Well I'm not a musician, though certainly exposed
to it for much of my life (ex wife is first chair
french horn, mother was a pianist, grandfather
was an operatic singer) I just never picked it up myself (rebellion maybe?).

However, Midi I understand, its a protocol the
same as anything else. In fact its used in many
non-music applications as well (xmas lights spring to mind).

What do you have in mind?

Hello,

I need to hire a PIC programmer who is also a musician that fully understands MIDI.

Company is in Michigan, but that doesn't mean you would have to re-locate.

Hi,

I use the AD7705 for RTDs.

16 bits ADC and SPI.

You would think that would be a common chip, but I've yet to find one. One option is to change

to K-Thermocouples and use a MAX6675. The other is to use a RTD transmitter (Omega $75

fits in protective head output 4-20ma) then use a PIC or A/D to get what you need. The upside

is quick integration and they come already calibrated (What's your time worth). For a small

batch it's probably the best way to go.

Hi,

I've got an application where an existing RTD interface circuitry needs upgrading, and I'm looking for a custom chip that will handle the current sourcing and amplification necessary. The current circuit is composed of op amps, resistors and caps, and I would think there would be a single chip solution for this, possibly one that might also have a built-in ADC of 12 bits or more, and have an SPI interface.

I know that Christmas is a ways off, but a chip like this would save us a lot of board space. Seeing that RTD interfacing is a very common application, one would think some chips would habdle this.

Thanks all.

Hi,

I've got an application where an existing RTD interface circuitry needs
upgrading, and I'm looking for a custom chip that will handle the current
sourcing and amplification necessary. The current circuit is composed of op
amps, resistors and caps, and I would think there would be a single chip
solution for this, possibly one that might also have a built-in ADC of 12
bits or more, and have an SPI interface.

I know that Christmas is a ways off, but a chip like this would save us a
lot of board space. Seeing that RTD interfacing is a very common
application, one would think some chips would habdle this.

Thanks all.
