  1. I have the LM3s9b92 evaluation kit and get the following error when I try debug it. Anyone know what is going on? CORTEX_M3_0: Flash Programmer: Timed out while writing to Flash memory CORTEX_M3_0: Trouble Writing Memory Block at
  2. Jeez.. that's a neat little project. Lucky for him to get his hands on a Stellaris LP.
  3. Hackaday post. Flurry of activity. Looks like everyone has been waiting for this.
  4. Estore Link. Max limit of two. Spread the word.
  5. Yes.. I like all this competition.. good for us. Also, I hear that their StellarisWare is pretty decent.
  6. Here is a link with those two stellaris launchpad boosterpacks in the list.
  7. The board has micro-SD card, USB host, USB-OTG,all ports break out on connectors and ARDUINO platform connectors. MAPLE support for F4 is on the way, so this board will be one powerful Arduino alternative
  8. Was searching for FFT libraries when I came across this player. Reads files from an SD card using FatFS by ChaN, displays a spectrum graph on an LCD using the FFT dsp library from Ivan Mellen. Mini-STM32 WAVE Audio Player.7z
  9. I was looking around for a general dsp library to do FFTs when I came across this page. Has a sh*t ton of stuff, hopefully helpful to you guys. Four groups of functions: Windowing function Fast Fourier Transform Complex magnitude (absolute value of complex frequency) Miscellaneous functions: logarithm(x), exp(x), pseudorandom generator Three library versions GCC ( Rowley CrossWorks, Raisonance, …) Keil MDK-ARM IAR Embedded Workbench Windowing functions (e.g. Hamming window) Windowing is very common step before FFT calculation Perform speed optimized windowing
  10. Choose as many as you work on.
  11. Thanks! Registered and submitted. Does it say "uk only" anywhere? I can't see it on the page.
