Interfacing the LCD1602-RGB display, bonus

By martinm, in Programming, february 02,2024.

Having successfully operated WaveShare's LCD1602-RGB display with a Yocto-I2C, we wondered if we could use the Yocto-I2C's built-in job system to read values from an I2C sensor and display them directly on the display without the intervention of a USB host. In theory, it's feasible; in practice, it's rather complicated, but interesting.

Interfacing the WaveShare LCD1602-RGB screen

By martinm, in Programming, january 12,2024.

This week, we're testing a small LCD screen manufactured by Waveshare which has the specificity of having an I2C interface. We don't have too many doubts about the possibility of interfacing it with a Yocto-I2C, but we expect that it won't be trivial insofar as display controllers like being difficult, and generally demand a proper initialization before agreeing to operate.

Displaying solar production on a YoctoDisplay

By seb, in Programming, december 15,2023.

This week, we created a small program that displays the current production of the building's photovoltaic panels on a Yocto-MaxiDisplay. To do this, we wrote a small Python script that retrieves production information from the building's Envoy S Metered gateway.

Migrating from USB to an Internet connection

By martinm, in Programming and For the beginners, october 20,2023.

Yoctopuce sells USB modules designed to operate when they are directly plugged into a USB port on your computer. But it is also possible to operate your Yoctopuce modules remotely via a network connection, using a YoctoHub for example. The Yoctopuce API was designed to switch from one mode to the other in a trivial way, so much so that we never thought to explain the principle clearly. An oversight we're now putting right.
