The files in Sourceforge are about the Sprockit, not to Rockit as described.

Thanks. I’ve thought about drum machines. I need a 27 or 28 hour day.

hello! really like the personalized look and good sounds these synths crank out! on the possible project idea maybe a good drum synth like the DCM8 except using a synth engine and not samples.

ahh, i love this – i’m looking for circuits to do an open tablet design that will, for one reason or another, need to use an STM32F for the mic, speakers and the webcam. mostly the reason for that is to reduce the BOM and the cost. http://rhombus-tech.net/community_ideas/kde_tablet/

would you be willing to help by pointing me at a more complete circuit diagram and allowing me to use it? i can do circuit diagrams in PCB CAD programs but i don’t fully grok what i’m doing (it’s been 25 years since i did electronics circuits at school). in particular, what values did you use for the RC circuit to smooth out the PCM input?

i literally need pretty much the exact same circuit, for the exact same reasons: an STM32F has only a 12-bit range on its DAC and its ADC, and there’s a limited number of pins so i have to use PCM for the volume control.

btw if you’re not busy and have some spare time and e.g. a leaflabs maple handy and/or would be happy to help out on a commission basis when the tablets go into production, i could really use your help.

Good choice.
I use boot ATMEL Studio 6 and ARM eclipse based IDE. For the ATMEL Studio, I don’t like the way they force the project folders and ASFramework to be used.

You should try Atollic TrueStudio: http://www.atollic.com/index.php/truestudio
The free version is a bit limited for debugging but overall they have very good features and plugins for professional development.

I got started with FreeRTOS and have been using it quite a bit lately. I really like the RTOS approach. I saw ChibiOS and it seems solid as well. It would be nice to do a comparison of the two, especially as it regards memory usage, code size, and execution.

Hi, I’ve been using http://www.chibios.org on various different STM32Fxx models for two years now and have been quite happy with it. The main developer of this RTOS works for ST in Italy although the RTOS itself is not supported by ST. It really eases a lot the development process by removing the “low-level” complexities of the architecture.
