This is just a quick adaptation of the Arduino Ethernet example to control a couple of relays for an automated test setup. I hope the source code is self-explanatory. Beware that Arduino IDE 1.0.1 or later should be used – DHCP in the Ethernet library is buggy in version 1.0. I am using Arduino ADK,… Read More »
Symptoms: Boot OpenEmbedded Linux system (probably other distributions as well) with the network cable unplugged. ifconfig shows eth0:avahi interface with a dummy IP address Plug in the Ethernet cable – no changes in ifconfig. I expected DHCP to assign an IP address ifdown eth0 && ifup eth0 solves the problem, but is inconvenient and can… Read More »
I have spent a couple of days scratching my head while trying to configure USB network gadget adapter. The platform is OpenEmbedded Linux on AT91, connected to a Windows 7 PC. Here we go: The first small problem was that the network connection shows up as ‘cable disconnected’ in Windows. It is solved by putting… Read More »
On a related note to the previous post, here is a patch that enables the SerialPort.DataReceived event. It is not officially supported in the Linux version of Mono. This workaround works in the following way: When a port is opened, a new thread is started. It polls the port for incoming data and generates the… Read More »
I have been searching for a solution for the missing Mono libMonoPosixHelper.so library. It is necessary in order to use SerialPort class. The application I’m working on now runs on an ARM processor, Linux OS based on OpenEmbedded. I’m not submitting this as a patch because I’m pretty sure this is not the proper way… Read More »
