Texas Instruments' TMS320F241 and TMS320F243 DSPs offer 8K of reprogrammable flash memory and control area networking(CAN). The TMS320C241 offers 8K of read only memory (ROM) and CAN. Machines such as industrial book binders that use multiple electric motors of myriad sizes can be interconnected using the CAN bus to link the DSP controllers within each motor.
Applications include motion control systems, robotics, transmission/hydraulic systems, power supply inverters, uninterruptible power supplies, computer numerically controlled (CNC) machines and automotive systems.
The TMS320C242 offers 4K of ROM, a serial communication interface, dual 10-bit analog to digital converters, and the needed pulse width modulations for controlling a power inverter. Typical applications for this device would be heating ventilation and air conditioners and home appliances.
The four DSP controllers also feature a fixed-point, 20 million instructions per second (MIPS) DSP core with a 50-ns single-cycle instruction execution time, enabling 1-cycle multiplication and addition operations. Additional on-chip peripherals include general-purpose timers, serial communication interfaces, serial peripheral interfaces and analog to digital converters.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
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.
