Hi Guys,
This must be my lucky week. A friend gave me a nice and small power
supply circuit, it was originally an eval board for a laptop power supply.
It is tiny, works great, and runs nice and cool. It's a lot less bulkier than
the parvus pc/104 (power distribution I) module that I was using. The
other cool thing is that I got my hands on a PCM-3200 sound board.
With any luck I will soon be doing audio conferencing, speech systhesis
and speech recognition on the wearable. The problem I have here
though is IO address and IRQ conflicts, expecially since I am running
two ethernet cards (AMD 10-Base-T and Rangelan2 wireless) plus
four serial ports that want their own unique IRQs. Questions:
1) Does anyone know if I can just grab the parallel port IRQ (7), or do
I need to somehow disable the printer function(s)? I am running
redhat linux 6.1.
2) Can anyone recommend any good audio conferencing software?
I have Speak Freely for unix installed on my laptop and I can
receive audio but I'm having problems with the microphone.
3) Any recommendations for other useful audio applications for the
wearable experience?
A while back I was asking about how to switch between serial ports
to poll devices such as GPS, accelerometers, etc. I am making some
good progress there also. A friend is helping me design a switcher
based on BasicX BX24 microcontrollers. We have removed my GPS
receiver from the RS232 port on the mighty mite carrier board and
interfaced it to the BX24 via two TTL serial pins on the BX24, and
have it routing through the BX24 to a serial port on the mighty mite.
We are going to add a couple of Max232 chips and have the BX24
switch between ports. I am going to write a new Java API to make
access to these ports basically the same as regular ports, plus a
specialized class that will automatically poll among ports.
We are then going to add a second BX24 to interface to relays for
switching peripherals on/off and drive LEDs, TTL interfacing to
some ADXL accelerometers, and to tap onto my ricochet modem.
I want to switch the ricochet on/off with software, plus take the
output of the ricochet "status LEDs" and trap those signals in
software (feed them into digital inputs). This way my software will
know if my modem has found a transceiver, how good the net
connection is, and when I have lost the connection. This will
lead to intelligent roaming software that can automatically do
things like switch to CDPD connection. These BX24s are quite
interesting little beasties (http://www.basicx.com).
