Hola Sergio, Sí. El programa se carga desde el Pi a la Arduino. Mira mini_driver.py Si tienes fotos para subir, por favor, publicarlo en nuestros foros. El mini controlador utiliza un Atmega8. Esto tiene los mismos pines como un Arduino estándar, pero menos memoria. Saludos Alan

Hola Alan, desde ya muchas gracias por contestar, la verdad no estaba seguro si iba a tener respuesta al ser de otro idioma! El programa lo carga la raspberry pi al arduino verdad? Si lo conecto vía UART lo carga igual? Me gustaría saber también si hay algún citio para que suba fotos de mi chasis del robot para que lo veas, lo hice a mano de cosas que tenía en casa, por supuesto agregué suspensión que compré acá! Otra cosa, los pines son parecidos al arduino? Quiero saber esto Para agregar futuros sensores!! saludos, y gracias de nuevo!

Estimado Sergio,

Estoy usando el traductor de Google. Así que lo siento si esto es difícil de entender.

Ahora puede ordenar la Mini Driver para Argentina en nuestro sitio web. Como alternativa, si se puede compilar el código para un Arduino, debe sólo tiene que conectar un controlador de motor a los pines 7, 8, 9 y 10.

Buenos suerte.

Saludos

Alan

Hola, soy de Argentina – Buenos Aires, quería que me ayuden a modificar el código de la dagu mini driver boar, para remplasarlo por un arduino mini ligh o un arduino uno, porque es imposible conseguir dagu mini driver boar en buenos aires, y no estoy muy familiarizado con arduino y su entorno, si me podrían dar una mano con esto se los agradecería mucho!!

Desde ya muchas Gracias!!
Saludos,
Sergio Sanchez.

Hi Marios,

As long as you have the EW-7811Un, then you should just be able to follow the Adafruit tutorial, and use their version of hostapd. Our version just aims to cope with different WiFi adapters.

Hope that helps.

Regards

Alan

Hi Alan,
I couldn’t do what you suggested as when I connected the pi to the Ethernet, it wouldn’t come up in the connected devices list in the router’s configuration. But, I took a different route and followed the instructions to build the image. This solved a lot of the problems I had before but something must have gone wrong when configuring the pi as an access point. I do get the Pi network to show up on my computer but when I connect to it the connection is “Limited” and cannot connect to the robot’s web interface. I’ll try again but could you clarify the bit about installing your hostapd? I followed the adafruit tutorial but I wasn’t sure at what point in their steps I should have switched to your instructions (I did at the point that said “Configure Access Point”). Will it work if I followed the adafruit tutorial till the end (and install their hostapd) and then follow your instructions to install yours?
Thanks,
marios

Alan, thanks very much. I’ll be out of town for a few days but when I’m back I will try what you suggest. You will at least get a few days without me bothering you

Hi Marios, To connect via ssh, plug your Pi into your router with an ethernet cable. To find out its IP address, probably the easiest thing to do is to log into your router using its web interface, and look in its 'connected devices' screen. Alternatively you can use a tool called nmap to scan for the IP address. Once you have the IP address you can use the ssh command on Linux or another Pi to connect ssh pi@IP_ADDRESS password is the default 'raspberry'. If you're on Windows then there's a good ssh program called PuTTY. Don't worry about setting anything up on the Pi, Raspbian has an SSH server running by default. Hopefully this should get you in to have a look around, there are lots of tutorials online about using ssh with the Pi that can give more details. When you next get command line access to a Pi that's got your wireless keyboard and mouse working on it, can you run lsusb and send me the output? If we can work out what needs to be installed to get them to work then I can add it to the next SD card image. Although, having said that, our card is derived from Raspbian and so should in theory have everything they have. It could be that something has been added since we last produced an SD card image (September 2014). Regards Alan

Hi Alan,
The thing is that the keyboard and mouse don’t work when I boot up from your image (they work when I boot up from a normal raspbian image) so I don’t see how I can type any commands! You suggested using ssh but how do I get the ip of the pi without interacting with it? Also, don’t I need to setup ssh on the pi first?
Thanks,
marios
