Imagine for a moment that you’re in charge of a new scientific research project where a remote device will be deployed to automatically collect data samples and report back to the lab. The device might be deployed several times to different locations throughout the year, and one requirement is that a scientist back at the lab can send a command to actuate some mechanical device, like a motor, and respond with collected data or status at any given time. For a project like this, you’ll need to somehow wirelessly communicate with the device. These remote areas are likely well beyond the reach of cellular or other far-reaching radio signals.
This practical guide gives us an opportunity to take a relaxed approach to getting started with the TS-7800-V2 single board computer. We’re going to take a look at how to make our first connections, and setup the network. These are usually the first things we do before starting development. In the grand scheme of things, this is just a friendlier extrapolation from the official TS-7800-V2 manual, so be sure to keep it handy for more advanced topics and specific details. The only assumption being made is that you’ve purchased the TS-7800-V2 with a development kit, including the pre-programmed microSD card and necessary cables.
For you TS-7800 users upgrading to the TS-7800-V2, you’re in for a treat. There’s a migration guide specifically created to help you with some of the nuances in upgrading. For this, take a look at the “Migration Path” section of the TS-7800-V2 Manual.
When you’ve finished, be sure take a look at PWM Primer with the TS-7800-V2. Good stuff there about working with dimming LEDs and controlling servo motors.
Right then, let’s get started! Continue reading “Practical Guide to Getting Started with the TS-7800-V2”
In this PWM crash course, we’ll be taking a look at what PWM is and how to use it by way of example. First, we’ll control the brightness of an LED and make it breathe, then we’ll control the position of a servo motor. This will all be done using the PWM channels on a TS-7800-V2.
