Hi all,

I would like to use ioio-otg to sample some audio signal for an android 
phone. And the default A/D sampling rate 1kHZ is too low for me, I'd like 
to have a sample rate around 10khz.
after read the relevant discussion in this group, it seems I just need to 
simply change a "PR3" settings and build my own firmware. 

So I download a maple ide(now its v2.15) , and then XC16 complier. It seems 
C30 complier is not avaliable for downloading.  after choose the complier 
in ide. I can successfully built
the project and got a hex file as 
dist/ioio0021/production/app_layer_v1.production.hex
then I compiled the /tools/hex2ioio/hex2ioio.c and use it to transfer the 
above hex file to a .ioio file.  But then i am confused about how to use 
the ioio-bundle tools to get a ioioapp file. it required a multiple file 
input but I only have one hex file. 

I am using windows7, 32 bit version. Does I need a cygwin installed to 
build the firmware in cmd line? if so, is there any guild-line to do this? 
I am not familiar with linux environment, so quite worry about it. 

Any suggestions? Thanks in advance!
