If you want a very technical illustration of why, as they say, hardware is hard, follow along as I debug a communications problem between Pickup’s two main chips. Day 1 I was working on the bus interface between Pickup’s MCU (the STM32) and its WiFi radio (an ESP32) only to find that the STM32 UART appears to be… pretty terrible, actually. It was getting all sorts of errors I’ve never seen on another MCU before. Even when I dropped the bus clock down to almost nothing, the STM32 corrupted bits o...
