would you suggest to order(for free)  to able to be programmed via usb &with which IDE-IAR,Keil..?

thanks

Not sure I fully comprehend the question, the STM32F100 Value Line parts don't support USB.

Are you asking what development software to use for the board?

The VL Discovery board is supported by free evaluation versions of Keil, IAR and Atollic. They can program the part using the ST-LINK driver and functionality built onto the board. Which you use is pretty much personal choice, I'd recommend you try Keil, but you should try all of them for yourself. For lower cost, I've had good experiences with Rowley.

It's also possible to use GNU/GCC (WinARM) to develop code for the STM32, but the configuration/debugging is probably to steep for the beginner, but they are ''free'' if you don't value your time/sanity.

thanks

are you saing you cannot program/debug via PC connected to on board st-link usb connector(you need to get separate st-link in circuit programmer/debuger device)?

If so how about stm32f103(but I suppose it is not available as free sample?)

Which eval allows loading biggest program IAR,Keil?

No, what I said was that STM32F100 devices don't support USB. The ST-LINK portion of the VL-Discovery board works because it uses an STM32F103 part to program the STM32F100 which contains your application.

I believe they both support 32KB, you'd need to buy them if you want to develop a commercial application, or need more space.

The ST-LINK Utilities are not limited, you can use the entire space within the part, and use ''free'' GNU/GCC compilers.
