The initial polarity of the capture data was inverted (observed while doing a simple UART 115200 8N1 capture), this has been compensated by doing the inversion in the FPGA (https://github.com/360nosc0pe/scope/commit/6d8357538567ab1a5353a20817020e7b7bf018f2) but it also seems possible to do it in the HAD1511 directly, so we could maybe just use this and remove the support in the FPGA.
