Chuck, is this the case with stm32? Or any spi interface irrespective of mcu.
Chuck McManis
@ChuckM
@amitesh-singh it is a the case with the version of the SPI interface on the chip used on the 1BitSy. ST has an older interface that was used on some earlier (like the old F1 chips) that is a bit different in some ways. All of the 'new' versions have support for the automatic control of NSS or "multi-master" support.
Amitesh Singh
@amitesh-singh
@ChuckM aha, good to know. thanks
Amitesh Singh
@amitesh-singh
i have noted it down. i think i have faced weird behaviour on stm32f1's SPI before. i did not know that this was the reason.
@ChuckM "It is the way SPI works, it always clocks in a byte at the same time it clocks out a byte." -> this is what i have known from AVR experience.
Chuck McManis
@ChuckM
@amitesh-singh well the challenge is that SPI has a very limited "specification" which was intentional to make it easy to implement in just a few gates on a microprocessor. As a result you have hardware versions with varying levels of sophistication. Apparently the F7's version is more sophisticated still but I haven't had a chance to dig into that one yet.

I'm looking at the datasheet for the STM32F415xx and it's not the datasheet I'm looking for? I'd assumed that the datasheet, DocID022063, was what I was looking for but it has an overview of the various timers. Not the config registers and how they should be configured. Perhaps I'm missing something but all I can find is that datasheet and not a programming guide. Is there a programmers guide? Should I be looking for an M4 programming guide? I'd assumed that the timers etc were bolted on to the M4 by STM and not part of that manual?
John Whitmore
@johnfwhitmore
Nope that document I listed, the M4-Programming manual only deals with the core peripherals. So still searching for a document
John Whitmore
@johnfwhitmore
@AvianAmbassador_twitter - OMG if what I'm looking for isn't in a 1745 Page document. Thanks a million for that it's exactly what I'm looking for ;-)
Paul Fernquist
@PaulF8080
Be careful. I read the Ethernet section and later found out the chip model doesn't have that subsystem.
John Whitmore
@johnfwhitmore
I'm only on the basics of general timers so I should be OK for the time being. But thanks for the warning. I'll keep that in mind for future.
John Whitmore
@johnfwhitmore
Can the gdb debugger set a break point in an Interrupt routine?
Just trying to confirm that I'm getting into my Timer2 ISR and clearing the flag. gdb isn't getting to a breakpoint, but my LED is on suggesting it got in there.
John Whitmore
@johnfwhitmore
Forget that I forget that there's pullup on the LED. Ain't getting to the ISR.
John Whitmore
@johnfwhitmore
There's obviously not a great deal of traffic on this channel, so probably not the best place to post, however... About a week ago I added an example to the 1bitsy-examples project of using Timer2 to flash the on board LED. I was sure I'd created a pull request for my additions on github. I can't see any record of that pull request. I'm not sure it wasn't just dumped, in which case there's no point in my re-trying, or if I actually made a mistake in my attempted pull request, so it never happened. Anybody official got their ears on here?
HooperFly
@hooperfly
@johnfwhitmore ping @esden. He can probably help you with that.
John Whitmore
@johnfwhitmore
Thanks
Premature send. That sounded a bit abrupt. Thanks for that HooperFly, I'll try give @esden a shout.
Piotr Esden-Tempski
@esden
@johnfwhitmore I don't think I have seen a pull request from you regarding timer ... I will check in a sec
you might have sent the pull request to the wrong repository
it happens sometimes when you create a pull request on github that the dropdown by default points to the wrong destination
You have the patch you are mentioning in your repository here: https://github.com/johnfwhitmore/1bitsy-examples/commits/master
you should have feature branches this makes things easier especially if changes are needed before your patch can be merged up stream
Anyways thank you for making a new patch and trying to send it our way that is always very appreciated. The flow needs some learning but it is at the end very efficient on the maintainer side of things if done right. :)
Thanks!
Piotr Esden-Tempski
@esden
@johnfwhitmore anyways I just pulled your patch from your repository into the offical repo! Thank you for your contribution. :)
John Whitmore
@johnfwhitmore
Oops, sorry if I did that wrong, and thanks for the link. I'll go through that before next attempt.
Piotr Esden-Tempski
@esden
@johnfwhitmore yeah no worries. I did not find the pull request as you mentioned. So I just pulled your patch that I found. :) Thanks! :)

Is the Vin pin on the 1Bitsy 5V tolerant?

@adammhaile
Anyone have a TLC5940 library that works with the 1bitsy?
Maybe this could be adapted? https://github.com/PaulStoffregen/Tlc5940

Newbie question. I've connected my black magic probe and my 1bitsy to my computer's USB (a new Dell), which is running Ubuntu 16.04. I do not find the Black Magic probe in the output from dmesg. And likewise I don't see /dev/ttcyACM*. I've also created 99-blackmagic.rules according to the 1bitsy FAQ, also with no luck. Possibly, did I miss a step? @esden

@wmarone
is there anything in the output from dmesg?
