Posted on December 26, 2012 at 21:55I'm running an external 26MHz xtal (10ppm) in HSE mode with the right multipliers/dividers to clock my STM32 core at 71.5MHz. Which works great. In addition, I have PA8 configured in MCO mode to drive said 26MHz c...

Posted on December 27, 2012 at 20:41Hi Clive, I do see 26 MHz on the MCO pin in both the working and non-working case. We used the extent of our 200 MHz Tek scope to characterize this signal but cannot detect or measure any difference (even in windo...

Posted on December 27, 2012 at 19:17Well of course I have PA8 configured as a 50MHz push-pull, alternate function with a pull-up. As I said, it will work to successfully clock the radio chip so the GPIO pin configuration is OK. Other I/O pins in use...
