Re: [Emc-users] Rpi Pico
I see that Sparkfun now has them on backorder. Sparkfun shipped my order today. So that's good. Ironically Sparkfun had a limit of 100 per customer. I suspect you might find them being resold on Ebay. Yep. https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=raspberry+pi+pico&_sacat=0 Oh well.

I was thinking multiple RPi Picos to one RPi4, but for just one, that is probably the way to go. I'll try that first! The Pi Hat as the carrier board is also a good idea.

Re: [Emc-users] Rpi Pico
To answer some questions I looked it up... This is an STM32 microcontroller. The firmware makes it enumerate to a PC/Mac/Linux machine as a USB storage device. You program this this be drag-and-drop the binary file to the storage. (or do a "cp" from the command line) What software environment? You seem to have a wide choice. The Arduino IDE could work or you could use Gcc from the command line or STM' "STM Cube" but my favorite is Mbed from ARM. Some of the RTOS' would work too, like FreeRTOS. Supported input power 1.8–5.5V DC. Most pins are "5 volt tolerant" some are 3.3 volt only. This is basically a replacement fro the $3 "Blue pill" but I think this is done better and has MUCH better documentation. Read everything here https://datasheets.raspberrypi.org/pico/pico_datasheet.pdf What to do with these? I'm thinking they will have much more use on robot projects then on machine tool projects.But in the machine tool world they could be sued are a kind of "standard" that performs the same functions we see done by Mesa cards today but at a much lower cost.At $4 we can afford to place one on each axis. My experience with the M0 is that it is powerful enough to run PID controllers for two motors with the encoders are running at about 10,000 less per second and the motors are being controlled with PWM. You can to up to ~10 Mhz pule rates if you use the built-in hardware quadrature decoders. These do the encoder reading in hardware and a re much faster than software interrupts. But I think the M0 has only one channel of this. The main advantage of these vs. others is (1) good documentation, (2) trusted source, (3) low cost. About the cost. $4 is low but look also at the Raspberry Pi Zero. It costs only $5 and runs Linux. It is dramatically more powerful then this "pico" but Linux is just poor at "real-time" and the Pico is outstandingly good at "real-time".So they are complementary.It would be fun to build a $9 robot controller using both. I think I will. On Thu, Jan 21, 2021 at 8:04 AM Matthew Herd wrote: > Agreed. It looks promising, but no more so than a "Blue Pill" or similar > boards. Also, what voltages does it operate on?

Re: [Emc-users] Rpi Pico
No CAN bus port. No USB port. I guess it depends on how deep one wants to go into C programming as to what you might choose for independently controlled things like a tool changer. I have PIC32 development boards and processors that support quadrature encoders. Same dsPIC series with quadrature and CAN bus. The latest interesting and although a lot more money is: https://www.ti.com/tool/LAUNCHXL-F28379D With dual processors and a lot of other pretty cool features this could be made into a wicked pendant.

Re: [Emc-users] Rpi Pico
It has some interesting sub processors to handle I/O. Reminds me of the sub processors on the Beagle Board Black. https://hackspace.raspberrypi.org/articles/what-is-programmable-i-o-on-raspberry-pi-pico Here are some docs: https://www.raspberrypi.org/documentation/pico/getting-started/ It has a lot in a very small package for $4.00 Dave On 1/21/2021 10:41 AM, Jon Elson wrote: On 01/21/2021 02:43 AM, Sven Wesley wrote: For you people out there who use an Arduino or RPi to communicate with parts of the machine (tool changers, doors etc).

Re: [Emc-users] Rpi Pico
Agreed. It looks promising, but no more so than a "Blue Pill" or similar boards. Also, what voltages does it operate on? I wasn’t able to find that in the literature but I didn’t dig into their documentation that deeply. Nonetheless, it seems like info that should be part of the specs. > On Jan 21, 2021, at 10:41 AM, Jon Elson wrote: > > On 01/21/2021 02:43 AM, Sven Wesley wrote: >> For you people out there who use an Arduino or RPi to communicate with >> parts of the machine (tool changers, doors etc).
