Re: Strange floating point crashes

Hmmm, now Im chastened. Turns out this problem appears to be due to power consumption/drain on the digital output pins. I was testing with a small stepper directly connected to D2-D5/GND, as I do with Arduinos. With the stepper connected to Uno32 it crashes inside the divide function. With no steppe...

Re: Strange floating point crashes

More info: same behaviour with mpide-0032-windows-20121013-test on Windows XP. You can replicate this by getting AccelStepper 1.23 from http://www.open.com.au/mikem/arduino/AccelStepper/AccelStepper-1.23.zip, compile the example Bounce sketch. On UNo32 the sketch crashes and restarts as described af...

Strange floating point crashes

Hi, Im seeing non-deterministic crashing during floating point divides with Uno32 and mpide-0023-linux32-20121013-test and mpide-0023-linux-20120903 on both OpenSuSE 12.1 and Ubuntu 12.04. Testing code that runs fine on AVR Uno, I observed the sketch crashes after running for about 5 seconds (during...

Re: MPIDE 20121013 Test Build

Thanks to Brian for relaying this for me. Ill post directly now.... Host is OpenSuSE 12.1. trying to build the example Blink sketch. Previous versions of the mpide compile and upload fine, but mpide-0023-linux32-20121013-test the upload phase never completes. Final output from shift-upl;oad is: .......
