How to connect the programmer and to identify the microcontroller We will analyze the programming steps with BitBurner as follows. Please remember that the ICSP programmer must be set so to operate at 3.3 V. The program is an elemental one: it appears with a single interface with four tabs, where it is possible to achieve everything.

The software application may be downloaded. At the heart of this program, there still is avrdude, but it is provided with a GUI (graphical user interface) that tremendously eases its usage. Of course, to use it via command line is not the simplest solution, therefore we would advise you to use BitBurner. The choice necessarily comes down to avrdude, an open source software application that must be used via command line. But that’s an elephantine application (especially in the last versions) and if you just need to upload the bootloader on Antennino, we strongly advise you to use a much lighter application. Some people use a software application by Atmel (now Microchip) that is named Atmel Studio. Īs regards the software, the possibilities here are manifold as well.

Let’s see immediately what we need in order to upload the bootloader on our Antennino: the programming requires a programmer with an ICSP interface (In-Circuit Serial Programming, that is, it enables the programming of the chip mounted in the circuit where it is used) and a software that manages it in fact a simple USB/serial converter (that is used when the bootloader has already been installed in the ATmega) is not enough.Įven here, there are different alternatives: one of them is the possibility to use a simple Arduino Uno as a programmer for the other Arduino boards, on which a specific sketch must be uploaded, we also need a 6-way flat cable, ending with a connector such as the one having the pinout indicated in Fig. Ruso also customized the RFM69 module’s library. In order to do so, Ruso had to add some code, therefore the size of the bootloader changed from 512 bytes to 1 kB, which decreases the space in the Flash memory (that may be used by the sketches) however, this sacrifice is largely compensated by the benefits of the remote programming.
There are many bootloaders for Arduino: you might even upload the classic one, that is commonly used in Arduino Uno, or choose the one used for the Moteino project, created by Felix Ruso: that’s one we believe is more interesting since it has the possibility to manage the firmware’s wireless update. This is because – as with all the boards based on Arduino architecture – Antennino provides a bootloader within the ATmega that’s a firmware executed during the microcontroller’s bootstrap stage (start), and that enables the execution of some preliminary operations, the most important one being the management of the uploading of our sketches, by means of the Arduino IDE and using a cheap USB/serial converter. Let’s resume the discussion from where we stopped, that is to say from the programming of its microcontroller, for the purpose of uploading the bootloader.
You learned about Antennino when reading the first part of this article, in which we presented the project and described the hardware, in detail. Let’s discover how to load the bootloader on our IoT board, so to prepare it for the usage.
