What is Reddit's opinion of Embedded Systems with ARM Cortex-M Microcontrollers in Assembly Language and C: Third Edition?

From 3.5 billion Reddit comments

Can anyone find this book in PDF format preferably, thanks. Will pay $5-$10 https://www.amazon.com/Embedded-Cortex-M-Microcontrollers-Assembly-Language/dp/0982692668/ref=dp_ob_title_bk?dpID=51%252BE9C%252BHCoL&preST=_SX258_BO1,204,203,200_QL70_&dpSrc=detail

I learned to use STM32 microcontrollers in my college classes. My professor wrote a book about ARM Cortex M that I found helpful. He also has a website with some sample lab and info here that might help if you choose this route.

His lab info is based around the STM32L476xx instead of the STMF series.

The former is a fantastic book teaching you a specific microcontroller (but the concepts are not cortex-m4-specific). This is the microcontroller we used in my undergrad. You can get Discovery boards with this microcontroller alongside that book. STMicro makes a couple different boards for decent prices.
