Hi
Did you have some time to look at the Cypress request ?

I need to play around with motor controls due to a coming project
and I purchased the EB022 Motor Driver Board for that reason.
I would prefer to test on Nucleo F 746 ZG

However I couldn't find any example source code.
Any idea where to find further info and some jump-start code ?

Regarding INT Single Pin Interrupt with ARM

Hi

As you indicated the TIM3 can be reset with
TIM3->CNT = 0;

The reset pulse is external and in my case very short.

I have tried to use pin A6 to start an interrupt that calls a macro
doing just this
TIM3->CNT = 0;

I have been looking at the ...

I would like to test the new SK-VGA-III by sending serial commands.

the 4G manual says


By default, each module shipped from the 4D
Systems factory will come pre-programmed ready
for use in the Serial mode.


But I can't find anywhere what baud rate the unit requires

I guess that is hidden in ...

Thanks for info.

Now, just a basic question: I want to use the display in a very fast process

It is my guess that it will work very fast as long as the UART buffer is not saturated,
and the transfer to VGA will then take place in the bakgroud

Is that right ?

What is a normal NUCLEO UART ...

I can't find any UVGA III component.

Is it any of the 4D -
EB076
EB076v2
EB075 ??

How related and compatible are the different 4D components ?
Is there an example file using UVGA III with ARM ?
Instruction how to connect SK-VGA-III without using the obsolete EBLOCK EB071 ?

EB071 was a very nice E-block, unfortunately not more in production.
But Matrix has already developed the C-code for it.
It seems that a UART hardware port is used

Is it possible to use it under Flowcode 7 & ARM ?

There is also an upgrade to EB071 - it would be very nice if it could be easily ...

Some jumpers were found and the red lines are my guesses for correct settings
Still it doesn't work. I give up for now.
If anyone has an idea it would be most welcome
Thanks and best regards

Trying to use the Diplay Component OLCD Adafruit 4x20

The actual component used is this
http://www.mouser.se/search/ProductDetail.aspx?r=763-NHD-0420DZW-AG5

The diplay is dark, but by touching some of the open connections with the finger
fills the rows with random signs. It confirms that power ...

Thanks for the idea! Digilent-410-212

The Flowcode UART code has two connections TX, RX
and the Digilent unit has 4 connections TX,RX, RTS, CTS

Should RTS, CTS just be connected to GND ?

Trying to get UART functionality with

ST-link USB or
Eblock 039

This simple example compiles OK with USART2 and USART3
but not with USART4 and above

The Eblock 039 has a special driver and it installs OK, but when connecting Eblock 039 over USB
it doesn't appear among the COM ports ...

Could the test program be written differently ?
It should work - might just be some small detail missing.

Yes, everything seems OK

Still, I can't serial-communicate with PC over USB
That's why I keep searching for something that might be missing


The solder bridges SB4 and SB7 should be removed, but if pin D8 D9 are not used,
they could probably stay

I have been looking for a back plane to Nucleo, but found nothing.
So I made it on an experimental card, Each header has 8 bits, and it covers
A0,A1,B0,B1,C0,C1,D0,D1,E0,E1,F0,F1,G0,G1

They are connected just like the Mikroe EasyMX 10 pin headers.

It is many hours work to solder all the wires on ...

Now I found that SB stands for solder bridge
Does that need to be fixed before it works ?
At least SB5, 6, 7 are here

Thanks,
It seems to be in the right direction,
but I can't confirm functionality.

I also don't understand what SB4....SB7 means

I am not sure about the conclusion when using NUCLEO-F746ZG :
Is there a chance to connect the USB directly to a PC and get serial communication
or is a separate USB serial card needed ?

Best regards
BO

Thank you for resolving this so quickly during my lunch
Now it works just great

Hi

Regardning NUCLEO-F746ZG

I just made a test routine to turn all ports on and off
It works great for ports A,B,C,D,E
but there is no reaction on ports F & G

I suspect something with Flowcode, unless I made something wrong,

Bits C8, C9,C14, C15 , D8, D9 are also missing but manual indictates ...

Very helpful, thanks !

Would it be possible to transfer such a big measurement array over UART -USB serial communication
to a PC computer, and make this in the background, allowing the processor to work full speed
collecting the next array ?

I think that the hardware UART also has a hardware ...

Is it possible to read PA0....PA15 into one single variable,

I guess you would call these two bytes UInt

Is it possible to multiply two UInt-s ?

Is it possible to output PB0....PB15 from one single UInt variable ?

Is it possible to store hundreds of such UInt measurements into the large ARM ...

• >Good news. Can I have the Flowcode program for the F469Disco? stefan.erni

This is the simple code to test UART
(Pls observe that it did't work for F469Disco)

but it works for

F429 Disco
F746 Disco

I made a quick and dirty test this way

Just connected different STM32 boards to USB to see if PC discovers a COM port

In these cases a COM was discovered
F429 Disco
F469 Disco
F746 Disco
F767 NUCLEO

Then a flowcode UART loop was made to echo input from PC
These two cards can communicate ...

I still feel confusion about using a UART serial communication over USB to a PC
From the discussion I understood that STM32F469-Discovery will nor support it without external board.


What's about STM32F072 Discovery ?
http://www.st.com/en/evaluation-tools/32f072bdiscovery.html

It says
User ...

This is confusing, but based on this answer stefan.erni was right about the need for an extra board.

Regarding STM32F407VG and how to configure two counters:
This is the STM32F469-Discovery-kit configuration. Can I use the same configuration code ? Or how much is board-specific ?
Deeply grateful ...
