Posted on May 17, 2011 at 13:18A small update: On our channel 10 we had a 100K pull down resistor on the input. On channel 11 there was no pulldown R but a 100nF to ground. We realised that there would be a capacitor switching during the ADc sample ...
Posted on May 17, 2011 at 13:18I'm seeing exactly the same problem: // Sample Channel 11 ConversionComplete = FALSE; ADC_RegularChannelConfig(ADC1, ADC_Channel_11, 1, ADC_SampleTime_13Cycles5); // Select the channel ADC_SoftwareStartConvCmd(ADC1, E...
Posted on May 17, 2011 at 09:47I'm using a real 8Mhz Oscillator. I've also tried manually switching to the RTC clock before entering sleep but the problem is still there. The real issue I think is trying to ensure that all Pending bits on the WIU ar...
Posted on May 17, 2011 at 09:47baradkon, I have found if only one WIU is triggered before the sleep mode (in this small time frame) then all susequent WIU lines are ignored for wakeup as well. I believe this is due to all WIU lines being or-ed and w...
Posted on May 17, 2011 at 09:47Nobody fancies answering/investigating this one further? I'll just leave a warning to everone using un-deterministic wakeups on the STR912FA in sleep mode then - Don't use it! :p
