Arduino for STM32

Just a small follow-up with this APM32F103CBT6 chip. I also tested running this chip at 96MHz with USB and it works too. For running at that speed it needs increased flash latency (from 2 to 3, FLASH_ACR register) and there is also extra divider 2 for usb clock. With those two changes and PLL multip...

Hi, just found this thread about APM32F103 chip. Recently I got STLinkV2 clone with genuine Geehy APM32F103CBT6 chip and it looks like the FPU is working for me :-) The chip looks like this https://i.ibb.co/6FfQyDZ/stlinkv2-geehy-APM32-F103-CBT6-small.jpg datasheets are available here https://www.ge...
