Did you get a F7 as well?

The price of the F7 boards is now not much higher then the F4

I know we dont have a core for the F7 at the moment, but as various people are looking at cores to support a wider range of devices, I think sooner or later F7 will get some support.

( at the moment you could probably build a HAL MX F7 core )

well i've browsed to page 11 before a search on stm32f failed to find anything.

i spot a 103vg, the following caught my attention
2-way FSMC bus leads, you can access TFT / DM9000 network module, the restaurant has a compatible module


seems it has the fsmc broken out twice, they quote having a display whilst debugging a network interface

bar that no f7's at all. doing a search yields 10 off for £530 and a single at $56, about 6%??

and of course discovery with STM32F746G or STM32F746NG, farnell have the same pdf for each.
so what the differences are ??

waveshare.com only their STM32F746IGT6, all 3 levels $60/$130/$150, the last 2 having 4.2"/7"/10" lcd available
the discovery disco with STM32F746NGH6 is $71 with a 4.2 display

The http://www.waveshare.com/core746i.htm looks reasonable value at under $30

agreed, its the board used with their extension mother board in the more costly products, $50 is with a 4" display., then 7" & 10"
stop making me drool ;)

i'd rather plug into the motherboard, seems neater and probably less prone to errors in counting pins or reading pin label through a maze of wires.

back to original board, there is a schematic of their stm32f103/f107 with nrf24 around, tf card is probably sdio, tft needs to be measured just to find supplies and look for possible matching interface displays.
spi flash? on which?
rtc battery is supplied, 32khz crystal is there, where's/what''s standard for an rtc?

my boards don't usually end up in a box ( of their own with psu etc ) :cry:

the waveshare wiki is quite a good source of info, not sure if the code is SPL or HAL.
by now most likely a mixture.
the last cdrom in a package from them had a cube hal file. wrong one though.
sent an email suggesting they could include the full set, reply suggested copyright worries.
all of them probably exceeds a reasonable portion as with book excerpts.
still a best subset of f1, f4 & f7 would provide for most boards?
adding SPL to those being even better.

from another thread, @ahull provided a link for a board from the same manufacturer
a bit of browsing later
http://www.dragonwake.com/download/download-stm32/stm32f407/STM32F407ZET6_sch.pdf

no vet6 schematic though :(

I ordered the VET6 from the same seller. I wrote him a couple of messages to send me some documentations, he attached the following files.

Unfortunately I cannot find any tutorial, or guide to fire it up. If I connect the board via USB Windows 7 says Unknown USB device, and nothing happens.

Does somebody have a quickstart guide on these boards? I would appreciate it.

the link i hinted at is

http://www.csun.co.jp/SHOP/2015120201.html

actually it was the site one. a search on f407 returns this board, click etc

then about a third down is a set of 4 links, sch, datasheet, ???? and an examples manual
if you go roaming with stm32f1on search or f42 or cortex m3 or arm from the side links, there's a fair bit of info.
pretty sure i've seen the pcb 'blotch' last night/v early am - j4 is top edge & 2/3 across, also the sch

Open Device Management , right click on the yellow triangles, go in Properties and open the Detail tab. Look for the hardware ID, must be something like USB\VID_xxxx&PID_xxxx, post it here or search in the net for it.

Thanks for the suggestions. I knew this method, but unfortunately it is not working. If I connect the device, I get a balloon tooltip (1), and if I click on it it shows a screen with Unknown USB device (2). In the device manager there is no device with the yellow exclamation mark, just an unknown device, with no id (3)
