Re: pyb.ADCAll() side effect

Hi devnull, You are right, shipping any lithium batteries is an issue - surface freight only. There are 4.8 mm coin batteries with solder tags available, but most are vertical mounting types, while on the WBUS-DIP28 the provided solder pads are or horizontal mount as there is not much space availabl...

Re: pyb.ADCAll() side effect

Hi, Still trying to find a plain 414/412 coin battery - not an easy item to find here in Oz (or anywhere it seems). A lot of the 4.8mm rechargeables I have seen appear to be obsolete, but I am still looking - there has to be a supplier somewhere (just not here apparently). This one looks promising, ...

Re: pyb.ADCAll() side effect - PYBD Battery

Hi pythoncoder.. I have spent a few hours today sorting out the back up battery on the STM32F722 and the WBUS-DIP28. What I have found is that the WBUS-DIP28 has provision for two backup batteries: 1. The RTC backup battery - this is described in the documentation as you say, with the circular pad a...

Re: pyb.ADCAll() side effect

Thanks chuckbook, yes that error in the script (which was an artifact from experimenting) was the problem with reading core_temp and it is now reading fine, but I don't really need that for my project. The documentation I had read hadn't specifically mention that it was the RTC battery ( I guess MC_...

Re: pyb.ADCAll() side effect

How lucky am I that two of the best on the forum have already done some work with ADCAll. My issue is not with the side effect you discuss, because I use external 16/20 bit ADC via I2C, so the switching of pins doesn't impact measurements. I am interested in using this because, like pythoncoder, it ...

Re: RSSI of connected WLAN

Thanks devnull, with a few minor modifications (to suit my coding style and calls direct to the WLAN) this has given me the information I need. Your help is appreciated.

Re: RSSI of connected WLAN

Thanks devnull

I will give this a try a bit later, it is similar to the route I was going anyway.

Does this routine run AFTER Wi-Fi is connected as a Station?

RSSI of connected WLAN

I am having some fun with the PYBD, transferring a build from a GPY to the newer STM32F722 device.. It all seems to work very well and is quicker and the code cleaner with the PYBD. To deliver the sensor information I am easily and repeatably able to connect over WiFi to a local access point and car...

Re: WBUS-EMMC how to tell if it's present

Wouldn't the usual way be to just try mounting and evaluate except? EMMC is definitely not a hot-plug device. I have not fitted my WBUS-EMMC as yet but I am interested in this topic because I will start experimenting soon. The WBUS-EMMC documentation states "This WBUS-EMMC replaces an SD-Card. It's...

Re: Prototyping board with 20-pin mezzanine plug/s

That would be a useful board as well I think. It would be good for breadboard experiments/development. I would still like to see something like a tile proto board though, to build one or more sensors directly onto. I am also suffering from the dreaded age related vision loss (especially fine detail)...
