Posted on December 18, 2012 at 03:22I'm programming for an STM32L152xx and ran into the part hard faulting when it goes to sleep but wakes up from an external interrupt. Since I need the lower power sleep mode, I'm doing the necessary steps to get t...

Posted on November 20, 2012 at 23:33MCU is an STM32L MD part. My application calls for optical-based software updates (don't ask if I can change it), and I'm at the process of writing that part of the software. I've been benchmarking how long it tak...

Posted on November 07, 2012 at 20:24I'm trying to verify that I can program an STM32L on the Discovery board using an external ST-Link V2 debugger. As far as I know, I only need the SWDIO and SWCLK pins (7 and 9 respectively) and ground. The SWDIO l...

Posted on May 09, 2012 at 00:56One of the areas I'm looking at with the STM32 is being able to transfer files (or at least data) from an IrDA dongle from Windows to the STM32. However, as I understand it, the STM32 only implements the PHY layer usin...

Posted on April 30, 2012 at 19:54I'm running into a strange issue where if I have the RTC auto-wakeup enabled, I intermittently get hard faults when I run the software through the debugger, break, then step through the code. Seems to happen more fre...
