Wow! It isn't just Arduino users who are agressive.
It all looks like hysteresis, band gaps, local minima and quantum leaps to me.
People (and companies) need compelling reasons to jump to new platforms and tools. The more tightly bound you are to a platform, the bigger the kick required to break free.
I personally think that the Arduino+AVR crowd are missing out of they stick with the original H/W, and would be better served moving to Micropython on a 32-bit platform with an IDE like uPyCraft for the low barrier to entry embedded platform...
... but that would require a very big kick to get them out of their rut.
I'm not trying to convince anyone to change from Arduino, I say 'use what works for you'.
However ... anyone who quotes a Arduino mantra by way of trying to claim that AVR is in *any way* superior to ARM Cortex-M is just begging for a rebuttal from someone like me who has the experience to know otherwise.
Let's take an example of a product dear to eevblogs heart, the 121GW multi meter. What is the MCU in that ?
Is it a AVR ? is it a PIC ?
It's only a multimeter, surely it doesn't need one of those 1000 plus page manual STM Micros ??
I'm sure a Mega328 is PLENTY, just find the Arduino 121GW 'library' and it's done ... 5 minutes with a $5 Arduino Nano board. Perfect! Just ask RMB.
OH HEAVENS!!! it's a ST ARM Cortex M3 processor !!
Now Dave was very tactful about why the designer removed the initial PIC MCU giving no reasons why that might have been so as to not upset anyone and I applaud his marketing skills.
Dave did however go on to rave about how the SD card facility made upgrading and other features very easy in this
outstanding instrument which had it been the original PIC would have required a cable, a PickitX or some hardware and lots of warranty returns for bricked units and angry buyers advertising in every online forum "to stay away from this junk".
The designers knew what they were doing
If I didn't already have a decent multimeter, I'd be buying a 121GW tomorrow and as it is I recommend the 121GW to anyone who asks me "what multimeter should I buy".
It's a no brainer, ... thanks to STM32.
