I think you’re aware of this already but for everyone else:

There’s different kinds of embedded. What traditionally was referred to as embedded is microcontrollers (e.g., 32-bit ARM Cortex M devices like the STM32 or an NXP IMX106x chip ). A configuration for a Cortex-M7 chip (that some may consider on the high end of traditional embedded) is a 600MHz clock, 1MB of RAM, and 4MB of flash memory. These run either bare metal or a real time operating system but don’t have an MMU.

These days the definition is sometimes expanded to include devices that run full fledged OSes like Linux (embedded Linux) on devices like the RPI with much more memory than an MCU.

To answer the original posters question a bit: get used to C and C++ and not using malloc() / new(), which includes a lot of the standard library.

I don’t think that is exactly accurate. But you know, like close enough, describes all my work. Just pointing out that something like an industrial system running win ce on PowerPC or x86 has been within the definition of embedded for a long time. Embedded Java was/is a thing. Both extremely non-central examples, but what’s new is how cheap the hardware is, embedded has always included more sophisticated OS’ and more than micros.

I'm still a noob but it seems like there's also a distinction between bare metal embedded and RTOS, which is higher level. I think STMs are more commonly run bare metal but esp32s use a version of FreeRTOS.

Also libc is bloat :P
