If you have a 4k7 resistor ( marked 472 ) then do this: Thus combining the 10k resistor with the 1k8 resistor in parallel will give us a resistor with a value of 1.525k, which is pretty close to the 1k5 that we want. If you have a 10k resistor ( marked 103 ) then do this: We need to lower this value to as close to 1k5 as possible for the USB port to function correctly. As said above, your 'Blue Pill' may have a 10k or a 4k7 resistor on the USB D+ line. that you may need a 2k2 or a 1k8 resistor, but until now, have not said why. I have already hinted in the required item 6. (Use this formula if you have two resistors in parallel only) You can reduce the value of a resistor by placing another resistor in parallel with it. If you are equipped to do so, you can just replace the resistor with the correct value, but we will do something else, and learn to apply some electronics theory in practice as well. The surface mount marking for a 1k5 resistor is 152, a 10k is marked 103 and a 4k7 is marked 472. Your board may even have another value, who knows. This wrong value pull-up resistor causes the USB port to behave in an unstable manner, sometimes working, and sometimes not.Īs this is a surface mount resistor, it is quite difficult to read the value with the naked-eye, unless of course, you have supervision ) The correct value should be 1k5 or 1.5-kilo ohm, but most of the boards have either a 10k or a 4k7 resistor. This is especially true about some of the boards that were manufactured in China or elsewhere in Asia. Some of the 'Blue Pill' boards have a wrong value pull-up resistor on the USB D+ Line. A Magnifying glass, very good eyesight, or a Smartphone (to take a picture of a component and zoom in to read the value).

STM32 BLUE PILL WINDOWS 10 DRIVER SOFTWARE

If you own an ST-Link you can use its software or any other UART software that will allow you to upload a. If you don't know, ask me, but tell me your distribution first :)įor the Windows guys, I am sorry, I don't own a Windows computer, but I am sure you can find a windows version of stm32flash on google. Note: This will work for all Debian based distributions, but other Linux flavours, please use the specific command for your distribution.

STM32 BLUE PILL WINDOWS 10 DRIVER INSTALL

The needed package on Linux ( and also Mac incidentally) is stm32flash To install this, open a terminal or shell, and type sudo apt-get install stmflash and press. Since my primary operating system is Linux (Ubuntu to be precise) it is quite easy to find and install software, as it is normally just a sudo apt-get install xxxxx away ) Software to upload the bootloader to the 'Blue Pill' (You can NOT use the Arduino IDE to do this ! ) I use Cytron's UC00C USB to UART converter because the UART voltage is adjustable between 3v3 and 5v, making it possible to have only one converter that is usable on 3v3 as well as 5v devices.Ĥ.

A USB to UART converter ( Used to upload the bootloader to the 'Blue Pill'.) The STM32Duino Bootloader ( I will post a link on the bottom of the page to the one that I have used)ģ. An electronics breadboard ( Big enough to fit the 'Blue Pill'.)Ģ. To get this to work, you will need a few things, as well as verify a few things on your own 'Blue Pill'.ġ. For some, it is only required to load the boot-loader to enable this functionality Please note: Not all 'Blue Pill' boards will need a hardware modification. I will share that method with you now, as promised in the mentioned Facebook post. I am thus extremely happy to tell you that I have found, and tested as well as verified, a reliable method to achieve this. I have however done some more research, so you don't have to, and read through quite a lot of papers and posts on this topic available online. Īt the time of writing that post, I was however not confident enough that the method that I used to achieve that was completely reproducible by all my readers.

At the end of that post, I mentioned that it was possible to use the native USB port on the 'Blue Pill' to upload code via the Arduino IDE.

STM32 BLUE PILL WINDOWS 10 DRIVER HOW TO

In a previous post, I have shown you how to use the Arduino IDE to program the STMF103C8T6 'Blue Pill'.
