Hi Jon,
To elaborate on Mark's suggestion, I include a python function I've
written to do just what you're trying to do:
def bramw(fpga, bname, odata, samples=2048):
b_0=struct.pack('>'+str(samples)+'l',*odata)
fpga.write(bname,b_0)
return
Where 'fpga' is your FpgaClient variable, 'bname' is a string that
contains the name of the BRAM, 'odata' is an array that contains the
data you want to write, and 'samples' is an optional variable that
specifies the length of data with 2048 being default.
Usage:
>bramw(fpga, 'Shared_BRAM', test_data, 32)
Best,
Laura
