Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi Folks,
Anyone here built the Silicon Chip 6GHz Frequency Counter or know of a web site/forum (other than Silicon Chip itself) where any issues etc. were discussed?

Hi Doug

Just wondering if have had any luck with getting any other info on the counter?

I haven't the need for one myself so I can't really help.

No luck so far Brian - I have the E100 all done and working (have built a couple previously so, easy as) and have most of the frequency counter components done - just waiting for a couple of hard to get bits.

The part I would be interested in is anyone going through the software. Not that I am a programmer but the structure of the program (IMHO) is a real mess with negligible comments so it is a nightmare to try and understand. They use a complex CFunction to work directly with the Timers on the PIC32MX470 but have also stuffed a lot of other functions into it (that could have easily done in MMBasic) which just adds to the confusion.

Lastly, because the CFunction plays with the timers at chip level which screws up MMBasic. If you Control C out of the program or try to use the editor, the whole things locks up and needs a power down reset to recover - not nice.

I have started thinking about using an ArmMite H7 platform with the ArmMite version of MMBasic to interface to the Frequency Counter module as this platform, based on the STM32H743 chip, has a high speed counter input, inbuilt GPS string handling and should be fast enough to obviate the need for CFunctions. I will need to make a backpack to interface the Nucleo H7 module to an LCD and also to emulate the E100 GPIO pinout for interconnection to the Frequency Counter module.

Will soldier on - it will keep me out of trouble for a bit - not much else going on

OK, thanks for that Doug.

You obviously thought of posting this on the microcontroller forum?

keep at it
