I'm using the syscall method to acces 2 different, i2c buses. (it works very well). I'm using the fimage 311-v100-vhdl. I'm using the fox as the only master and 4 ads7828 on each bus, as slave. Due to lack of open collector output, I'm using 3 lines for each bus, 1 clock out (OG28 for first bus, OG5 to drive the gate of a fet 2N7000, for data out and IG5 for data input) All works correct at about 100khz rate.
Now I have selected for the second bus OG25 as clock out and OG28 as data out and IG2 as data in. The problem is that I cannot send clock on OG25, also using setbit program as described on acme web site, I cannot toggle low OG25. # setbits -p g -b 25 -s 0 Is it already used for other task in this image ? thanks for your help Andrea
