I've spent several hours trying to communicate with the above controller using Energia but without success. I'm really hoping someone will take pity on me and offer some ideas!   The problem I think is with the drivers, or lack of them. I downloaded the driver zip as recommended by Github (EZ430-UART.zip) and unzipped them. If I plug the CC3200 into the USB port Windows tries to install the drivers but when I direct the driver installation wizard to the unzipped files it seems to think the ...

Is this the end of the Write, Compile, Download and see the results paradigm? We have all been doing it for years, what else is there?   The basic paradigm for creating microcontroller firmware is to Write, Compile, Download and See the results (WCDS). This long winded approach can be somewhat mitigated by debugging and emulation software but it still boils down to WCDS in the end. The Arduino is a very successful classic example of this and has thousands of lines co code written for it so ...
The WizFi250 EVB is the evaluation board for testing WizFi250 and prototyping development. WizFi250 EVB is composed of a WizFi250 evaluation board and a WizFi250 module.     Feature Identification Button Description   WizFi250 Reset Through this button, user can restart WizFi250 module. Function Through the function button, user can enter specific mode without AT Command. ♦ Factory Recovery : When doing Boot or Reset, press the button over 3.5 seconds ♦ ...
WizFi250 offers a quick, easy, and cost-effective way for device and appliance manufacturers to add WiFi capabilities to their products. WizFi250 provides UART and SPI interfaces which enable connections to any embedded design utilizing an 8/16/32-bit microcontroller via simple AT commands. WizFi250 is an ideal solution for organizations with limited or no WiFi or RF expertise, as it not only reduces RF design time but also removes the burden of testing and certification, allowing customers; ...
As far as I am concerned the ESP8266 is a bit of a game changer for the internet an microcontrollers and so I have put it together with the ByPic (the what?). Okay I will start again. ByPic is an interactive language that works through a serial interface using a simple USB to serial converter: So: Will give: Really, this is the output from the Mini-Max, pressing 11 will use the HTTP protocol to get the head sent by google that contains the current date and time. What is shown as the main m ...
A few days ago I posted my fail with the ESP8266 model ESP-03. I never got it working (as of now), so I moved to the ESP-01 model. It worked like a champ. I upgraded the firmware on the module as recommended on the web and connected to my wifi network without problems what so ever. At first I didn't pull up the rest pin and it kept rebooting, but after pulling reset up it worked consistently good. Left it overnight connected and it was responding to ping on the morning, I am pretty happy. Like ...
The earlier W5100 and W5200 chips achieved success by bringing the benefits of hardware TCP/IP protocol processing to low-cost applications.  The W5500 carries forward all the major features of the earlier chips; - Full featured 10/100 Ethernet MAC & PHY - Hardware TCP/IP Protocol Processing - 8 independent sockets - 32KB RAM buffer   New W5500-specific enhancements include a faster and more versatile SPI interface (up to 80 MHz) and ability for the host MCU to flexibly ut ...

Introduction As more and more home devices communicate across the Internet, security should be a concern. When there are hundreds of devices in a home, it may be extremely easy to correlate bits of information from multiple devices and rapidly make inferences about the home or the owners. No-one wants people to know when they are out of the home, or what devices they own, in case it attracts burglars for example.   This post addresses just one tiny aspect of the broader security topic, whi ...
A little more than a month ago a friend told me about a cheap wifi module. So I searched for this piece of wifi magic and founded the ESP8266 Wifi module. And it is really cheap. Depending on where you get it and the version we can say is between $5 and $8 for one module. Told myself I can spare $8 for this Wifi promise land so I ordered two for a little more than $8. Yesterday I got them, right away I got very exited!! On yes, new toy! First I realized that I ordered the ESP8266 ESP-03 model. S ...

blog entry #3   see also blog #1 Vehicle Simulator - VTR / RTR   and blog #2 Vehicle Simulator Project   This update shows the Car Cape running on a Beaglebone Black. Both vehicle simulator and vehicle recorder systems have been built and they communicate with each other fine over the CAN bus. We are still having a devil of a time sorting out OBDII communications with a real vehicle. This is the main reason for such a long delay since our last posting, however I figured w ...
The skull was working great connected usb to the PC. But I wanted it to be wireless. Since I have an Adafruit CC3000 breakout board available, decided to stick it in. Also a few years ago I made my own Arduino compatible board, based on the usbasp project and got the inspiration from the metaboard. My board end up beein a 5cm x 5cm board with Atmega328p which can run Arduino code.   The overview of the Internet of Skull now is like this.   With this architecture the laptop is just a ...
''Being smart is not about brain size.. it is about connecting the right amount of neurons at the right time ....'' ST has just unveiled the STM32 F7 the world's first Cortex®-M7 based MCU, result of a fruitful collaboration with ARM. Watch our interview of Renaud Bouzereau and Thomas Ensergueix, Product Marketing Managers at ST and ARM The STM32 ARM Cortex-M based 32-bit MCU family is already a reference for developers around the globe, with over 500 part numbers, from entry-level MCUs ...
