Please tell me whether there is something wrong in my code or in my connections. I’ve done it and it works! The following github has the Arduino sketch and Windows executable. There is also no source code or a way to dump the chip’s current flash memory. You also need to get a full dump of a HM firmware. This isn’t the firmware on the manufacture’s site.

Oct 24,  · Wiring Hookup RS Adapter Plug. RS to USB Wiring Orientation. Getting either the Prolific or FTDI adapters to be recognised by the machine is easy in both cases but the new board seems to have vastly reduced link errors on the FTDI adapter when used with auroramon. The main errors encountered are CRC errors reported in the.

Note that pin 1 is at the end where there is a notch in the plastic and an extra hole on the top. Anti-static precautions To avoid “zapping” your chip avoid handling it by the legs. I sit down at a bench, and use long-nosed insulated pliers to hold the chip by the plastic part, not the legs, to avoid destroying it with a static charge. Minimal wiring The chip pinouts are: Note that subsequent photos in this thread show an earlier version of the board with the decoupling capacitors further away, and the green wires as blue wires.

It is better to have the capacitors right next to the chip pins. There is also a 10 k pull-up resistor for the reset pin. Although the chip has a built-in pull-up, this appears to make it reset more reliably when downloading new programs. It has an absolute maximum rating of 5. At lower voltages not all clock speeds are available. For running at 16 MHz you need at least 3.

If you are using lower voltages you need to adjust or disable the brown-out detection. I am planning to run at 8 MHz using the internal oscillator, to save parts and space.

Allen Bradley Micrologix Connecting to the PLC Over a Serial Port or USB to Serial Adapter This articles shows how to connect to an Allen Bradley Micrologix or SLC PLC through the serial port. The procedure is also the same for the Controllogix and Compactlogix .

It is an opportunity for us to reflect on the language and ideas that represented each year. So, take a stroll down memory lane to remember all of our past Word of the Year selections. Change It wasn’t trendy , funny, nor was it coined on Twitter , but we thought change told a real story about how our users defined Unlike in , change was no longer a campaign slogan. But, the term still held a lot of weight.

Here’s an excerpt from our Word of the Year announcement in The national debate can arguably be summarized by the question:

Did I brick my Mini?

It comes with tracks, a pair of idler wheels and a pair of drive wheels. I added another pair of Pololu idler wheels and mounted the idlers on short sections of aluminum L stock. The drive wheels are mounted onto

Apr 03,  · Looking at schematics, both this programmer and the FTDI Basic use the FTRLSSOP chip and have same basic hookup except the DSR reset and LED Status. I can’t seem to get the IDE download to work. I manually reset the arduino and verified that my reset circuit works.

The most common fall into two different categories: The different controllers also can be broken into categories based on the type of data communications protocols used to speak to them from the sequencing computer. The main categories of communications protocols are: Critical properties to consider include are: Number of Pixels to be Controlled Number of Connectors and Number of Strings that can be Physically Connected Advanced Features Grouping ability to treat multiple Pixels as one RGB Ordering ability to correct the physical RGB order to match the software sequence order ZigZag Ability to treat physical strings as multiple logical strings Reverse order ability to reorder the channels on a string so the most distant one is the first channel Etc.

Generally you also need to add an Enclosure to the Pixel Controller to protect it from the weather. There are several ways to connect the Power wiring and there are also several types of Pixel Connectors that can be used to simplify the wiring. Disclaimers The standard disclaimers pertaining to the information contained on this wiki page are listed here.

These are selected Pixel Controllers and other devices from the various vendors with a mix of properties. Visit their sites for the latest information and to see their entire product catalog. Pricing is as of Shipping from overseas can be expensive, check with your vendor. It took advantage of the amazing ESP microcontroller which combines a full micro controller with a built in wifi interface all on a small form factor board with an incredibly low price. There are several variations of these controllers which are generally referred to as Pixel Sticks.

Its important to remember that if you are using older firmware Original release or 2. We made this easy to follow guide to help you with installing the firmware so you can start using the PC interface immediately. Install the firmware that you just downloaded but clicking the “install it” button highlighted in the picture below. Make sure you save it to a place that you can easily access such as your desktop. Selecting the firmware file and USB port The next screen you will see is the firmware update installer screen.

