    i am waiting for ur codes for 16 channels of 14-bit BAM, at 610Hz.

    where are them?

    thank u.
    done and working already... for now my code gives 16 bit (E)BAM at 610hz (actually 14bit at 610 hz (1 Tcy discretisation) + 2 bits at 610/2 and 610/4 Hz and channel values are updated at 610/4Hz) my code gives real 610hz refresh rate because i don't use MIBAM, which would steal additional frame giving in result twice lower framerate (for visual perception). for now 16 channel code is working (with same 28-pin PIC18xxxx PCB, i've posted it's photo before), more channels may be easily added if needed (it's possible to make up to 64 channels with external latches upto my calculations, more with internal latches). Actually my algo has some more improvements compared to MIBAM. but i'm slightly drunk for now to describe it)))...
    Sorry guyz, i got no access to internet from home, checking mail very rarely. have no normal job for long time to pay for all stuff i need... Stupid country, stupid government, stupid myself)
    best regardzzz

    hi,i want to watch ur codes.

    thanks.

    i advise u read some works of liening's(Влади́мир Ильи́ч Ле́нин). u will find the hope.
