Re: [teensy41] help getting started
Not sure if this is related to my problem or not, but if I try mpremote without any arguments, I get this response: $mpremote Connected to MicroPython at /dev/cu.Bluetooth-Incoming-Port So, the default device is not my teensy (/dev/cu.usbmodem14401 or /dev/tty.usbmodem14401). So, if I try to do "mp...

Re: SSR recommendation
Thanks, I'll look into it. For now I'm leaning toward something like a Celduc SUL842070 SSR, which should be pretty safe.

SSR recommendation
I'm finding it surprisingly difficult to find an optimal SSR to safely switch a low-power 230 VAC appliance (air extractor) using a 3.3V GPIO. Ideally, this would be normally connected (so that when I power down my pyboard the switch is on). The best I could find is this: https://whadda.com/product/...

Re: Issues with data-logging on Pyboard
For the record, another option for logging sensor output during "short" experiments (up to a few hours) is to connect the board to a computer and have it just print out data as it is read instead of writing to a file. The computer can log this serial stream to a file using cat or something like it. ...

Re: Is pyboard v1.1 officially discontinued?
As pythoncoder suggested I contacted micropython.org, and got the following answer: We would love to manufacture more of the PYBv1.1. Unfortunately the STM32F405 is not available for a reasonable price at the moment. The lead times are only estimates and are at 62 weeks. I wish to tell you better ne...

Is pyboard v1.1 officially discontinued?
Pyboards v1.1 seem to have been out of stock at the MicroPython Store for some time now. It would be very useful to know what is planned for this version of the board. Should we expect that no new batches will be made officially? Will unofficial copies soon be the only option to get a pin-compatible...

Re: Did not read the small print.
This may be a stupid question, but is there any official word regarding long-term production of the pyboard v1.1?

Quantifying idle time when using uasyncio
I'm working on a moderately complex automated system to read/log a dozen temperature and pressure sensors, run a few PIDs, control a stepper motor, and print out status messages. Most of these processes run in a async coroutine. I'd like to minimize undue lags, and to determine whether I need to opt...

Re: Piping data from pyboard to serial to cat
That did the trick, and I learned something new. Thanks! PSA: a combination of cat+polt makes it extremely easy to monitor various sensors on the fly, be it in the lab or in the field, and offers a lot of flexibility (cf polt docs ). I wonder if this can somehow be done using Pythonista on iOS... Th...

Piping data from pyboard to serial to cat
I'm writing strings using pyb.USB_VCP() while my pyboard is connected to a laptop running macOS. I would expect that the following code would read this data and allow me to pipe it to another process, but no luck (cat remains silent). Am I doing something wrong? I'm looking for the very simplest met...
