We really need a programming forum for things like this:Does anyone know of any GOOD tutorials for assembly language? I am particularly interested in using software to commmunicate with external ...

Before there was assembly, computers needed to be programmed by speaking their language directly with individual 0s and 1s.

What’s more, it is super useful to be able to read assembly from your high-level tools when something goes wrong. Of course, one of the problems is that each assembly language is different.

But you can get a great starting tutorial with the 21 programs on the ARM Assembly by Example website. You need a 32-bit ARMv6 or better — so Raspberry Pi will work here.
