Re: DSLinux and DSerial Edge

Just a quick update: I can now send and receive data from my PC via RS232 to my DS. :-) I've found that I have had to introduce small delays into the code to make it function correctly. What's left is to glue that into the kernel serial/tty layer, which is such a headmess even the Maintainer doesn't...

Suitable RS232 level convertor for DSerial EDGE

I'm making good progress with my DSLinux driver and I've got to the point where I need to see if anythings working. Unfortunately I have an EDGE, which doesn't have the required line drivers on it. I was looking at the MAX3232CPE+, is this likely to do what I want? http://www.datasheetcatalog.org/da...

Re: how do i upload the firmware?

What file am I supposed to run on my linker to install the firmware on the Dserial?
There's an NDS in /dserial-edge-1.3/nds/dserial-example/ that has the firmware embedded in it, run it and you can use that to upload the firmware.

DSLinux and DSerial Edge

Right, I've made a bit of progress, so I'd thought I'd start a mini blog here. Basically I've done a quick and dirty port of the DSerial lib to DSLinux, which involved changing a few types in the source. I've also had to change the irq handler from libnds to linux kernel. Everything else seemed to c...

C8051F34x as USB host?

In response to a question on the DSLinux forums, would it be possible to modify the MCU to act as a USB host? I understand that a seperate psu would be needed for the +5v but apart from that is there a reason why it couldn't be done, either with a C8051F34x or similar controller.

Re: DSerial EDGE and Slot-2 RAM possible?

Cool, I was checking as I have been warping the inside of my head trying to figure out how to write a device driver for DSLinux and wasn't sure it if was possible. So far I've figured out the following: The SPI layer didn't get implemented into the Linux kernel until a couple of versions later than ...

DSerial EDGE and Slot-2 RAM possible?

Just a quick one, is it possible to use the DSerial at the same time as using RAM in slot-2? I'm half thinking there's a hardware limitation.
