LPC54608 Xpresso

Christmas came early for me this year! I managed to get a hold of some of the new LPCXpresso54608 boards.

What caught my eye was the combination of a TFT, external SDRAM, audio codec and a digital MIC. I had been looking for a good board to teach an audio processing course at PSU this Spring. It seems that may have found it. Last week at the Embedded Systems Conference I gave a technical session on utilizing the DSP instructions in the Cortex M4 and M7 cores. Since I had this board, I decided to make my own audio badge:

It was a quick demo of using the TFT with the DMIC and the ARM CMSIS DSP libraries. You can see I am plotting the time domain and the magnitude of an FFT in real time. It made for a very nice and fluid demonstration. I will have a spectrogram mode as soon as I get a bit more time.

LPC546xx family is looking pretty cool. I believe the LPCXpresso 54608 board will be out shortly for purchase through the common distributors. The new I highly recommend getting your hands on one. It is a nice board for playing around with the Cortex M4 core and doing some audio processing. The board also has Dual USB (a feature I like in the LPC43xx series), SD Card, Ethernet and 8 Megabytes of RAM. Not a bad deal at all!

Thanks for sharing Eli!

Any chance of a video of your spectrum analyzer? :-)