The 4in1 ESC connector is designed to work with the typoon littlebee ESC. BetaFlight Download. This board works best with BetaFlight software, which has a focus on flight performance but is still relatively similar to cleanflight.

The transmitter applies a fixed excitation current for each resistance range. In 4-wire hookup, different pairs of leads are used to apply the excitation current and sense the voltage drop across the unknown resistance, so that the IR drop across the excitation leads is not a factor. In 3-wire hookup, the transmitter senses the combined voltage drop across the unknown resistance plus two excitation leads. It also senses the voltage drop across one excitation lead, and then subtracts twice this voltage from the combined total.

This technique effectively subtracts all lead resistance and compensates for ambient temperature changes if the two excitation leads are identical. In 2-wire hookup, the transmitter senses the combined voltage drop across the unknown resistance and both lead wires. The voltage drop across the lead wires can be measured by shorting out the resistance during transmitter setup, and this voltage is then automatically subtracted from the combined total.

However, changing resistance of the lead wires due to ambient temperature changes will not be compensated. The relay closes or opens when the reading falls within the deviation band, and opens or closes when the reading falls outside of this band.

There are some aspects of the board however that make it unusable for future electronics, which should be reliable and cheap. Also the wiring can we a bit fiddly. Only the stepper drivers are still modules for easy replacement. Megatronics is based on many famous open-source products including: Therefor this product is an already proven design. It combines all major features of these board into a single board solution for more reliable 3D-printing.

Megatronics has a powerful Atmega processor with kB memory, running at 16Mhz.

FT232 USB to Serial Breakout Board for Arduino

In that project, I ran into several pitfalls: They can be found on eBay and AliExpress very cheaply. Also, they can be controlled without any specialized hardware — all that is needed is one GPIO pin. There are libraries available for many of the popular microcontrollers. This time around, I found a couple of interesting free LED control programs, which are both quite powerful.

The Alpha Clock Five White (Basic Edition): An awesome alarm clock soldering kit– featuring five crazy-bright, crazy huge ” alphanumeric LED displays in white. To take advantage of this serial port, you will need to have an appropriate USB-TTL interface, such as the FTDI Friend, Alpha Clock Five requires (and provides hookup.

Here is my edited file contents: Whether you are on a Mac, Windows or other system, the physical hardware setup is essentially the same. You can connect with a modified RJ cable or directly into the RS terminal block. This really is just personal preference. Good luck with your setup and Happy Generation!! Photos of Final Setup My inverter is mounted in the carport on the wall. There is a power point on the wall just nearby so I was keen to make use of this in the most efficient way.

When you have the Raspberry Pi setup with a keyboard, mouse and screen, you need to have a powered USB hub connected to be able to utilise all these different peripherals. Once you have remote access to the Pi setup via the wireless adapter , the only other cables or connections you need are: If we set things up this way though, we somehow need to power the device from another USB based power source.

I could have used the powered USB hub that was provided with the kit, but that means that there is a large power brick to be plugged into the power point on the carport wall, plus there is extra cabling to connect the hub to the Pi and then the hub itself. So I thought I would try something different… what about my spare iPhone 5 charger brick?

This is a very small USB charger but it works perfectly well. This would remove the need for the hub to be included in the deployment.

Talking to the Raspberry Pi with an FTDI Breakout Board

I finally got it figured out last night. I remember using an Arduino Uno to program them a little over a year ago. The two FTDI boards? I have one 3.

November 16, , I can think of a whole lot of words to describe HRD, but “basic” is not one of them. And if you are not interested in the digital modes, that module DM does not even have to come up. After you get your radio and CI-V cable and get the driver installed according to the instructions that come with the cable, you can download HRD and “kick the tires” for 30 days for free and I advise you to take full advantage of that time if that is the direction you think you might like to go. If you are having problems getting all of the pieces to play nice together, contact their tech support and you will get support just as if you were a paying customer.

My advice is to make absolutely certain that HRD works to your satisfaction before giving them any money because they will not refund your money under any circumstances. Their refund policy is very clearly stated on their web site. On the other hand Another alternative is the DXLabs system. The “look and feel” of DXLabs is totally different than HRD, but at the end of the day, it will perform many of the same functions.
