Re: New version of rshell with better startup for ESP8266 and ESP32
On macOS, I think the default is to have DTR inactive until the port is opened. If that is used by the ESP, then that might explain the reset-on-open behaviour.

Re: Single interrupt trigger performing callback function several times.
Still sounds like electrical contact bounce to me - resistors won't solve that. Google for "button debounce", e.g.

Re: bme680 adafruit on pyboard
Depending on how I2C addresses are exposed, the lower bit may not be an address bit - try 0x78.

Re: convert in HEX
Did you mean binary to hex?
Code: Select all
>>> mem=[1,0,0,1,0,1,0,0,0,0,0,0]
>>> ''.join(map(str, mem))
'100101000000'
>>> int(''.join(map(str, mem)),2)
2368
>>> '%x' % int(''.join(map(str, mem)),2)
'940'

Re: asynchronous wlan scans
I don't know how it works, but it looks like the code you're after can be found here:

Re: own IP address?
Thanks. Kevin, it's very easy to integrate any git repository into your own setup, e.g.
Perhaps not widely known due to GitHub's popularity, but git itself is a distributed version control system.

Re: A simple radio link between two Pyboards
Ok, got your setup going on two F407 boards. One thing I had to change is the connection rate: radio = NRF24L01(config.spi, config.csn, config.ce, config.channel, 32) radio.set_power_speed(0x06, 0x08) For some reason, my nRF24L01+ modules refuse to operate at 250 kbps, so I set them to 2 Mbps. Apart...

Re: A simple radio link between two Pyboards
Very nice! Some setup involved, but it looks like I have everything needed - looking forward to try out the stream version.

Re: ulab, or what you will - numpy on bare metal
I don't know what the status of ulab is, but here is some information about how external flash is used on the SF2/SF3/SF6. From the info at https://store.micropython.org/product/PYBD-SF2-W4F2 : 2MiB external QSPI flash with execute capabilities to extend internal flash Additional 2MiB external QSPI ...
