    Re: Beware Of Counterfeit FTDI FT232RL parts

    I always got a laugh out of the feigned outraged by hobby crowd when their el cheapo Commie knock-offs didn't work with software not meant for their junk to begin with.

    The Rpi is a natural fit for the Prop and Parallax should have had rolled out a interface board when sales hit a million. Associating the Rpi with the Prop is a easy no brainer to gain...

    Doesn't matter what a bunch of us hobbyists think about Parallax and the P-2. What matters is will the P-2 be comparable to various ARMs, PIC32's, DSC's, to get the sort of design wins and...

    Your premise would be a good one if Parallax and the P-1 were serious players in the embedded world, but they're not. Hence I doubt if the industry cares one bit what Parallax says about...

    Re: Python on Propeller: many requests lately. . .

    Dirt cheap CPU cycles and near infinite memory pretty much squashed the need for fast, tight code.

    So it doesn't matter if a IDE takes a gig of RAM to run or for a OS just to start up. You simply...

    The popularity of Python for teaching programming is baffling - Pascal or Oberon would be better IMO. As far as embedded Python versions go, there only seems to be one for the ARM, no ports even...

    Look when the P-2 finally shows up in a year or two. It's going to be compared to multicore/minion processor offerings from Xmos, Freescale, NXP, and TI. Or Cypress's PSOC 5.

    At $30 it certainly provides a strong incentive to use a Prop or any other contemporary solution.

    The only way to resolve the RISCV arguments is to field test one of them with real world applications, which isn't possible yet. That's the problem with bleeding edge, it ain't there.

    What is to compare in regards to a cog based Prop and a LowRISC chip. One is basically a memory constrained microengine meant to do I/O grunt work and the other for general processing?

    They got the idea from Freescale with their TPU's used on the MC68332 and PPC automotive controllers - which also predate Chip's notion of cogs.

    That sounds a lot like the Sitara ARM with PRU's(cogs), TI already has one with 4 PRU's or some of the industrial strength MCU offerings from Freescale with eTPU's.

    Re: Is it time to re-examine the P2 requirements ???

    My bet is that LowRisc designers are expecting the "minion processors" to do the bit banging and grunt work the way the PRU's on the SITARA's and TPU's on the MC68332's(and now PPC's) handle it.
