Hi! I've got a product that we've just made a load of and while building out the firmware I realised that the INT pin on the LIS3MDLTR doesn't (at least according to the datasheet) appear to be able to be configured to show when new data is ready. Th...
Posted on September 08, 2016 at 17:52Hi,I have a problem where I'm trying to detect the presence of the low speed external oscillator, and to use it if it is installed. On bootup, it does the following: * Turn LSI on (it always defaults to off) ...
Posted on May 29, 2015 at 12:36Hi,Having had a working USB VCP using the old non-cube drivers, I've spent the last week trying to get a reliable VCP with the new ones - and failing. In fact at one point just uncommenting some irrelevant and unused c...

Hi.
I've been trying to enter STOP mode in an STM32F401with:
PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI);
When doing so, power consumption drops to 1.5mA so it's doing...
Hi Eleon,Thanks for the answer. This is for a low power device so I'd like to avoid polling if at all possible.Looks like I'm out of luck then. If I were to connect DRDY/INT in a board respin, is it possible to disable DRDY in software?

Posted on August 18, 2015 at 19:40Just to add to this, I was being stupid.It now works - I just had to get the board to stay out of STOP mode long enough for a USB connection to be established!
