Hi
I am using my flow kit 2 to analyse some SPI signals using megga 2560
I have set the slowest clock speed i can currently select on the megga 2560 ie /64
But currently do miss a few clock pulses even if i set the clock speed to the FOSC /64 on the megga
Is there any way i can reduce the SPI clock speed still further initially for my tests to allow me to continue utilise the flow kit 2
Note i can monitor the actual clock pulses and they are fine using an external logic analyser ie non missed
Best Regards
David

Re: spi flowkit
Hi David,
Options might be to move to a software SPI channel or to change the crystal on the arduino.
I personally use something like this and for the price it does very well.

Re: spi flowkit
Hi Ben
Don’t want to change crystal as potential problems likely with booth loader and other things
May try an 8 meg 3.3v arduino
But really wanted a small mod to the software SPI clock freq
Already use the analyser you mention and that’s fine for just monitoring the lines
