Xilinx didn't seem to be much help, and didn't have an 8051 assembly version of the C code I could look at.
The appnote is here: http://direct.xilinx.com/bvdocsapp...app058.pdf I'd have to search for the C code, as it was difficult to find online. I wrote a simple assembly program for the PC to convert XSVF to DB statements, so it's not laborious at all now. The assembler can convert that to Intel HEX. I assume I need a way to tell the routine where the data is located, what pins to toggle, what registers and timers are available, etc., and thought I'd need to do that in the assembler source. If I can figure out what the C code is doing, maybe I can write the routines in assembler, but I was hoping for an easier way. |
