re: LCD dot matrix solutions with ultra-low-power MCUs
EREBUS0   10/4/2012 7:45:56 PM
Hi Mike, For the money, I have yet to see another development platform with the cost/performance and versatility of the MSP430. The level of IO control, interrupt servicing, timing, and performance control is truly awesome. TI provides excellent software support and documentation. If you do embedded work, you would be well rewarded by looking at the TI line of embedded processors. Good luck in changing world thinking, but we can only hope for enlightenment.

Erebus, Thanks for your comment. I fully agree with you that XY plotting libraries are nothing new. The purpose of this article is to show how processors which aren't typically thought of in LCD applications are actually quite capable of performing well with the proper system design and optimizations. An MSP430 is rarely the first processor that comes to mind when thinking about driving a large LCD, but my aim is to change that thinking. -Mike

If I had a dime for every time I have seen the basic xy plotting sofware re-invented for a new application, I would be a very rich man. Everything presented here has been done and overdone. XY plotting libraries abound. I wrote my first one in 1973. Little has changed, and it works quite well. I agree that using the MSP430 line can give you a good solid platform for building a user interface for embedded products. The timing and power control is awesome. Just my Opinion.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
