There are quite a few expansion board ideas about see http://elinux.org/RPi_Expansion_Boards all are welcome, especially open designs. Thank you for the link! But as far as i see - no full featured RS232 is there - but i will have a more decent look into it later on :) As stated out, these designs ...

Hi folks, i just want to present my plans for R-Pi. I want to bring up some little stackable expansion boards giving you the chance to communicate via several protocolls (RS232-full, RS485/RS422, etc). I already build some demo boards for RS232 full-featured (with sideband and flow control) and am w...

Hi, I have got to a point now where i can finally compile a module on my pi, but i am getting an error when trying to load it. This is the output when i do a make: make -C /lib/modules/3.1.9+/build M= modules make[1]: Entering directory `/lib/modules/3.1.9+/build' CHK include/linux/version.h CHK in...

We had had more reports like this. ("When I plug in the HUB my 5V in the Raspberry-Pi increases"). In principle the HUB should NOT output power on the slave port. But it seems a lot of HUBs still do so. Even the diode is wrong. Basically a USB slave port should only take power, it should never prov...

So, to get the Pi and my USB HDD to be friends at power off, would the USB connection still work if I sever the power connection but leave data lines intact?w Only kill the +5V - GND should keep connected. But i suggest on the long run it should be fixed in hardware with diode or fet switch. Rgds J...

You mean hotplug support - i think this would be very helpful ... As far as i see HDMI_HPD_P is connected to GPIO46 - so hardware is fine so far. What have to be done is to reprogram graphic driver to watch the INT on this GPIO and than read out EDID data from monitor - in theory it is simple, in re...

Hi Luke,

can you post how you managed to compile a kernel modul? i am at this stage and cannot get further due to errors ...

I wrote my problems down here

Hello folks, i want to build a kernel modul supporting full RS232 using GPIOs for the sideband/flow control signals. Using this HowTo http://tldp.org/LDP/lkmpg/2.6/html/x181.html, i tried to compile the first demo modul out of this howto but i fail - and thats the point where i do appreciate some he...
