Ask SILICON CHIP
. . . continued from page 102
honestly, I’m looking for something a
little more sophisticated. Is there a Dev
environment for the PIC that uses, for
example, C? Would you recommend
one that wasn’t BASIC? (T. B. Belconnen, ACT).
• We asked the designer, Geoff Graham, to reply: If you are looking for a
C programming environment for the
PIC, you cannot beat the Microchip
siliconchip.com.au
MPLAB X Integrated Development
Environment and their XC series of
compilers. They are full-functioned
and there are free versions available.
However, be warned. Programming
in the C language can be complex and
difficult – that is why we developed
MMBasic which is much easier to use.
Reducing the gain of
the headphone amplifier
Is there a way to make the 2005
Studio Series Headphone Amplifier
have zero gain? I love running it with
the SILICON CHIP valve preamp however there is simply too much gain
and volume.
Still on the subject of valves, is there
any chance a valve headphone amplifier will be published? As much as
I’d like to try the Currawong I simply
can’t afford the kit cost even though
it’s cheap for a valve amplifier; $700
is simply too much for me (R. K., via
email).
