WebMar 8, 2024 · The watermark register is being set to 10, and so the number of data samples waiting (register bits FSS[4:0]) when reading following the interrupt will be at least 10, which I think is what you have (if you read the FIFO status before reading XYZ values out of the FIFO) ie not 2.It could be more than 10 depending on how long the code takes to … Web/* set FIFO watermark level */ lis2dh12_fifo_watermark_set (& dev_ctx, (cfg-> fifo -1) & 0x1F); /* set FIFO mode */ ... Without it the sensor will also generate watermark interrupts fine, but the acceleration value is always the same (reads the same FIFO item for infinity?). With this 10 msec delay strictly before enabling FIFO it is o.k.
WebIn this example, the samples bits are configured to a value of 6, causing the watermark interrupt to trigger when a sample is pushed into FIFO[5]. After a few more samples the interrupt is serviced, and six samples are read from the FIFO, bringing the number of entries in the FIFO to below 6 and clearing the watermark interrupt.
WebJun 6, 2024 · Hi, Ok. That is clear. Another question related to fifo pointers. For example I got SAI transmit interrupt based on FIFO watermark configuration. This means that there are still left data in a TX FIFO. I want to use I2Sx_TFRn fields RFP and WFP to calculate transmit FIFO free space. teaching family association conference 2019WebFree-fall sensing detects if the device is falling. These functions can be mapped individually to either of two interrupt output pins.
