Teensy boards are really slick, they're great small ARM boards with a lot of power. The audio filters and such here look great.

- AceJohnny2 12y agoHuh, I was additionally impressed that they could fit DSP functions on an 8bit AtMega microcontroller, but I see that's just the Teensy 2.0. Didn't know the 3.0 was ARM Cortex-M4 based! There's definitely more computation room there.
- diydsp 12y agoYes, but it appears from http://www.freescale.com/webapp/sps/site/taxonomy.jsp?code=K20_USB_MCU&cof=0&am=0#staticFile http://www.freescale.com/webapp/sps/site/taxonomy.jsp?code=K... that the MK20DX chip used on the Teensy 3.0 doesn't have the FPU and only clocks to 48 MHz. (3.1 clocks to 72 Mhz). A bunch of us have been having a blast for the least two years with the STM32F4 which contains the FPU and clocks to 168 MHz. See http://reddit.com/r/stm32f4 http://reddit.com/r/stm32f4 Nevertheless, this web user interface by PJRC is quite spiffy. I can see synthesizer design moving ever-so-slowly in this direction.
