I am trying to shift my career to the embedded software world.

我正在努力把职业生涯转向嵌入式软件领域。

I learned about all the peripherals like ADC, USART, SPI, I2C, DMA, timers, and all on an STM32. (All bare-metal using CMSIS. I tried to avoid HAL.)

我在STM32上学了所有外设，比如ADC、USART、SPI、I2C、DMA、定时器等等。（全部裸机用CMSIS，我尽量避免用HAL。）

Currently , I am working on a preemptive processes scheduler, but still, I don't understand how to break into the industry. There is so little info about it online ; I know it's pretty niche and all . It would be great to get some insights from an oldfag in the industry and probably some resources.
