Discussion - Software / 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)?

Hi, I'm Terry

I have a question about FT232HL SPI interface
I am using it to communicate with MCP2517 and SPI.

What is the maximum hz of SPI??

Hi guys~

I want to use FT232HL library at ROS(middleware), but there are some problem.
I confirmed that it works at the OS level using sudo commend, but middleware can't use it.

Anyone have a solution to this problem?
My PC enviornment : 64bit Linux, Kinetic ROS(middleware),

I am using USB to SPI function of FT232HL in Linux Ubuntu(ROS - middleware).
While using FT232HL, I took note of what I didn't know, and now I'm joining.
