Previously, both PXI and PXIe's R-series cards applied for two memory address Ranges. This is visible in the device manager. However, newer boards such as the PXIe7820 have only one memory address Range. This causes the previously developed driver under RTX to be unusable. For boards with two memory address ranges, the first is the range address of the MITE chip and the second is the access address range of the user FPGA logic. Access to FPGA boards in environments such as RTX and QNX can be accomplished based on the address offset generated by the C API.how can I do with the card only one memory range? Can someone give demo codes for the 7820R card?
