CMSIS_5 VS Labrador

https://github.com/ARM-software/CMSIS_5/blob/develop/CMSIS/RTOS2/Source/os_systick.c bzw. dort https://www.keil.com/pack/doc/CMSIS/RTOS2/html/misraCompliance5.html#MISRA_1.

You can download the generic CMSIS files from here. The device-specific CMSIS header files can be downloaded from the Keil website: MDK5 Software Packs. Those pack files are ZIP files, btw.

CMSIS is Arm's own standard ("Cortex Microcontroller Software Interface Standard") for low-level software interfacing.

It's on Github [1], and rather nice. Vendor's middleware can be of varying quality, so just using CMSIS seems refreshingly nice!

Sure, have a look at CMSIS-DAP, FreeDAP, Adafruit DAP, and Blackmagic Probe. SWD will let you access the target's memory space (e.g. RAM, registers, etc). To program the device, you will need to interact with the flash memory controller and this aspect is microcontroller-specific. You can tickle the flash controller registers manually (easier but slower) or you can use specialized RAM-code to make the microcontroller program itself (more difficult but faster).

I launched a crowdfunded product back in 2017 that has kept going for the past 5 years, and I've never had this problem at all.

Random people email me all the time (at least 3-5 times per week, even now) with information about bugs/feature requests, or just to say hi/thanks and show off their projects made with it.

Comparing my site (https://espotek.com) to yours, yours is much more "corporate" looking and doesn't explicitly invite contact.

I've seen other people advertising their CRMs and whatever in the comments, but perhaps it's just as simple as openly acknowledging that you're one guy, the business is your personal project and people shouldn't hesitate to contact you.

There also is the Labrador [1] which you can get for $30 just the board so need to get your own clips and bnc connectors etc and print a housing from thingverse. I got one for somebody for Christmas so need to get the feedback but sounds like a versatile little box.

>It's just very hard to sustain a business on one-off low volume hardware sales so the prices on the official site are relatively high compared to BOM (but perfectly reasonable and necessary to sustain further R&D).

I run a low-volume open source hardware business[1] and honestly don't buy this argument at all.

So many OSHW businesses have absolutely woeful logistics that treats every single person outside of the US (or occasionally EU) as an afterthought.

This both what drives up the cost and pisses people off enough to create a sustainable business model for the boys in Shenzhen.

People aren't going to support your business if you ask insultingly high shipping prices or are constantly out of stock.

Holy shit I LOVE the Labrador, it's the most useful thing I have. Guys, if you're into electronics at all, buy one right now (https://github.com/EspoTek/Labrador/), it's amazing and only $30.

Also I'd say I'm sorry about the comment but that would imply I've changed but I'm still a sarcastic asshole. I'm working on it though.

AussieWog, bonus points for humility:

This thread is about Eurorack products, and you happen to sell a pretty sweet looking low-cost oscilloscope

https://espotek.com/

But I recently ordered a labrador from https://espotek.com/ which seems more promising (while still cheap).

I have personally contributed to Labrador and The Powder Toy. They were both quite friendly.

I open-sourced my commercial USB oscilloscope design (https://github.com/EspoTek/Labrador) after doing a bit of research into boards targeted at electronics hobbyists and crowdfunded by individuals or small teams.

Invariably, a community didn't form around the closed-source boards and they died.

A lot of people asked me what I'm doing to protect my IP from being "stolen".
