I've finally got my wipy installed in my car and on the first run of this code today I was logging 5 sensors to an SD card at about 3 sets of readings per second. I'm very pleased with that!

Re: Battery backed RTC on I2C bus
Excellentpythoncoder wrote:@scudderfish I've taken the liberty of adapting this for the Pyboard. I also added a mechanism for calibrating the Pyboard's RTC from the DS3231. https://github.com/peterhinch/micropython-samples.git

Re: Battery backed RTC on I2C bus
The onboard one is not battery backed and my wipy is ultimately going in my car where power and net connectivity will be intermittent. If it proves useful for someone else then that's quite fine.

Powering the Wipy
If I put 5V into VIN, is it safe to connect to a computer via USB?

Re: ADC Conversion
As Dave said (but in other words) uour two calls to lipo() will be returning different values. Call it once and assign it to a variable.
a=lipo()
a,a%4095

Scripting testing with pexpect
I'm editing code on my Mac, and pushing the edits to the Wipy using sitecopy. It was getting a little tedious reloading my new code and testing it via the REPL so I scripted it using pexpect (https://github.com/pexpect/pexpect) The only tricky bit was figuring out I needed to append '\r' to all comm...

Re: No USB port on OS X
Assuming it's an FTDI chip on the Wipy, try the driver from this page http://www.ftdichip.com/Drivers/VCP.htm

Quicker reading from multiple DS18X20 sensors
I've hacked about on the previous 18X20 driver so that it works quicker if you have more than one sensor. If you only have one, this will be no better. Basically, instead of enumerating over each sensor telling it to read, and waiting for an answer, I tell all sensors to start a conversion, wait for...

Re: Using sitecopy during Wipy dev
I tried with a node.js package (https://www.npmjs.com/package/ftpsync) in case compiling C code was too scary but it seems to disagree over file listing. I've uploaded a packet capture here https://www.dropbox.com/s/4z0mk1asfsc83c7/wipy-nodeftpsync.pcap.gz?dl=0. As far as I can see, the ftp client i...
