u/Jash_Embedded

I genuinely thought I “knew embedded systems” because I used Arduino for years.

Then one day I opened STM32CubeIDE.

That was my villain origin story.

Suddenly people were talking about:

- registers

- DMA

- interrupts

- RTOS

- linker scripts

Meanwhile I was still proudly typing digitalWrite() like a caveman discovering fire.

Did anyone else get humbled this hard while transitioning from Arduino to actual embedded development??
