Posted on March 20, 2018 at 18:33Hi!Fairly new to programming and embedded software in general but I'm having a problem with interpreting the values I am receiving from the magnetometer registers.I'm able to get a value between 0 and 255 for each re...
Posted on March 21, 2018 at 07:58I know for lis3dh, the normal mode gives 10-bit resolution while the low-power mode gives 8-bit resolution. But for lis3de, both normal mode and low-power mode gives 8-bit resolution. So what's the difference between...
Posted on March 19, 2018 at 20:14I would like to make a waterproof microphone. I.e. I need it to withstand water spray from time to time and at the same time maintain functional microphone, not kill the performance completely.I therefore am thinking...
Posted on March 20, 2018 at 07:43FSS[4:0] contains the unread samples stored in the FIFO. So when the EMPTY is 1, the FSS[4:0] is 0. But when the OVRN_FIFO is 1, the FSS[4:0] should be 32 but it can't. So when FSS[4:0] is 31 we should check the OVRN...
Posted on March 12, 2018 at 23:50Hi,I am working on a project where we are using the H3LIS331DL accelerometer.I am trying to understand what is happening with the interrupts, because I see some inconsistant behaviour.I got the following samples samp...
Posted on March 09, 2018 at 00:18Hey! I am using the accelerometer LSM303AGR to read some acceleration values on external interrupt. If the threshold is overcome, and interrupt will be triggered and in the ISR, I am reading the FIFO of the accelerom...
Posted on February 21, 2017 at 18:07Hello,I am having an issue with the H3LIS331 thresholds. I have all the thresholds setup in high interrupt mode for all axis. The high pass filter is enabled, my range is 400Gs, my sample rate is 100Hz and my comm...
Posted on March 14, 2018 at 09:22Hello,We used the LSM303D and now we use the LSM303AGR for a roll and pitch sensor (+/-45°C).The LSM303 components are factory calibrated (cf. datasheet of the LSM303D, DocID023312 Rev 2) :'The IC interface is factor...
Posted on March 18, 2018 at 21:35I am using a LIS3DH to measure a machine's vibration, I understand that mems accelerometers are not usually used for this application, but nevertheless, I set up the acc to High resolution mode which gives me a bandw...
Posted on March 15, 2018 at 17:24Hello,Do you have any information about Vibration Rectification Error (VRE) on the LIS344ALH (2g setting)? Specifically, I am driving the device into saturation. During and following the saturation, I am seeing what ...
