I've got the HiCO.SH3 development kit bywhich hosts a Linux Embedded O.S. The microcontroller that's on the board is a SH3-DSP family more precisely a SH7727 by Renesas which has CPU core, DSP core, MMU, USB etc.
The fact that there is an operating system running on top of everything I cannot access Timer, A/D directly. I want to find a way where I can access all the registers without compromising the OS's integrity.
I need to make an aquisition of a signal through the A/D converter at7.2kHz and make some digital elaboration with it.
Can someone address me a link or explain how the whole system works?
