Re: Unable to get DHT22-example to work

I tried the DHT11 example on a Wemos D1 mini and got the same timeout error. Found out the silkscreen for D2 and D4 had switched places, when connecting the sensor to the correct pin it works. No idea why your results change when importing main. Have you tried to use the pin for something else than ...

Re: WiPy Timer

Hello, I had some problems with the Timers not so long ago, also trying the examples. Unfortunately, I do not see what is wrong in your code, but I can show what is working on my WiPy now. Currently using the Pycom firmware (MicroPython v1.8.2-103-g834e021), but will move to the official MicroPython...

Re: RFC: Moving forward with the WiPy/CC3200 port

Looking at the Pycom forum, my guess is they have more than enough to do with the newer boards. I hadn't expected much more activity around the WiPy, so this is good news! I have a few WiPys and think it is great if you are able to let it follow the development of the other boards for a while longer...

Re: External WiFi Antenna

You will also have to choose WLAN.EXT_ANT during initialisation of the network, or with the method wlan.antenna(). Have a look at the documentation here: http://micropython.org/resources/docs/en/latest/wipy/library/network.html I tried it using an antenna from a 2.4 GHz RC transmitter with better ra...

Re: Safeboot pin not working

Thanks Sebastian, that thread helped.

Had to change SAFE_BOOT_PRCM and SAFE_BOOT_PORT in mpconfigboard.h as well, then SOP2 and Uniflash seems to have changed the Safeboot pin. At least it boots without safebooting, haven't tried using safeboot yet.

Safeboot pin not working

Hello, I was trying the files from Dave in the rshell thread, but unfortunately I had a typo in the ip address in boot.py. To stop boot.py from being executed I connected the safeboot pin (GP28 on the extension board) to 3.3 V (also on the extension board) to enter safe mode. After that boot.py didn...

Re: rshell should now work with the WiPy

That makes sense now. I haven't really used REPL very much, but rshell seems like a good tool.
Thanks a lot for the files also, they will be helpful.

Re: rshell should now work with the WiPy

Thank you for your reply. boot.py did print two comments, but removing them made no change. Also tried updating pyboard.py with your changes and still get the same error message. However, I have the configuration of WiPy as a station instead of an access point in boot.py which will probably case it ...

Re: rshell should now work with the WiPy

I tried using rshell for WiPy, but have some problems. I have all the files in the same folder and have python3-serial installed. Python3 is version 3.4.2 and MicroPython on the WiPy is v1.5-1-ge954604. WiPy is not operating as an AP, and with a fixed IP of 192.168.0.14. Still using standard usernam...

Re: Logging ADC data to SD-card

Manitou, didn't see your plot before today, it illustrates it very well. Probably a good idea to store data in a buffer first. I want to find the different options for sampling and storing data at a few kilosamples for some minutes, so data will have to be written while still measuring. Also looking...
