Gets the value of the latency timer.It was an interface that launched a thousand hacks. Today the parallel printer port is on the brink of extinction and good riddance, some would say. A recurring element among many recent hacks is the use of an Arduino or other USB-connected microcontroller as an intermediary between a PC and an external circuit.
This is a reasonable approach, the parts are affordable and simple to program, but for many projects we can get by with just half the code, complexity and expense…and some folks will be thrilled to hear, no Arduino! This allows code on both the host and microcontroller to use much simpler asynchronous serial communication. As a size- and cost-cutting measure, some Arduino variants place this chip on a separate board to be attached only when programming the microcontroller, allowing it to be re-used for the next project.
An alternate mode, less talked about but no less useful, is bitbang mode. Any shop that carries the Arduino Pro or LilyPad, or some of the bargain-priced Arduino derivatives e.
Four data lines may seem constraining, but for many tasks this is sufficient; projects using SPI communication, shift registers and port expanders will be well served. Two software components are required to begin development: a device driver, which operates behind the scenes to handle all the low-level USB communication, and an API library, which is linked with your own code and forwards requests to the driver. Complicating matters slightly, there are two different APIs to choose from, and the setup process is a little different for each OS.
This library is proprietary and closed source, but they do not charge for its use, even in commercial situations. An alternate API, libftdi, is community-developed and fully open source. This library has similar capabilities, but different function names and syntaxes.
If you want to use the D2XX library, the header and object files are included in the driver folder. This is the easier option. Linux users: most current Linux distributions already have the necessary driver present as a kernel module.
The D2XX library for Linux can be downloaded from the FTDI driver pagebut libftdi is easier to install: simply locate libftdi-dev in your favorite package manager and have it take care of the dependencies when installing. The included ReadMe file will explain how to install this library. In a Terminal window, type:. Other operating systems: drivers for several other platforms are available. Please see the FTDI drivers page for details and links.
Bindings for other languages are available on the FTDI web site. Connect the resistor to either leg of the LED, but keep note of which leg is the positive anode side. If you plan on using D2XX, have a look at the second listing a bit later; the relationship between functions should be fairly obvious.
If the program successfully compiles all of the required headers and libraries in the appropriate locations, and properly linked with our own codethe LED should flash slowly. The code for such tasks will often be just as simple as the example above.
But when communicating with more complex devices and protocols, this byte-at-a-time approach becomes very inefficient. In the serial configuration, one simply calls fwrite to issue a block of data to the serial port, and the chip manages all the details of the transmission protocol: word length, start, stop and parity bits, and toggling the logic state of the TX line at the required baud rate.
In Bitbang mode there is no implied protocol; this is raw access to the data lines, and we must take care to construct a meaningful signal ourselves, essentially creating an image map of the data lines over time:. Suppose we want to communicate with a device that uses the SPI protocol Serial Peripheral Interface, also sometimes called Microwire, synchronous serial or three- or four-wire serial, depending on the implementation.
The required output would resemble the waveform in the illustration above: one output line provides a clock signal, another represents the data bits in sync with the clockand a third issues an end-of-data latch signal. SPI might be too esoteric for an introductory article; not everyone will have the right components around. Adapting this to libftdi is straightforward; see the first example for the different syntaxes. For a synchronous serial protocol such as SPI, where a clock signal accompanies each data bit, this method works perfectly, and hopefully that can be demonstrated in a follow-up article.Welcome, Guest.

NET automatically since there is no manifest. FTDI doesn't have anything available I managed to create the wrapper by hand which is a pain as i need to marshall the code in.
In short : all i need is the function prototypes for the MPSSE-SPI dllthe structure prototypes and a 5 line program - open device index 1 - retrieve its information block in the information structure and give the serial number and description as strings. Professional Electron Wrangler. Any comments, or points of view expressed, are my own and not endorsedinduced or compensated by my employer s.
