Where thoughts show up as words
Hardware devices There are several physical devices on the tinysys carrier board. They require either one-way or two-way communication, each with its own bus type. The audio device uses an I2S bus to receive audio data from the FPGA fabric, whereas the SD Card uses SPI. Above all of this lives a software layer that […]
Previously on tinysys Last time I wrote some overviews about tinysys to slowly introduce the system, but I haven’t fully covered what it is that I am aiming to accomplish with a custom OS and a custom system design. In this part I will start doing that, and go bit by bit until we get […]
Multitasking on tinysys I wanted the hardware to be able to run more than one task at the same time (at the very least the device handlers and one or more other tasks), which meant that at the very least there had to be some kind of timer interrupt mechanism supported at CPU level. Luckily […]
