1  Using Arduino / Networking, Protocols, and Devices / Re: Settimino : Ethernet library to communicate with S7 Siemens PLC. on: December 03, 2013, 12:45:25 pm
Hi Davide. Felititations for this magnific job.

I'm try the example RunStopDemo, and I can' connect to my Logo! OBA7. The logo IP is 192.168.4.50,
and the ethernet shield+UNO  is 192.168.4.11.
Could you say me if the modifications are correct?

Reagards,

The 2W resistors are for sensing motor current.

Hi MarkT, reading the data sheet I think there is no problem with this two voltages. When I check the first prototype I see it! Fried Arduino!

Now is update the second version. Soon we start the design of the PCB.

Thanks Erdin!

Hi Erdin. Thanks!, I will change this items and re-upload it!

Hi All. Here is the first second schematic of a new project. A Brushless DC motor shield.

It use a Allegro A4960 IC controller and a IPD090N03LF n-channel mosfet of Infineon (30V-30A).

We accept contributions or comments.

I try use the sensored motor without sensor feedback.
I think that is very rare than there isn't a more modern version of MC33035. I search a lot and I can't
found it.

Hi. I see in this site:
 
http://www.circuitsathome.com/diy-2/advanced-brushless-dc-motor-controller/comment-page-1#comment-18643

a good solution. Oleg use the A4960 IC from Allegro. I think this is my choice. I will tried It.

Regards,
Jaume

Hi MarkT. I read some papers of Atmel like AVR443 and AVR444, and problably is my 2nd option. my first optin for simplicity is MC33033, but I can't understand
if I can controller it by Arduino, specialy the speed input. Now I seach info about FAN7388.
The ratings of my motor are about 12-15V and 10-15A.

Thanks.

Hi everybody. I want to make a shield for control a brushless DC motor. I don't like a ESC rc controller.
Searching IC's for do It, I found the MC33033. Somebody use it before? Is there another better IC?
Thanks for your help.

Estoy encantado con este tutorial que se me había escapado. Gracias SrDonGato.
Cuando me llegue el Raspberry Pi probaré si funciona en el.

Hola a todos. Como estais hablando de Flux, yo hace tiempo que me lo "fabrico" siguiendo los consejos de pedrolo.com http://www.pedrolo.com/index.php/fabricacion-placas-pcb/98-barniz-casero-para-placas-pcb.

Para ello mezclo alcohol isopropílico (Alcohol de limpieza Eroski, 2,5€ aprox. por 1,5 litros), con Colofonia (tambien llamada perrubia, pez rubia, "pega grega"). En Barcelona la compro en Quimics Dalmau http://www.quimicsdalmau.net/v2/productes.asp?abc=C&cat=0&busca=&orden=abc&valor=C&pag=8&masmenos=&idprod=&num=, por 8€ aprox el kilo.

Disuelvo en 100 ml de alcohol unos 25 gr de colofonia, hasta la saturación.

A mi me va de muerte por un coste mínimo!!

Ya me direis si alguno también la usais.

Gracias JRodrigo. Entonces, ¿como lo programas ahora?.

Hola a todos. Estoy "estudiando" el littleduino, felicidades JRodrigo! y tengo 2 dudas.

1. En el circuito de reset, aparece un DAR (serigrafiado auto-reset), que no se lo que es (que mala es la ignorancia).
2. En el adaptador usb-uart de ebay, me parece que el orden del conector no coincide con el de la placa, quizás no lo veo bien
o ¿lo conectas con cablecillos?

Saludos y felicidades por tu placa!!

Muchas gracias Dukatus!!

Mañana lo pruebo!
