![]() ![]() You have probably heard the word bootloader thrown around here and there and that is really just code that lives on the microcontroller and it allows you to reprogram itself using some other methods. The only thing that you need to know about a programmer is it’s a special piece of electronics that’s able to erase and reprogram the microcontroller. ![]() If you’re coming from a background in Arduino programmers might be new to you. So to program this without using the boot loader that’s built-in, you’re going to need a programmer such as the st-link v2. However, I wanted to be able to buy a blank chip and put it on my own custom circuit board, so, I wanted to know what it would take to program this without the built-in boot loader. The chip comes with a pre-installed boot loader to make it really easy to hook up over USB and program it for your first time through the Arduino IDE. So if you are already comfortable with the Arduino IDE and programming language and you really just want a performance boost you can pick one of these up and get started pretty easily. It is pretty much better or faster in every category. It has Arduino support meaning that you can program this using the Arduino IDE, if you really want and these things are incredibly cheap you can get them for about two to four dollars and after working with Arduino for a long time the specs on this blew me away. The blue pill rocks cortex m3 architecture more on that later it is a very minimalist design meaning there’s just the microcontroller and not much else on this board. So it is pretty common to see people reference shorter part numbers to abbreviate or generalize them. I think the most important parts are these first few digits here the f-103 and everything after that is kind of more of the technicalities like how many pins there are or what the footprint looks like. The part number tells us a lot about the chip. Unlike Arduino, stm32 doesn’t really have a whole lot of nicknames they’re almost always referred to by the part number themselves. The blue pill which is also known as the stm32f103c8t6 this is by far the most popular one that shows up when I am searching for starter stm32 boards and honestly I think it is just because it has a nickname blue pill. How to connect STM32 Blue Pill with Arduino IDE?.STM32 Blue Pill starting with Arduino core:. ![]()
