FT232HL SPI Protocol(about Performance)
« on: October 15, 2023, 12:06:41 PM »

Hi, I'm Terry

I'm using FT232HL(USB to SPI / 1 Channel) and It's working.
Ubuntu 20.04
But I would like to ask for advice(about Perfomance)

Briefly explaining my code(C++):
----code start----

callback(from other process request, SPI_Write)

int main

  SPI_Write and SPI_Read --> to get data from chip(MCP2517)
  callback check

----code end----
I wanna separate callback and loop(two process work independently)
1 process (only check callback)
2 process (only only loop, not check callback)

Is there a way to do this using FT232HL(USB to SPI / 1 Channel)?

You may want to take a look at FT_SetEventNotification.

See the D2XX Programmer’s Guide.

There may be other FTDI Community users who have further inputs to this.
