Anyone ever use the HSI on STM32F103, how about RET6? I know the code is set up for HSE. I got it working, at least UART1. But now, the other usart devices ... Wondering if anyone has ever run into UART baud rate mismatches on using HSI? I have a few radios that work great with an existing driver and a diff design, but not joy on the F103RET6. I am using internal PLL, x8 (64Mhz) and 32Mhz (APB1, APB2) if anyone has any debug pointers that would be great. Its weird, the UART1 uses APB2, and others use APB1. I know I need the external crystal but I got these boards and no clock stuffed... (sigh)
thanks! -james
