Parallax Propeller, why is it so overlooked?

What do you mean PASM is an odd ball? I ask because that is what im using to learn ASM, as I understand if you know one chip you pretty much can figure out ASM on any chip with a data sheet. Obviously the lack of interrupts are different, but what else?

I do agree spin was the worst part of the chip, although it is a nice language it maybe the learning cure higher. The fact that you can make a ton of counters or eight spi busses is really cool I like how nothing except the UART/EEPROM/XTAL pins are special purpose.

Ive read numerous things.  Such as this from http://forums.parallax.com/discussion/132966/propeller-assembly-for-beginners

1. There are 496 "registers" which may contain code or data. Certain constructs require operating on code as data (i.e. arrays in COG RAM).
2. Pipelining means changes to instructions don't take effect until the next instruction.
3. How JMPRET (aka JMP, CALL, RET) and DJNZ/TJNZ/TJZ work thus why you normally put an # before the label.
4. Flags - having to specify which flags get updated, the power of conditional operations, and the limitations of only having two flags.

After reading multiple odd ball things, I was waiting for the C compiler which was finally out of beta recently from GNU.

Have you seen the new propeller hat for the raspberry pi?

Wow! That is pretty cool!

I started down the path of creating a flight controller for a UAV using a propeller but I didn't make much progress (never any time!). I thought it would be great at overlaying an OSD over a video feed for telemetry and FPV.

Maybe when things slow down... 

It is too hard for some non programmers to understand internals here. Hence more ARM programmers.

C

What does it matter?  Either one you would need to understand internals with ASM.  If you are using C the learning curve would be about the same....  Confused.

Anytime you need to coordinate multiple processors, the troubles begin. I know this from working on big multiple CPU's at work. If totally independent, I agree no big problem.

C

That's the beauty, they are totally independent!  They are called COGs not really independent processors.  Its actually easier than using PThreads IMO.  Now they have a C compiler I may be trying mine out soon, but I really fell in love with the chipkit Pi so we'll see.

As I said I got my starts with a propeller and when I finally purchased an arduino already knowing C I wanted to do more powerful things and interrupts just seemed like an awful way to do multiple thing it throws determinism WAY off sometimes :/. I Use ARM base mcu's and AVRs alot, put I still think processing in parrallell is a much better pardaigm for small micros if exact timing is needed.

i have seen the prop hat and yes its cool, It extends the pi with alot of low level capability!

I also think learning spin is a PITA..... BUT people learn latter logic.... Spin was written especially for that multicore architecture. The Determinism is what makes the chip so great for robotics and industrial applications. I just wish id see it used more commercially!
