i am working on a similar project to you guys. The program checks a real
time buffer periodically, every second, for serial input data. rt_com
functions read the data in real time and store it to a real time buffer
which is big enough to accomodate a few packets in the occasion that the
buffer is
It will only run on an eval board we have, right. Indy doesn't work yet.
The hooks for each MIPS arch will be different since each Linux/MIPS
machine has a different irq.c. I've updated one port to work with the
modern irq_desc_t structure (just like PPC). I think it's possible to
combine all t

Hello,
I'm trying to develop a real-time data acquisition system in which data will
be read through the serial port. I want to use interrupts to accomplish
this. I have a 16 byte fifo buffer. My question is, how do I ensure that
the interrupt trigger level is set to 14 bytes?
Thanks,
Bill

Hi,
I'm using kernel 2.0.36 and RTLv0.9J.
I am completeing a project in which I have some embedded computers utilizing
the old style shared memory (max. 4 MBytes). I need to increase the buffer
in which I store the real-time A/D values so that I can insure I don't lose
any data.
