You need an ISP device to provide microcontrollers with IDE compatibility

ISP programmers are essential if you want to program devices in the finished circuit. This is instead of doing so in a separate socket programmer. Because you can work with the final circuit, you can customise products in the later stages of the production cycle. Our goods might be for you if this is something that you want to be able to do.

Easy to program

There are many elements that make Arduino the incredible product it is. One of the most important however would be the way we easily program each board with the Arduino Software (IDE). It is simple to link it to your computer’s USB port and click the “Upload” icon. This begins an operation where you transfer your sketch into the microcontroller’s flash memory.

This behaviour happens due to a special piece of code. Said code is executable at all of the microcontroller’s resets. Furthermore, the code seeks out a sketch that is to be uploaded from the USB/serial port employing a certain speed and protocol. If it does not detect a connection, the execution moves on to the sketch’s code. This is what we refer to as the Bootloader. It exists in an area of the microcontroller’s memory. Specifically, it is at the end of the address space. You can’t program this as a standard sketch.

The right equipment

You need something particular to supply the microcontroller the compatibility with the IDE and program the bootloader. What you require is an In-circuit Serial Programmer (ISP). This is a gadget that links to a certain group of microcontroller pins. It does so to carry out the programming of the microcontroller’s entire flash memory. This includes the bootloader.

Something else the ISP programming process includes is the writing of fuses. This is a special set of bits that decide how the microcontroller functions under set circumstances.

At Kanda, we provide ISP programmers as well as accessories to go alongside them. This includes a programming adapter with ZIF socket and a 1 metre 10-way ISP lead. If you would like to know more about any of them, you’re free to contact us anytime. We hope to hear from you soon.
