SERVOCENTER

before i saw this webpage i ordered a SERVOCENTER USB 4.1 CONTROLLER from amazon.com

what is your opinion, have you or someone in this forum used it, test it?

where can i get more info, their website does not give as much information as you do over the axon...

thanks for your help...

Only $4 cheaper than an Axon but with no decent documentation or examples? Can you return it?

Anyway, it uses an ATmega325P. You can just program it like the $50 Robot (with microcontroller upgrade tutorial).

It has a bootloader like the Axon, but no ISP header so you can't use a hardware programmer.

So just write a program using AVR Studio, compile it, and upload the .hex with the bootloader. This should have everything:

thanks, i think i can´t return it, jeje

what is ISP header? hardware programmer?

[Joker94]

A ISP header is 2 rows of pins, either 2rows of 5 or 2 rows of 3, These days the 10 pin programmers are becoming obselete and the 6 pin programmers are taking over. I attached a pic of the ISP pins on the $50 robot board.

And this is a programmer, i linked to Airman00's page on a 6 pin AVR hardware programmer.

hope this helps.

Hi,

what is ISP header? hardware programmer?

ISP (with some controllers called ICSP): In-Circuit Serial Programmer. A programmer connected to the assembled microcontroller board for programming the controller while it's still in the circuit. The "Serial" is vs. a parallel programmer, which needs access to more lines and needs the controller to be out of circuit. A parallel programmer is much faster in programming a controller and if you have to program hundreds or thousands of controllers, this is the way to go, but this seldom means much to an experimenter, who  spend most of the programming time writing code and searching frantically for the bit of code that keeps Nirvana at a distance.

Header: The connector type used is called a header, but the word "connector" is just as valid.

Hardware programmer: The gear you use for programming (aka. burning) the controller (transfering the program from eg. a PC to the controllers program storage space).

much better technical explination soeren.
