Has something really changed, or are the boomers just stuck in the previous century…? I’ve been doing electronics for a long time, so that jab hit home. I raised my hand and said: „Challenge accepted. Let’s see.” test setup I was already working on a PID regulator for a commercial project. Since commercial projects live and die by price, I picked the cheapest possible MCU that could still do the job: STM32F051 (Cortex-M0, 16 kB Flash). The rest of the hardware: DRV8842 H-bridge driver chip. Hardware setup: DRV8842 driver chip + STM32F051 ...
