Hello,
I'm trying to modify the example code "stream to host" to achieve asynchronous cropping of the signal (length of cropped signal is the same).
There are 8 channels on the FPGA, and I separated them into to two groups, each written to a different FIFO. The opening of FIFO is based on the time when the data point is acquired (counted by the variable "sample counts").
The problem is, when the two FIFOs opens at the same time, the code works fine. For example in the "synchrounous.png" file, when "lower limit = 480" things work fine. However, if "lower limit != 480", both FIFOs stop working and I get error code 50400 (nothing is written into the FIFO).
Can anyone help me with this? I really can't figure out where the bug is. Thanks so much !!!
