Texas Instruments’ TMS470R1B1M ARM7-based MCUs with 1MB Flash memory have 60 MHz, 32-bit chips and also carry 64 kbytes of RAM. A High-End Timer (HET) co-processor provides greater accuracy in timing functions like period and pulse measurements, output compare and Pulse Width Modulations (PWMs). The HET co-processor runs independently in parallel with the ARM7 CPU, providing significantly higher throughput. Peripherals include two CAN controllers, five I2C modules, three serial communication interfaces, two serial peripheral interfaces and a 16-channel DMA controller.
Pricing for the 144-pin device starts at $14.95 for 1,000. For more information on TI’s ARM CPU, go to http://rbi.ims.ca/4927-550.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
