The MultiWiiConf shows me no Staliten. Add to my window's and my e...
