Re: Header for data pins on micro USB connector

Not really if you think about it.

Many people run their raspberry pi off the USB port to their PC or laptop (e.g. I do). Why not have data as well. You do notice that you can charge and run your mobile phone off a PC/laptop USB port too? Same here.

Re: Header for data pins on micro USB connector

You are almost correct. The access you get by connecting to the serial port of the GPIO (UART), is the 'debian' linux console. You get all the bootup messages (and the resulting error messages if it occurs during bootup, easy to debug). You also have direct access to the linux console and can use it...

Re: Header for data pins on micro USB connector

W. H. Heydt I agree with most of your points, and that we do not really need a 'header' only raspberry pi, since it is pretty small already (plus it will screw with the 'economy' of scales, having another model of the Rpi). As for why expose the USB input power's data header, again it's so that we c...

Re: Header for data pins on micro USB connector

Could be an approach, however for flexibility let's just keep the 'd+/d-' pins exposed as a header, instead of directly connecting it to UART GPIO. If i wanted the usb cable to carry nonstandard rx,tx UART signal, I could just wire wrap the 'd+/d-' pins to the 'tx,rx' GPIO pins. If i wanted to insta...

Re: Header for data pins on micro USB connector

I think he is wants the possibility of using the microusb power input as a serial monitor. He doesn't require that the microusb be connected to the SoC, we know the SoC only usb out is directed to the ethernet and the 2 USB port. E.g. connecting the raspberry pi to the laptop, currently only supply ...

request: onboard FTDI usb->serial converter

Similar to how the arduino included an FTDI chip for easy interfacing with a computer with a single cable, I would like to include a serial to usb converter chip in the mini-usb power input. How hard would it be to include this in the next revision? You could use the x-series chip to cut down in siz...

Re: Wishes for 2nd gen Raspberry Pi

What I really really really, would like to see in the next gen raspberry pi, is for the microusb power socket to also double as a "usb-to-serial" converter. This would make it really handy to access serial console, by hooking it to the laptop (if you want to use main power still, then you can make a...

Re: Raspberry Pi talking to an FPGA

Fpga on raspberry pi? Sounds really interesting! I wonder if anybody have though of making a FPGA 'shield' for the raspberry pi. If possible, could you do the programming of the shield over the GPIO pins? Also would it be possible to do the 'synthesis' of the bitstream in the RaspberryPi itself from...

Re: Fantasy RPi 2 spec (what's yours?)

Adding to the above. Instead of using embedded FTDI chip for RPi2, maybe we should do it like the 'arudino UNO' and use a atmega chip instead. This means with the right cable, you can turn the microusb 'power input' port, into an advance usb keyboard, mouse, that is directly hooked into a very power...

Re: Fantasy RPi 2 spec (what's yours?)

This is definitely a must for the RPi 2! You know the 'usb power input', and how it does absolutely nothing? Well what if we can add a FTDI "USB to Serial" chip to it, and hook it to the rpi2's serial output. This means you can hook your RPi2 to your laptop and use the serial console on the RPI2. Th...

Re: Fantasy RPi 2 spec (what's yours?)

I saw a few people suggest adding an FPGA to the mix. I think that's also a good idea too. From what I understand an FPGA will be able to act as a pass through for digital signal. It doesn't sound likely to be able to handle analog signals (I like to be proven wrong though). Do you think this would ...

I wonder if any seen this idea in http://www.frambozenbier.org/index.php/raspi-community-news/7471-oninoshiko-on-raspberry-pi-console-case Basically the idea is that we distribute each games as an sd card. The sd card only has 3 files/folders, a minimal linux distro, a game image/folder as well as a...

Re: PC and Gaming Console Hybrid - solution with Operating S

why not DexOS. However I still think distribution of games via SD cards is still best. Again OS images in SDcards is harder to copy and rip off, compared to just data files. The only problem I can imagine is how to maintain network configurations for network games, between multiple supported games. ...

Re: PC and Gaming Console Hybrid - solution with Operating S

Why be so complicated by having a dedicated console OS? One thing that makes a console different from a fully fledge OS, is that it is fast to load, and focus only on one game per card. So in this case, since Rasp pi, loads everything off a SD card. Just distribute every game as a 'sd card'. This co...
