Hello -I have an Accel 28 board made by Mikroe that has the LIS2HH12 device. As per the Mikroe data sheet I set J1,J2,J3 to positions 2-3. I have removed J5 so that line isn't pulled up.I've got the first 6 pins on the lower left up connected to my N...

Hello,I am using an STM32L031G6U6 device. (28-UQFN)Summary: There are 6 ADC channels configured for DMA. After having a nominal voltage (2.9V or less) applied to Channel 0 / ADC_IN0 / Pin 6, and then removing the source, the value remains in the regi...

Hello,Reading this thread I need a bit of clarity.I currently use mostly STM32L series controllers. On board builds I use PA13,PA14 to a simple 5 pin header along with VDD, GND and nRST. I use the ST-LINK pod to flash and debug. I'm using IAR EWARM t...

This channel has more filtering capacitance than the others, and after removing the source (or source goes to 0) it takes about an hour for the ADC register to begin falling, and takes about 10 minutes. I can take a lead that is grounded, touch that ...

Something I considered and tested. I used a 5 ohm resistor and grounded that input after disabling the supply and held it there. After going through the noted cycle as posted, still the value exists. It cannot be a capacitor holding a charge. If it i...
