Getting Started with STM32F103C8T6 Blue PillDo not be suprised if you only see a DFU device. This is normal. Just compile and upload a blank sketch. However this is not the case. Normally manufacturers create composite USB devices in this case, i. But creation and certification of custom drivers for Windows is non-trivial and expensive. This method allows the use of 2 separate Windows drivers — both of which come as standard on all Windows installations. Although the functionality of both DFU and USB Serial could have been included in the bootloader, it would make the bootloader and sketch core code libmaple more complicated, as the sketch would need to communicate with the bootloader in order to send and receive serial data. So Leaflabs chose to go with the simpler option of the bootloader only containing the DFU functionality, and for the USB Serial to be compiled as part of the sketch. Although this is the simpler option, its probably the best one, because if the Serial USB support was contained in the bootloader, the amount of additional code to allow the sketch to send and receive Serial via the bootloader would make the overall size of the bootloader and sketch slightly larger. Another consequence of splitting the functionality, is that if the sketch crashes, then the USB Serial will also crash, and often the USB Serial device will not appear at all. And… any board that has been freshly installed with a bootloader, will only appear as a DFU device, because the bootloader checks to see if a valid sketch is in the program flash memory, and if not the bootloader continues to stay in DFU mode until a valid sketch has been upload.
But there was one huge drawback with it. Also the mini-USB port on the Development board was left totally unused. However this boot loader is still in developmental stage at the time of documenting this tutorial and is not advisable for critical applications. Make sure the boot 0 jumper pin on the board is set to 1 programming mode while uploading the boot loader. Once the boot loader is flashed this pin can be changed back to initial position operating mode. Step 3 : To download the software you have to enter your E-mail address and the download link will be sent to your E-mail. Then follow the link back to the website and click on get software again and you download will begin. The software will automatically detect the COM port if not use the Device manager and make sure you select the correct COM port number. Leave the rest of the setting as it is as shown below. Click on next. Click on close and exit the application. Make sure you select your correct operating system. Step 3: - Clicking on Preferences will open the below shown dialog box. You will get a DOS screen as shown below. Hereafter we need not toggle the jumper anymore to upload and run the programs. You computer should be able to discover the Board now. Wait for a while if you see any additional drivers getting installed. Also select the correct COM port according to the one on your device manager. The example program can be found at. Thus the LED appears to be blinking with an interval of millisecond.

I used the two batch files for drivers but WIN10 does not recognize the stm Message is no associated driver. Any suggestion? Windows 10 makes the installer go crazy because of the drivers. Is this the case of unsigned driver? You have to execute the batch file with admin rights. BAT File executed but the problem remains. I tried with 3 different win10 compiters. I am not able to change the driver and use a different one because. I tested this recently on a brand new W10 installation and it worked fine. Even if the STM32 was already connected. Some boards may have a hardware error that may not let your computer recognize USB, a pull-up resistor on the USB data line, see:. This is the board on ebay. I was have been having problems getting USB to work with recent STM32FC8T6 system minimum boards, getting 'device not recognised' messages and 'device descriptor request failed' message in device manager Win The link below, second page, has more on these boards. I have not found any of the STM32duino code including bootloaders to work with these chips, whatever they are. It also rather looks to me like a large batch of these particular boards with suspect chips is now in circulation, as I have 6 boards obtained in 3 different orders, 2 from UK stock and 4 in 2 lots from China direct all last couple of months though.
