SPI serial output counter or latch?

Feb 15, 2005 1 Replies

Hello I have been writing some VHDL code for my CoolRunner CPLD. I am a beginner. I have made a project that counts events and sends them to a 16-bit counter. Currently I just look at the binary output.



I would like to latch the counts and serially shift the counts out as SPI In hardware I would use a latching shift register like a 74HCT165 and would use /PL as a chip select and tie CP to SPI_CLK and Q7 to a buffer then to SPI_MISO Nothing fancy.



So I guess I am asking if anybody has some VHDL code for a parallel in SPI out latch, or a SPI output counter.



Any help is appreciated. Martin



In Project Navigator 6.3i chose from the menu: Edit -> Language Templates -> VHDL -> Synthesis Constructs -> Coding Examples -> Shift Registers -> Parallel In, Serial Out
