Hi Folks (and pardon me if I'm not on topic)- I'm looking for a way to synchronize some code activity to the Android display frame rate. It's a short bit of code that will simply set the color of a small display region, nothing more. Is there some sort of method or hook that I can exploit for this purpose? I can use a timer running at very fast intervals successfully but the renderin...

Used .id_table instead of .of_match_ta

I want to push a bit stream through a series of *identical* devices and have (identical) software running on each determine if that particular device is being addressed, or not. It seems like the simplest way to do so is to require each device to examine an address field in the packet and, if '0', assume the data that follows is intended for its consumption. If not, decrement the address ...

I need to reproduce a short audio stream with a Cortex-M0+ MCU (it's SAM D21E from Atmel/Microchip). The audio bitstream will be stored in an external SPI Flash memory (I need to manage many short audio streams, so the internal Flash memory is not sufficient). SAMD21 features DAC, SPI and DMA. The audio will not be high-fidelity. 8 bits at 8kHz sampling frequency is enough. I didn't m...
