RE: STM32F107 on STM3210C-EVAL

[qber_ at poczta dot onet dot pl]

Hello.

As it is in description the main diffrences in STM32F familly are on-board flash and ram. So if you are using STM32F107VC you can use F103VC variant.

Between STM32F107VC and STM32103VD the main diffrences are in their periphelias:
3xSPI;2xI2S;2xI2C;3xUSART;2xUART;SDIO;USB;CAN                                                          STM32103
3xSPI;2xI2S;2xI2C;3xUSART;2xUART;USB OTG FS;2xCAN;Ethernet MAC10/100;one add timer    STM32107

As you can see here the drivers only you will have to support are for periphelias which are missing in 103.

Best regards
Qber

P.S.
Sorry for the first mail - some stupid mail box error.
