Re: MPLABX chipKIT Importer Plugin Released

Just wanted to say thanks for the importer - it makes debugging much easier, even with PicKit3's tenancy to slide a few instructions.

Re: Fubarino Software Reset

I suspect you've found out that Windows doesn't like USB serial devices going away and coming back again when they are in use. If the com port is open at the time the device disappears, Windows has problems reconnecting the device when it comes back - this happens even if you manually reset. I've be...

Re: Attention all you USB junkies!

Nice work!

<OT Warning>That makes MZs look a lot more interesting. What boards/chips are currently supported?

Re: Attention all you USB junkies!

Ok, is it just me or transferring CDC data about twice as fast as it used to be?

Thanks Brian - I'll give that a go in due course.

Re: Issues with SPI3 and interrupts

Of course, of course! I'd even looked at the interrupt controller for the MX7xx series and seen that there's just the single vector for the three interrupts. I'd just not realised that I should be setting the priority against the vector, not the interrupt source. And, when I put it like that it seem...

Issues with SPI3 and interrupts

Hi all, I am attempting to utilise SPI3 on a Fubarino SD (1.5). I'm attempting to do back to back transfers (as I'm trying to interface a digital microphone), so I'm not using DSPI. Additionally, DSPI only seems to support a single SPI port on the Fubarino despite it having 4. My simple example code...

Re: Confused by ADC?

I started with dumping registers, but something else took my attention! From a bit of digging around, it seems that things go wrong around the ISR stage if analogRead() is used. If I don't enable my ISR, things don't lock up. If I don't use analogRead(), things don't lock up. As part of my debugging...

Confused by ADC?

I'm confused by some behaviour I'm seeing on the Fubarino SD. I'm trying to use the ADC in interrupt mode, so it's configured to read 16 samples before raising an interrupt. I've had some success doing so. I wanted to get a baseline of DC offset, so I added a few analogRead() calls before I switched...
