Hello everyone,
i rencently bought some gd32f103cBt6 to replace the quite pricey stm32
I just drop the gd on a custom dev card i have - running with a 8MHz crystal. I had no problem uploading my sketch, working with the GPIO and the SPI but not with the I2C. I know it must be related to the timing difference, so would it work with a 12MHz crystal ?
Thanks for the help !

I did a bit of research and there are numerous reports of "strangeness" with the clone parts.

PS: Roger became so frustrated with the early Gigas that he pulled the support code out of the GitHub.

I do not think you have missed any critical items, but there have been numerous unhappy "clone" owners that have complained. Best to avoid these "almost similar" products unless you are just blinkin' LEDs!
