EB022 Motor Driver Board

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 ?

Re: ST ARM Hardware Timers - Examples

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 INT Single Pi...

Re: EB071 E-blocks VGA multimedia board under ARM ?

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 the flowc...

Re: EB071 E-blocks VGA multimedia board under ARM ?

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 buffer size ...

Re: EB071 E-blocks VGA multimedia board under ARM ?

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 E-blocks VGA multimedia board under ARM ?

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 used. ...

Re: STM32 ARM UART

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 ?

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

Any ideas how to work efficiently with NUCLEO

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 the...

Does that need to be fixed before it works ?

Re: STM32 ARM UART

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 ?
