Coming from the IIS2DH which had a simple threshold interrupt by axis that worked great. Can we achieve a similar thing with the IIS2DPLC? Specifically I want to do the following:If an axis exceeds a threshold value it will persist an output (INT1 or...
The actual sampling rates deviate from the published. For example and ODR of 25Hz is actually ~30Hz. Is this typical? We did not notice this on the IIS2DH part. I expected some variance from the desired rate, but is every device going to vary this mu...
I have an issue where the IIS2DH accelerometer gets into a state where I get no output form the axis registers. How can the device be reset without removing power? The IIS3DSH used to have a register that could be toggled for a hard reset. The IIS2DH...
Hi, I can only seem to read 10bit resolution despite setting the following:REG_CTRL1 = 0b00000111;REG_CTRL4 = 0b00001000;I have low power mode disabled and HR mode enabled, but the precision does not increase from Normal Mode.Am I missing something?
In fact, I found the issue to be rather simple. IF_ADD_INC was not enabled. Makes sense now. I am transitioning from the IIS2DH and I have had to adjust some small things like this ensure operation. I missed this one. Thanks -AP
Let me clarify how I measured this. I set the ODR to 25Hz and the FIFO watermark to 25 samples. I measured the time between interrupts on INT1.25 samples @ 25Hz is actually 44.78Hz.
6.8k.Correction, I was mistaken before. Earlier version was 3.6V direct to the IIS2DH. We now are in fact using 3.3v supply and I added caps to deal with the transients.
Perhaps, but trying to avoid excess components. Its a very small area. I also noted in earlier development that voltages below 3.3 would cause issues with readings. The low threshold varied with different chips, but transient dips would definitely ca...
