[Tinyos-help] Port Numbers

[Mohammed Al-Saleh]

thanks Macro,

I know how things work in the high level (through TinyOS components and 
interfaces). The thing I was asking about is the mechanism (at the low 
level) by which the stream of bytes (will make a packet in the higher level) 
will be stored in the I/O space and from there into the SRAM (i.e., 
addresses above the I/O space registers). It seems to me so far (and as Roy 
pointed out) that it happens through the SPI which can directly write bytes 
into a specific data register in the I/O space (may be 0x0F). I am not sure, 
though. Any more help or contribution is very welcome

...Mohammed
