Yes, tried with a number of cards and both sockets. Cards were formatted Fat32 on a Linux machine with parted. They could be read by a Windows machine as well.

Geez, I move between C++, Python, Java, Scala . . . .
All those have the parentheses. Habit!

Sure, here you go. The Web output is like a REST/JSON response that gives a sliding window of readings:
{ "current" : 41.4, "log" : [ { "1514836500" : 47.9 }, { "1514836800" : 41.4 }, { "1514837100" : 39.5 }, { "1514837400" : 39.3 }, { "1514837700" : 39.1 }, { "1514838000" : 39.1 }, { "1514838300" : 38.9 }, . . . . { "1515066900" : 41.4 }, { "1515067200" : 41.4 }, { "1515067500" : 41.4 } ] }I also send the readings to Graphite so I have a historical view (attached).

I actually did exactly as you suggest, cutting and pasting from the code above. I'm really at a loss as to how to debug, as I've had no issues getting these adapters to work with Arduinos, Rasp PIs, etc.

Hi folks,
I had wired up an SD card socket from Sparkfun:
But I keep getting the message, even with multiple different SD cards, all formatted to Fat32.
"Uncaught Error: Unable to mount media : NOT_READY at line 6 col 41 console.log(require("fs").readdirSync());"I triple-checked all the connections, and then used a meter to check connectivity, power, shorts, etc. They were all correct.
So I figured it must be the socket. I removed it and soldered this one on in it's place, figuring that perhaps the added voltage regulation circuit might help:
But I still get the exact same error message. Am I missing something obvious here? Again, I checked all the connections and they're fine. I have a DS18B20 connected to different pins and it works great, so the Espruino appears to be fine. Test program for SD card looks like this:
function onInit() { console.log("Connected!"); // Wire up up MOSI, MISO, SCK and CS pins (along with 3.3v and GND) SPI1.setup({mosi:B5, miso:B4, sck:B3}); E.connectSDCard(SPI1, B6 /*CS*/); // see what's on the device console.log(require("fs").readdirSync()); for (var i in files) console.log("Found file "+files[i]); var f = E.openFile("log.txt", "w"); f.write("Testing 123"); f.close(); f = E.openFile("log.txt", "r"); f.pipe(console.log); f.close(); }
Wondering if anyone has had a chance to follow up on this?
Thanks
