Comment on Nov 30th, at The usbstress software http: Firmware source is available. Here is another resource I used during my process of creating my own sdcc framework for the chip:. I plan on adding an example to that when I get a moment. Is there any simple debug strategy to check what is going on in the FX2?

What would be an appropriate waveform for both? What programming language will you be using for the host software?

On the driver side there won’t be differentiation between SX2 and FX2. There’s a project working on HID firmware: You just need linhx download the bulkloop example source and grab it from there. All programmed is done with SDCC. We’ll assume you’re ok with this, but you can opt-out if you wish.

I use the cycfx2prog utility.

First of all excuse me for my bad english. A company called AnchorChips now owned by Cypress came out with an innovative and useful product a while ago: For in-the-field product updates, or for developers, you can use a specialized second stage loader to write the boot EEPROMs.

Comment on Nov 19th, at 5: I think I can see how to control my own bus pretty easily by having the 8-bit data on one 8-bit output cypresz, and sending the control signals on the other port, and having the GPIF enable the control signals and do the timing. Their code is linuz pretty much the Keil code however, but with sdcc changes.

It can support all USB endpoints 30 plus control.

The code looks like: Anybody check out my fx2lib repository? The default iic file is found in the Cypress folder in the examples folder. You can follow any responses to this entry through RSS 2. Comment on Dec 5th, at 1: Both comments and pings are currently closed.

Comment on Nov 25th, at 5: I use libusb, and move the driver work into the actual software instead. Comment on Dec 15th, at 5: You can find the list link at http: It is Open Source and runs on Linux and Windows.


I have searched for its driver for Linux,but have not found it yet. There are a few things you can do. So, using the bit wide path, and having some of the control bits enable bus drivers, it looks like it would be very easy to control my external cypreas with just 2 driver chips, and not need any FPGA or other external logic.

Please help me to solve this problem. That is a FIFO write instead of read, but reads are generally simpler.

Comment on Dec 12th, at 5: I started by rewriting a few of the examples and libraries for testing.
