Fred - I asked the group early on today what devices will be targets for development, what devices do they use, what devices do they recommend. Do you have any input on this subject matter? Thanks. Really enjoying your presentations.
Correct. If you are sending small control packets, there will be no problem. If you are streaming large amounts of data, you will have to throttle the WiFi transmissions. The RN-XV's UART can work at 460800 baud. This is also discussed in the WiFly User Manual.
Yes. You can send as many as 1500+ characters in one WiFi frame. The output speed factor is determined by the baud rate you set the RN-XV's UART to. So, you may have a device that can only run at 9600bps, which means you have to throttle your WiFi packets. On the other hand, you can run at a higher baud rate, which will empty the WiFi buffer faster.
Fred, how do you suggest to synchronize the Wifi transmission (faster) with the UART one (slower)? I send data through Wifi from a laptop to the wifi module and send it further to the microcontroller through the UART port. Data size is some thousands bytes.
emohammed - it's an audio conference with a powerpoint presentation you can download and follow along with. You can download the slide deck in the upper right corner under Special Educational Materials.
Just building my problem solving box of stuff for now. There are no immediate projects that target Android. My interest is in having a remote console through a smartphone or tablet into an embedded system. That allows configuration, control and f/w upgrading.
Thanks for the confirmation DaveWR. I think most of us have extra displays laying around. You would have to add a 5VDC supply, an HDMI cable, a USB cable/hub. But this stuff is not expensive. Digi-Key and Adafruit have some cool accessories for the BeagleBone Black.
Fred, would a bootloader for the BeagleBone be appropriate? Care to teach a class?
For those of us who don't have an Android device, I see that the BeagleBone Black computer is just out at $45 plus accessories. It's Android 4 ready. This looks like a less expensive and more versatile alternative to a Samsung Galaxy. Any thoughts?
Industrial trade shows, like Design News' upcoming Pacific Design & Manufacturing, deserve proper planning in order to truly get the most out of them as marketing tools. Here's how to plan effectively.
The series now can interface with a wider array of EtherNet/IP-compliant hardware across many industrial sectors, including factory automation systems, plastic injection molding apparatus, and materials-handling equipment.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
