ADC3101 and miniDSP Firmware

by Kelvin Posted on August 6, 2017

I recently added audio capture support to an Atomthreads-based product. I used a Texas Instruments audio codec, the TLV320ADC3101, for which I wrote a device driver from scratch for the Atomthreads real time operating system.

The ADC3101 contains an embedded programmable DSP called the “miniDSP”, which you can build your own firmware for and upload to the device at startup. One… Continue reading

RTOS for DaVinci DM365/DM368

by Kelvin Posted on September 18, 2013

Atomthreads RTOS now supports DaVinci DM365/DM368, the digital media processor from Texas Instruments.

dm368

The ARM9-based device comes with a wide range of source code and libraries for Linux, but there was previously no open source RTOS alternative for customers who would prefer to use a more lightweight scheduler. One of the major benefits of using an RTOS on the DM36x SoCs is to significantly reduce the startup time, from power-on to video recording.… Continue reading

STM8 RTOS for IAR Embedded Workbench

by Kelvin Posted on May 28, 2010

This week Atomthreads became the first RTOS to support Embedded Workbench (EWSTM8), the STM8 compiler launched by IAR last month. EWSTM8 provides a full professional-grade development and debug environment with support for hardware debuggers including the low cost STM8S Discovery platform. IAR offer a 30-day evaluation of the full version, as well as a time-unlimited 8KB “Kickstart” edition (with a few non-core features disabled).… Continue reading

Atomthreads: Free RTOS for STM8

by Kelvin Posted on February 20, 2010

I have just completed a port of the Atomthreads RTOS to the STM8 microcontroller. Anyone interested in running an RTOS on the STM8 can download the source code from http://atomthreads.com.

This has to be one of the easiest architectures I’ve ever ported an RTOS to. There are only six CPU registers and only three of these are general purpose registers for compiler use. Continue reading

Atomthreads: Open Source RTOS

by Kelvin Posted on January 20, 2010

Last week I released Atomthreads, a free RTOS for embedded systems. This project grew from a task scheduler I created some time ago and subsequently extended with semaphore, mutex, queue and timer modules. The result was a lightweight and portable set of kernel sources which can be dropped in to any embedded systems project to add a thread scheduler. It has been useful to me so I decided to open source it in case it proves useful to anyone else. Continue reading
