RS-232 Interface Reference Example for LabVIEW FPGA
PrintOverview
This RS-232 example page contains three attachments of code (attachments not described in order of attachment but in order of creation). The original attachment is fpgaserialreadwrite_7.0. It is a simple implementation of a RS-232 interface using LabVIEW FPGA 1.0 (LabVIEW 7.0). It has separate examples for serial reads and for serial writes. This code was updated to the attachment fpgaserialreadwrite_8.2 to incorporate the LabVIEW Project. The latest attachment is fpgaserialreadwrite_8.6. This is an update to the previous two attachments. It adds in features like DMA and IO constants that weren't available in LabVIEW FPGA 1.0. It also combines the previously separate serial read and serial write examples into a single example program.

Is it possible to add more independents
serial ports in the FPGA?

cRIO has RS-232 port
CompactRIO has a RS-232 port, I would
imagine you can use the VISA drivers
running on the RT processor to
communicate using RS-232, this would
solve the voltage level problem.

Data Written Indicator
hi,
the data written indicator is by default
flase, so how will the data characters be
written into the FPGA memory as the case
will always be flase?...
Any answers