For this one they have a C wrapper. This way you wouldn't have to deal with the SPI lib, at the cost of having to code on a lower level. I delete PMs unread. If you have something to say, say it in public. Well the point was to avoid all the bit thumping I'm pressed for time. That's not the one i want NET Thanks for the effort though I hacked it the hard way. I simply do not pass a structure, but a pointer to an array of bytes for the DLL call it doesn't matter a pointer is a pointer as long as there is enough room to plunk its stuff FTDI is a weird company.
I email themcall them. Nobody ever answers the phone. Email response is slow takes 3 days to get an answer. I have one direct number and the voice message says 'i am out until january 3'. They have at lest 3 revisions of appnotes and none match the driver version. The appnotes are full of 'for explanation of this see document that'. It is one massive puzzle. Rob Newbie Posts: 1. When I call that one, the program always gets stuck.
I suppose the issue lies somewhere in my import of this function from the DLL. Did you finished your work on that and if so, can you give me a hint or maybe some code you wrote? Here is my code, I currently use for the import. Its not your code.C library for controlling traffic lights on GlobalLogic automotive hackathon.

LPCOpen Libraries and Examples
It will work with displays up to x in resoluton. What is FT?
It is practicaly an graphic card for a microcontroller. It can control your display with touch and even play some audio over connected speaker. What display can I use for this? You can buy display on ebay, aliexpress or everywhere else. Is touch screen an option?
Touch screen is fully supported by FT Not just that, you are managing touch input with higher level with tags. How much processing power do I need for this chip? Well, you don't need any processing power from arduino.
Only processing power you will need is to send some data over SPI. The rest will be done on FT Is it there a library available for arduino? Yep it is! Is it expensive? Its pretty much inexpensive. FT chip is few euros if you want to make your own board so it's not a deal braker. Can I see some examples please? Off course. Here is the video on youtube. Get me more info! Well much is written on offical site: FT site Note! I don't guarantee that all code is correct.
If I make some mistake and the code doesn't work, please let me know. Let's start! First you will need to get development board like this and an LCD display like this. I will not go trough wiring, cause different options are available.
Download library here. Install library like any other you already did. If you didn't just search google for it or bing if you don't like google. Now create a new sketch and copy-paste this code, we will go trough code later: Code: [Select].
Code: [Select]. I told earlyer that you can choose different font for showing text.
Here is image to show you different fonts you can choose: Try to change font, its the 3rd argument in FTImpl. Everything remains the same, we just add to our display list some orders to show lines: Code: [Select].
So now you will say: "Hey you were talking about touch input in the first post!Pages: . Adopting more or less what I found in this lib I was able to connect to my arduino, but I can't send a command. Here is what I have so far of which only the writefile part doesn't work: Thanks a lot!
Code: [Select]. One annoying thing about the arduino, is that opening the serial-port in software may restart the arduino. You have to allow for the time the arduino would need to reboot after opening the serial port. You are probably writing the data while the Arduino is still rebooting. To fix this you can physically disable the auto-reset feature of your Arduino or just wait for it to reboot. Looking at your code, you seem to have other problems. You are using Microsoft specific stuff, so I don't know what exactly those functions do, but you appear to be constantly re-opening the serial-port file, which is a big no-no.
It is too bad that Microsoft seems to not give a damn about serial ports anymore. It's unlikely that MS will ever implement ioctl so that you can go above kbaud, and the.
Net serial-port stuff leeks memory With the limitations of normal Windows serial-port programming, you may just want to ditch it. There is a LOT you can do with this library, most of which you won't care about. I tried to add a 10 second delay to my code but it doesn't work either. I won't initialize the serial connection every time in the end, it's merely to test if i am able to send a command over it, which i don't seem to be able to. You should probably walk before you run. How about writing some C code to do what you want.
That way you can get one piece of code working at a time. Here is an example of my serial. This is what I have learned.LPCOpen is an extensive collection of free software libraries drivers and middleware and example programs that enable developers to create multifunctional products based on LPC microcontrollers.
