$40 for an ARM Cortex M3 microcontroller plus a color LCD touchscreen!
You don't need a programmer to start playing with it, as all STM32 chips come with a software bootloader, allowing for firmware uploading through UART.
Setting up a development environment is a bit complicated, but I've managed to get it working using the free Yagarto toolchain and a modified Makefile from this project.
Before I bought it, I found out on their site (http://www.powermcu.com/) that they are selling a new revision of the board (http://item.taobao.com/item.htm?id=5717559340) for almost the same price, so i asked them how much it would cost me, they said that it's gonna be $10 more.
I decided to buy the cheaper one on eBay and, to my surprise, they sent me the new one! :D
So here is my awesome ARM devkit running a preprogrammed demo:
Hello Emery,
ReplyDeleteI am impressed about all the information that you have on this blog and how useful is this for everyone who wants to fly "solo" with this kind of stuff.
I have exactly the same dev board that you present on this post.
I have been fighting the last weeks to try to run the LCD with no success at all.
I am using keil v3 and v4. Please if you have any projects or files working with this board i would highly appreciate if you can sen them to my email rherreradelgado@yahoo.es
thank you very much, and congratulation for such a great blog.
Roberto.
