STM32 Programming Board

[Strange Tales]

Which board on Mouser do I order to actually program this thing (http://www.mouser.com/Search/ProductDet ... 32F405RGT6)?

There are like 7000 different STM development boards all with varying prices otherwise I'd just search this up quick. I have the middle man piece to connect the board to my computer through USB, but like a jackass I forgot the actual programming board (I need to load bootloaders).

Thanks.

are you saying you already have the st link? you don;t need a board if you already have that. you typically program smd chips once they are in place. you can do it with the st link OR you can use one of the dev boards in lieu of the st link because actually they all have an st link on them, that's how you can program the target on them.

You need computer-> stlink -> stm32 device.

that's it.

Really? Shit I didn't notice that. So I can solder the STM32 to the board, and then use the STLink to connect it to the computer that way? That makes things a ton easier then.

Thanks man!

So how easy are these guys to work? I'm pretty comfortable with uC's but I've never made my own board around one. It is something I've wanted to do for a while though. I was looking at the chip they use on the Teensy 3.2. They sell another little guy with the halfkey bootloader already on it so theoretically you could just build your own version of a Teensy. Is the st link you need at all similar to the pucks you can get to program PIC's?

Also if you don't mind me asking, what's this going into? I'm kinda curious!

I bought a PCB for a Mutable Instruments Warps that I'm going to try my hand at building. I know that Olivier has made a Linux MI boot environment that you can put the bootloader and firmware on the chips because hes a fucking wizard, but I just need to know how to connect the STM32 to my PC so I can put it all on there.

Dang, yeah that's pretty fucking nifty.

Pretty sure almost all stm32 dev boards with usb can be used as just a programmer after you start programming arm on another target board

[cloudscapes]

once you get into making your own boards for arm and other 32bit micros, unless you're clocking them really low, you start learning about ground fills. steep at first but worth it.

(not applicable for low speed dip versions of arm/pic32)

[cherler]

I thought you weren't supposed to ground fill on high speed digital circuits, maybe that was just for boards with more than two layers though?

[eatyourguitar]

you can do solid or mesh and then one sided or double sided or 4 layer. some people put a v+ mesh on one side with a ground on the other. with 4 layer boards you can have a 2 layer board sandwiched in a Faraday cage, all hidden via's and a harder to trace circuit providing some level of security from the lazy loafer.

I have not done any highspeed PCB design stuff yet but someday I will.

[cherler]

I do a v+ and a ground pour on my boards just for the easy routing. I've yet to do any high speed stuff either, so I'm going off stuff I ready on the internet once maybe here
