Posted on June 24, 2015 at 15:26I am having a problem with STM32F100RC microcontroller related to the chip revision. It appears that TIM14 which I use is not presented in a new batch of chips. Old ones are marked STM32F100RCT6B rev. A and they work ...

Posted on June 29, 2015 at 15:18 I have checked the values. DEV_ID is 0x414 (High density devices) and REV_ID is 0x1003 (Y, 1, 2 or X). Reading the flash size register (at 0x1FFFF7E0) shows the chip have 256k flash memory. The chip can therefore b...
