I am working with 21065L with ezlite kit. we have DSP++ 2.0 full
version and DSP++ 3.5 limited version.
I am strugling to read ADC data on both SPORT & Parallel ports via
EMAFE port of ezlite kit.
I am using AD7676 and following EE247 of ADI.
I am able to write in to device i.e start of convertion & an LED
conneted at Busy is litting both in single step & continuous mode.
BUT THE DATA READING IS NOT CORRECT AS PER MY INPUT TO ADC(DC VOLTAGE).
Pl. help me in this regard with suitable code.

If your input is capacitively coupled, you won't be able to read a DC
voltage.

Hi,
I'm trying to generate a software reset, using "raise 1" instruction but
it seems not working.
My need is to be able to reset my program when i want. So i call a
function which will reset BF533 and when my application restart, by
reading SWRST register i'm able to see if reset is due to watchdog or
reset invoke by program.
I try the following instructions : (C language)
Asm("raise 1;"); Not working, application doesnt restart
----
*pSWRST = 0x7;
ssync();
*pSWRST = 0x0;
ssync();
asm("raise 1;"); Not working, application doesnt restart
---------------
Could you help me and give me idea or code to reset BF533 and read SWRST
register to identify reset reasons?
Thanks in advance
