Re: [ts-7000] PEEK/POKE or pointer access

["Don W. Carr" <>]

Also make sure you compile with: -mcpu=arm9

But, peek and poke are just written using memory access. You should declare pointers as volatile to make sure that the compiler does not optimize out a pointer access in a loop.

I have been going through the sample programs and documentation for the TS-7xxx boards
while writing code to access the ADC and GPIO pins of the TS7400. Some of the sample
programs use pointers to access the ports, others use PEEK and POKE routines from
peekpoke.h

It looks like the ADC access is all 32-bit, and the GPIO is all 8-bit. Is there any reason to use
PEEK/POKE, or will pointer access work reliably?
