Scenario that happens more often lately -- out for my daily bike ride, bent down &amp; pedalling hard into a headwind. Meanwhile some old fart passes me, sitting bolt upright, pedalling easily, not breaking a sweat. Kinda demoralizing until I notice that they&#39;re on an e-bike.

Last week I built up a new dspod board based on the STM32U3C5. These parts don&#39;t run fast - about 1/5th the speed of the STM32H7R3 used in an earlier dspod so one wouldn&#39;t expect much. There&#39;s a trick here though - the U3C5 has a new feature called the HSP that&#39;s designed to offload heavy math operations. I&#39;ve been trying some FFT-based spectral stuff on it and the early results are encouraging. It&#39;ll be interesting to see how hard I can push it.

I&#39;ve been using the Blackmagic Probe from @1bitsquared to do embedded development on Arm parts for years. It&#39;s a very slick bit of kit that supports so many devices and is tightly integrated with the Gnu Debugger (gdb). Recently I&#39;ve had several contributions merged in that support some new parts - the STM32H7RS used in one of my dspod boards as well as the STM32C542 on the Cheep4 module I mentioned the other day. If you do embedded, definitely give it a look. https://b...

Last week I spent some time adding yet another STM32 family to the @1bitsquared Blackmagic project. The STM32U3xx family is now supported for program flash and debugging (option bytes not yet). I used it to bring up a new member of my dspod boards today - all working just fine.

Like many folks I&#39;m concerned about the intrusion of AI/LLM/agents into software (and especially free / open-source) development for all the known reasons: ethics, deskilling, resource use, societal impacts, etc. but one hazard that I&#39;m not seeing people talk about is cost. Using these tools at the levels that are emerging as maximally effective is *expensive*, even factoring in that the providers are underpricing to capture the markets. 1/x
