Tronic's AMC motor motion-controller with pwm/servo output

Hi Rene,

Unfortunately they are not cheap... They said the can order them. For one piece they ask 35 euro, for six pieces 25 euro and as much pieces you order the prize is falling.

I guess we have to arrange another order the get them from farnell.de ... :-(

Regards, Thanos

Hi Rene,

Thanks for the offer, but I decided to just use a Attiny2313 (that costs 1.5euro) to do the same job!!!

Already builded the code for it in C and it has the exact same operation and resolution of 32bit!! Now building its layout...

I've tested my pcb and my Power Led is dead.

After investigating my board I noticed I soldered the leds the wrong way. After testing the leds, they are still working, I soldered them in the correct way but unfortunately the power led is still dead.

Any suggestions............

I'm so sad about this

Have you checked your pcb while holding it against a strong light source? That way shortcuts can be seen best. Most time it it just a shortcut between the lines or soldering spots.

Thanx Ego,

I will check it. I hope that's the problem.

RoVoR

Yeeeehhhhhoooooooo

My pcb is working. Thanx To Ego. I double and triple and checked it again and again and checked it again and then i saw my lines were etched to much in some places.

Now i will try to program it

I'm so happy to see that power led burning

Re: Tronic's PWM/servo control Interface with encoder/pot input

Hi,

I wanted to mention something about the overclocking I did on the Atmega8535...

Atmel says that the ATMega8535 can be clocked with crystals up to 16Mhz safely. But I could not find then crystals to cooperate fine with RS232 serial operation near that value. The next best value to use is 18.4320MHz or 22,1184MHz. At the time I was developing it I choose to use the even bigger (but easier to find) 24MHz crystal.

I made a little research around the Internet and found little projects that did so big overclocking up to 24Mhz! And I found out that a new batch of ATMega8535 that I purchased sometimes failed to be programmed with ponyprog in 24Mhz. The solution to this is to put a lower value crystal for the programming (for example a 10Mhz crystal) and then place the final 24Mhz crystal.

I'm considering the possibility to compile some firmwares with lower crystal value of 18.4320MHz or 22,1184MHz in case some batches of the ATMega8535 cannot work properly on the extraordinary value of 24Mhz.

Re: Tronic's PWM/servo control Interface with encoder/pot input

Hi,

I found some time during weekend to attach the AVR motion controller on the joyrider using the RNVN2 motor controller:



But I noticed some strange behavior on the wiper motors, that I explain in Bug-Tracker:

Re: Tronic's PWM/servo control Interface with encoder/pot input

Hi,

I received my new graphics LCD (128x64) with touchscreen and backlight! See how large it is:



It can be great add on for the simulator as I could implement a graphical interface to control all the parameters of my AVR motion controller while playing! And since it has touchscreen no extra buttons needed! The way I see it I could use a second atmega that drives the GUI and reads the touchscreen, connected to the main avr motion controller with I2C...

I could even use it to display other stuff like Gear number, Speed, or RPM maybe ;-)

Any ideas?

Regards, Thanos

Re: Tronic's PWM/servo control Interface with encoder/pot input

Would be cool to interface it with the profiler, in order to be possible to display DIY gauges.
But imho virtual gauges have a low priority currently

Your screen looks way more square than 128x64 !??

regards
Christian

Re: Tronic's PWM/servo control Interface with encoder/pot input

Yes, but If I fix it, that way, that retrieves the gauge data from AVR motion controller, it will be much faster! With profiler2 this would be piece of cake! :schreiben:

Yes, its more quare than others that I've seen around...! Have a look on it, in operation:

Re: Tronic's PWM/servo control Interface with encoder/pot input

Thanks Tronic for all you do.

I'm from the states and am ready to build your interface. I have a parts list from mouser.com and hopes its all their and correct. If any one else from the US has found a better source please, let me know. Sorry I couldn't figure out how to do an attatchment.

Re: Tronic's PWM/servo control Interface with encoder/pot input

Hi Jackel,

Thanks for the part list. Would be great if you could make an excel sheet out of it? Quantity/Part/Supplier/Order#

At the bottom of the posting form there are two tabs. An option tab, and besides an uploading tab. After uploading you can place the curser where you want the attachement to be placed in the text and press place in post. Thats all

regards
Christian

Re: Tronic's PWM/servo control Interface with encoder/pot input

Hi Jackel,

Thanks for the list, I will put it on a excel file later to be able to read it better.

Regards, Thanos

Re: Tronic's PWM/servo control Interface with encoder/pot input

I will do that I love spread sheets

Re: Tronic's PWM/servo control Interface with encoder/pot input

Here is that list

partslist.xls

Please add to it. Its better to have one big order that have to wait for small ones

Re: Tronic's PWM/servo control Interface with encoder/pot input

Hi,

I wanted to mention something important about the wiring between RNVN2 and my AVR motion controller.

From the version 1.5 , I changed the pin outs of the molex headers by swaping the pins 7 and 8 to be easy to attach an IDC connector on the RNVN2 side using a flat ribbon cable.





Here is the pin definitions from the RNVN2 manual:

CTRL (10PIN socket IDC)

Pin 1 engine 1 IN 1
Pin 2 engine 1 IN 2
Pin 3 engine 2 IN 1
Pin 4 engine 2 IN 2
Pin 5 return signal of 0 to 2,5V Current measurement for engine 1
Pin 6 Enable Motor1 (PWM)
*Pin 7 return signal of 0 to 2,5V Current measurement for engine 2
*Pin 8 Enable Motor2 (PWM)
Pin 9 GND
Pin 10 logic voltage 5V


JP1 (10PIN socket SIP stripe)

Pin1 motor1 IN1
Pin2 motor1 IN2
Pin3 motor2 IN1
Pin4 motor2 IN2
pin 5 Return signal of 0 to 2,5V current measurement for engine 1
pin 6 engine 1 Enable (PWM)
*pin 7 engine 2 Enable (PWM)
*pin 8 return signal of 0 to 2,5V current measurement for engine 2
pin 9 GND
pin 10 logic voltage 5V

I marked with * the swapped pins for each connector on the RNVN2!

So be careful to swap the correct pins if you are going to connect it using the JP1 connector on the RNVN2 or else you will get no motion on the second motor!

Regards, Thanos

Re: Tronic's PWM/servo control Interface with encoder/pot input

If I had known this before. I've soldered each wire manually to a male molex connector



But I will solder your h-bridge anyway, as the RNVN2 does not seem to be good at all.

Christian

Re: Tronic's PWM/servo control Interface with encoder/pot input

Which purpose have those DIP switches and which position should they have by default?
