196: Software Server Thingybob

Aditi Hilbert (@HilbertAditi) spoke with us about MyNewt, an Apache-licensed RTOS and bootloader.

MyNewt’s Apache page is mynewt.apache.org and the github repository is github.com/apache/incubator-mynewt-core. In the README.md, check out the section marked browsing which points to the file system, ble stack, and assorted other source code goodies you may want to read. The secure bootloader code is also in there but as it is also a cross-RTOS effort (with Linux’s Zephyr), you can find the MCUBoot repository at github.com/runtimeco/mcuboot

Aditi works for Runtime.io (@runtime_io), a primary contributor to MyNewt. They work with companies who want to use MyNewt on their products.

We talked about OIC (openconnectivity.org) and using UDP endpoints over BLE. Constrained http is actually called constrained application protocol: CoAP (coap.technology). We also mentioned MQTT, an older standard attempting to solve some of the same problems.

The Apache license is one of the most permissive of open source licenses: choosealicense.com/licenses

175: How Hard Could It Be?

Jean Labrosse of Micrium (@Micrium) spoke with us about writing a real time operating system (uC/OS), building a business, and caring about code quality.

Take a look at the uC/OS operating systems (available for free to makers) and Jean's excellent and free RTOS books (it was the Kinetis one that talks about the medical process). Also, check out the uCProbe which integrates with your debugger to replace some logic analyzer and oscilloscope features.
