UART in PL

cazalet
cazalet over 8 years ago

Hello,

I try to realize a serial link

[1 bit start - 9 bits data - 1 bit parity - 1 stop bit]

with handshake between a microzed and a slave application.
Is anyone familiar with a version of RS 232 opensource IP Core that I could use or adapt for it in my PL side ?

note: I don't want to use the UART port possibility  in the PS because I want to try to manage until 8 TX/RX independent lines

(and I'm not sure the ARM uart ports can do the 9 bit data buffer )

    Hi there,

    In Vivado you can find the AXI_UARTLITE and the UART16550 ip blocks.  While the latter is fully featured, if you can use it, the LITE version will take up MUCH less resources.
    If you really need HDL and do not want to create this yourself, try looking at https://opencores.org/
    It is possible they have something that will interest you.
