If you don’t know, try the 64 bit and if it doesn’t work, the 32 bit. If you are running a 32Bit Windows: run the SETUP32.EXE installer. Go to Start > type ‘device manager’ > double click the first result to launch the Device Manager. If you are running a 64Bit Windows: run the SETUP64.EXE installer. How to install Arduino drivers on Windows 10. I also confirmed that changing the CPU for an STM32 obtained from Farnell on one of these boards fixed the USB issue. Older Windows Driver Version and Instructions. 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). Go to Tools > Serial Ports and if the FTDI drivers are not installed, you will not be able to select COM port in the Arduino IDE. Plug the FTDI module in one of your computer’s USB ports and open Arduino IDE. I did successfully get the openCM3 CDC example project to work in VSC/Platformio (after sorting out the STlink programming issue discussed in the link) and Macbeth got the USB to work another way, but as it stands the, it looks as though the current STM32duino code and these chips are incompatible. In both situations you need to install or update the drivers. I have not found any of the STM32duino code (including bootloaders) to work with these chips, whatever they are. I have tested my boards and the configuration bits at 0圎00FFFC0 are a match for Macbeth's when read using using ST-Link Utility, so the manufacturer as read from the chip is not ST if I understand correctly. Learn how to download and install the desktop-based Arduino IDE. While the discussion is about not being able to program STM32's with STlink, it turns out that the reason it doesn't work is because the CPUID was different than that which would be read from a genuine STM32 part. The link below, second page, has more on these boards. there may of course be versions of the chip with correct markings, not STM32) that that also don't work. However a compatible CH340 driver, your computer might be unable to identify this chip. Additionally, there is no programming required to access the processor on boards using this chip. Hi All, Thanks in advance, Ive bought STM32 for programming on Arduino IDE environment,but do not find the drivers, can you pl advise on the appropriate driver. Often FTDI drivers will be automatically installed by your system when using Arduino. I have concluded that while the boards were sold as STM32F103C8T6 system minimum boards and the chips are labelled as STM32F103C8T6, they are in fact something else with STM32 markings. CH340 Driver Windows 11 and Windows 10 Download The CH340 chip converts TTL (serial) to USB and vice versa on boards like Arduino boards. I was have been having problems getting USB to work with recent STM32F103C8T6 system minimum boards, getting 'device not recognised' messages and 'device descriptor request failed' message in device manager (Win 10).
