Why isn't this working?
Chris Gammell, founder of Contextual Electronics, explains his transition from hardware consulting to learning embedded firmware to stabilize his income. He details his personal project involving an STM32F030 and a 433MHz transmitter, highlighting the steep learning curve of moving from Arduino to bare-metal C development. Gammell and guests Elecia White and Dave Jones discuss the importance of hiring tutors, using build logs for debugging, and the specific frustrations of dealing with obscure Chinese components and complex microcontroller peripherals like SPI displays and I2S audio.
