When you do a qspistart how do you select which chip you want then?

Anyone know if the 5282 is 5v tolerant on the spi bus? or do we need a level converter?

Here is what i'm thinking, filter caps are missing it's just a quick drawing

oups ls7766do not using the HCTL2022 have ls7766do's in hand

7766 D0-D7 to D24-31 through 74lcxr2245 configured as bi directional

7766 RS0-2 to A32-34 through 74lcxr2245 configured as out only
7766 CS to cs1 through 74lcxr2245
7766 WR to D23 through 74lcxr2245
7766 RD to D22 through 74lcxr2245 ...

having problems finding documentation on interfacing and using the databus, anyone have any info?

Thanks

Yes

use a 7hc02 to qualify the chip select and the read/write signals, use a 'hc244 buffer between the chip and the databus that is selected by the '02 parts

with the 7760 parts you don't need the '244 or the '02 parts, you use the QSPI to talk to the 7760 parts along with two QSPI chip select ...

Speed is an issue looking into using a couple of lcxr2245's and the 7760do, just trying to narrow down the clock source... and am i right on thinking i can use the j1 data bus pins for this?

was looking at that one but we order all our stuff from digikey...

I have to read 2 encoders with my 5282, and was wondering if i could use a hctl-2022, this counter uses an 8 bit interface so i could plug it into the data bus on j1 right?

tried another app that was compiled a long time ago different sdk version and flashing works fine with autoupdate, same board just different application...

Sdk v 2_5_2
