3DOF power simulator

Hi thecure,

You mean like this one? http://www.ebay.com/itm/1-pcs-ATMEL-ATM ... 910wt_1267

Yes, that is one way to get Atmega644. But maybe you can try using Farnell as they have other parts that you can order along.

The "FTDI - UM232R - EVALUATION KIT, USB-UART, TTL, FT232RL" in the link you gave above, is not directly compatible with AMC1.6. You will have to rewire it to use it as it has different pin number assignments.

ok...tks I found everything on ebay ... diplay and chips. The board FT232RL USB to Serial Module USB from america (---the time is sooooo long:D )

then perhaps buy jrks and have them on your doorstep in 3 days.......
Really, give the suppliers a chance...the tronic is a good board , even if some parts take time to get there....

the crystal 22.1184 mhz, it' 16 pf not 18pf.....can fit

[tronicgr]

16pf crystals are usually SMD package (really tiny surface parts).

You need to make sure its a through hole part:

and I got the chip, but I know that is not the right one
and ATMEGA644-20PU-16 MHz 8-bit 64K-FL-2K RAM-EE 2.7 to 5.5 V 40 DIP

if its not right .. this?

Hi Thecure,

The "ATMEGA644-20PU-16 MHz 8-bit 64K-FL-2K RAM-EE 2.7 to 5.5 V 40 DIP" is correct chip.

I don't know why they marked it "16Mhz" since they already put the correct speed right before that: "20PU"

Best Regards,

ok...tks

I mounted the PCB and everything works Does the circuit works with version 2.0 of the x-sim ? ...tks

:D I mounted the PCB and everything works Does the circuit works with version 2.0 of the x-sim ? ...tks

I tronicgr
a little ignorant question:
believe that the motor for the rotation of the base we can omit the reference potentiometer or encoder?

doubt it is because the rotation is free ...
without reference only the data of X-SIM

always sorry for my "perfect" English
