Virtual Hardware Platforms: Test & Debug Software Before the Silicon is Ready

Historically software could only be tested and debugged when the first silicon sample was ready, and the software team could not participate in the design process. But thanks to Virtual Hardware Platforms, software can be executed at speeds close to real time on an abstract model of the hardware, available long before a design has been completed. The virtual platform is designed to simplify the creation and support of virtual prototypes and allow design teams to begin developing software weeks to months before a hardware prototype is available, and software teams can use it as their application development platform. For example, Freescale is using a Virtual Hardware Platform for their new Vybrid Controllers to emulate both Cortex A5 and Cortex M4 cores, as well as peripherals and run OS such as Linux or MQX before the Controllers are ready (Q2 2012). One Virtual Hardware Platform has just won the ACE […]

TI SimpleLink GPS CC4000 Enables GPS For MCUs

Yesterday, Texas Instruments unveiled the SimpleLink GPS CC4000, a GPS self-contained module that can be interfaced with any MCU or MPU having a UART interface.  Due to limited resources of microcontrollers, several GPS features have been implemented in hardware such as the push-to-fix function which can simply be controlled by the MCU via a GPIO to receive National Marena Electronics Association (NMEA) strings containing location, time and velocity information. TI Simplelink GPS CC4000 enables GPS-based applications such as asset tracking, industrial M2M, sports and fitness, and precision timing. It can deliver better than 2.5 meter accuracy and provides pulse-per-second output functions to provide precise location and timing data. It can also automatically reuse previously decoded satellite information thanks to its “watchful-eye” feature in order to deliver fast time to first fix (TTFF) and optimize power consumption. Here are SimpleLink GPS CC4000 key features: Driverless, fully integrated GPS solution which requires […]

FSLBOT: Freescale (Dancing) Robot Kit

Freescale unveiled the FSLBOT prototype last year (and I missed it!), and today, the company has announced further improvements to the Freescale Tower System mechatronics robot and board, a bipedal robot and development board that allows designers to write software for a variety of sensor applications while making a robot walk and respond to touch, motion, vibration, tilt and other external stimuli. The new version of the robot uses a new programming language based on StickOS, has wireless capabilities and adds an Xtrinsic MAG3110 magnetometer. This robot has been designed with the collaboration of StickOS and CPUStick.com with the goal “to create a tool that would enable casual users and consumers of technology to become creators and innovators”. The Freescale FSLBOT Robot Kit comes with the following: Freescale Tower System mechatronics board powered by a 32-bit ColdFire MCU with 64K of RAM and 512K of flash. Leg mechanics and associated […]

Microchip Unveils Wi-Fi Comm Demo Board with 32-bit PIC32 MCU

After TI and Qualcomm, here’s another WiFi solution for MCU aimed at the internet of things (IoT).  Yesterday, Microchip Technology announced the Wi-Fi Comm Demo Board, which combines a Microchip 32-bit PIC32 microcontroller (PIC32MX695F512H) with a low-power MRF24WB0MA embedded Wi-Fi radio transceiver module. This small (and cheap) demo board can be used to integrate with existing embedded designs and/or to evaluate Wi-Fi connectivity with a 32-bit MCU. Contrary to TI and Qualcomm, the IP network stack is not implemented in hardware, but Microchip provides a TCP/IP stack that can be freely downloaded at http://www.microchip.com/get/A3VP.  This TCP/IP stack includes HTML, DHCP, DNS, IPv4/v6, SSL, etc… (See diagram below) The memory footprint is 28-34 KB depending on the modules used. I could not find details about power consumption, but the company claims their solution can also run with just 2 AAA batteries. Microchip explains that this solution can enable the rapid growth […]

Qualcomm Atheros AR4100P Provides WiFi Connectivity to the Internet of Things

In January, Texas Instruments was the first company (to my knowledge) to release a WiFi chip for the internet of things, the SimpleLink Wi-Fi CC3000, where WiFi is mostly implemented in hardware to lower power consumption. Now, the company has some competition with the announcement of Qualcomm Atheros AR4100P, an improved version of its AP4100 WiFi chipset, including IPv4/IPv6 support. The AR4100 targets the home, enterprise, smart grid and home automation and control applications that have lower data rates and transmit or receive data on an infrequent basis. The AR4100 system-in-package (SIP) features the following: Low energy Power saving modes as low as 5 µA Wake-up times as low as 2.2 ms Support for Quad SPI flash for faster wake times Low system resource requirements Low footprint host driver (25K Flash and 8K RAM) Simple, low-cost wireless system integration LGA package simplifies 2- or 4-layer PCB design Near zero RBOM […]

98 Raspberry Pi Boards Left for Qt Developers

In November 2011, the Raspberry Pi foundation announced that Nokia purchased codes for 400 boards from the 1st 10,000 batch, in order to give them away to selected developers that are interested in helping develop and test Qt 5 on the Raspberry Pi. This developer program is called QtonPi. The surprising part if that they struggle to distribute all those boards. Although to date 425 people have been selected, only 302 are currently eligible to receive a board because over 100 developers did not provide their details to receive the free Raspberry Pi board namely: Their full name The link to their wiki user profile. The area of the “QtonPi Accepted Page” where they are listed. The country where the board will be shipped If by chance, you are reading this blog, have been selected but you can’t see “OK” or “CODE SENT” next to your user ID, you should […]

Archos G10 xs Teaser Video with Sliding Keyboard Dock

Archos has just released a teaser video for its next generation Android tablet, the Archos G10 xs (xs stands for extra small). The video does not show much, except the concept of the new tablet which features a sliding keyboard where the tablet can be docked. Archos has not released the specifications for the G10 XS yet, but we do know the casing is made of stainless steel, is 7.6mm thick (12mm with the keyboard) and Archos has worked for 3 years on this design. There will be several models whose retail price should be between 200 and 300 Euros (Which would be between 200 and 300 USD in the US thanks to lower taxes). The new tablets will be powered by a Texas Instruments processor (probably OMAP 4) like the Archos G9 tablets and run Android 4.0 and Windows 8 depending on the model.
