STM32F103ZET6 support

Postby Pito » Wed Nov 23, 2016 9:30 pm

Hi, let me ask the forum - is this ZET6 board

http://www.ebay.com/itm/STM32F103ZET6-M ... SwiCRUctZm

somehow supported today? I've seen on the wiki this "board also works" but not sure it is that one :)
Thanks,
P.

I have either that board or one very similar and the basics work OK.

I have read that there are some issues accessing all the pins, but I'm not sure why, and also some issue with hardware I2C, but this has not been verified.

So I think its fairly safe to buy, as even if there are issues they would probably not be hard to fix.

BTW. Why do you want to use that board, is it the RAM / Flash or the number of Pins etc

FSMC ? I don't think we have core or library support for that.

But the DAC does work on the V series, so it should work on the Z series

FSMC - sw is not difficult - just setting a few bits in regs when doing with sram for example.
What is difficult is you need ~40wires :)

Here is a board with 2x pads for a sram/flash on the bottom side.
I cannot find a schematics, however

PS: I've asked a few sellers, waiting..

The DAC works on the ZET6 board. I've tried it myself on my board.

This is my board.

I had to get hold of the STM32 application to burn the bootloader over the serial port and then I managed to use STM32duino to program it. The battery powers the RTC registers and the socket next to the battery fits an nRF24L01. I wasn't sure what it was, but connected one there and it configured (I did not test any comms).

This board is already in the wiki with schematics too: http://wiki.stm32duino.com/index.php?ti ... 32F103ZET6

Great!! Thanks! :o
I think the 10ns sram there is an overkill, 55ns would be enough, and much more cheaper.
It can execute out of external sram, afaik.
The stm32duino with 1MB of ram ;)

in truth, respect to the schematics doc, the extrrnal flash is different: it' X40, not X16.
I don't know about performance differences.. :)
