By enabling or disabling the EP’s peripheral interfaces, spk can also reduce development costs and accelerate time to market by creating a single platform that can be modified to deliver differentiated end-products.

The 16 KB instruction cache and 16 KB data cache provide zero-cycle latency to the current program and data, or they can be locked to guarantee no-latency access to critical instructions and data.

Their support seems appropriate for this question: The ARMT’s bit microcontroller architecture, with ep93xxx five-stage pipeline, delivers impressive performance at very low power. Looking for complete solution is OT on SO.

Due to the fact i was not using drivers but i was bitbanging bits directly in the micro register I had a collateral effect: Stack Overflow works best with JavaScript enabled.

First of all thanks for the reply. Note that the sensor in this case is “embedded” in the board itself. The EP is a high-performance system-on-chip design that includes a MHz ARM9 processor and is ideal for a range of industrial and consumer electronic applications.

That was the problem Solution: Enhance your users’ audio experience through Cirrus Logic’s hardware and software solutions: The example I provided in the question is working because there is always a “read” after a “write”! Cirrus Logic’s embedded processor products are complemented by a range of complete operating systems.

I’m using a board from Embedded Arm. Solutions Voice Playback Record Control.

High-Performance, Networked, ARM9, System-on-Chip Processor

This coprocessor greatly accelerates the ARMT’s single- and double-precision integer and floating-point processing capabilities, enabling the EP to perform high-speed mathematical calculations when encoding digital audio and video formats, processing industrial-control algorithms and performing other math-intensive computing and data-processing functions.

Software and Tools Software and Design Resources available by request. Are you testing the spi output? A two-port USB 2. Can we have some more detail on what you’ve tried, exactly?

Our approach to the problem is literally based on bitbanging the EP registers like in spj example provided by the Embedded Arm file tempSensor.
