The firmware can be uploaded to all OpenKNX-compatible projects offered in this online shop using this programmer.<\/p>\n
The programmer has a USB-C port (including ESD suppressor), a boot and reset button and an OpenKNX Prog button for conveniently switching to programming mode.<\/p>\n
The main board of the project is supplied with 3.3 V via USB when no bus voltage is present.
\nIn addition, in projects with 2x 3.3 V bus voltage supplies, it is also possible to supply the second 3.3 V rail via USB.<\/p>\n
For easy connection of a debugger, a 2x 5 PIN strip (1.27 mm), compatible with the J-Link \u201cCortex Debug Connector\u201d, is available.<\/p>\n
All OpenKNX-compatible projects offered here have the identical 2x 5 PIN (2.54 mm) programmer connection. The pins on the board are slightly offset so that the programmer can be plugged in directly without a socket strip soldered onto the board.<\/p>\n
No matter how many OpenKNX projects are ordered from this shop, the programmer is only needed once.<\/p>\n
If you do not want to plug in the programmer directly but would rather use a cable, you can order a corresponding 20 cm extension cable.<\/p>\n
A USB-C to USB-A and USB-C connection cable can also be ordered if required.<\/p>\n
If you want to connect both the bus and the computer to a board via USB-C via the programmer at the same time, it is recommended to galvanically isolate the USB-C connection to prevent damage caused by different ground potentials. For this purpose, the USB-C Isolator<\/a> be used.<\/p>\n Why is the programmer necessary?

\n<\/strong>Primarily for reasons of space: The USB socket (especially the modern USB-C version) is relatively large, as are the buttons for boot\/reset. There is also the J-Link debug connection, which is often very useful, and the additional power supply mentioned above. In order to keep the individual project boards compact, all of these things are "outsourced" to the programmer, which is inexpensive and only needed once.<\/p>\n
