hi

as maybe you have already tried, the latest proteus versions allow you to simulate some stm32F cores, most of the time with the gcc compiler and folders internally generated ...

So i was wondering if some code on stmcube would be simulated in order to verify some i2c stuff i've already tried on pic mcu...

The problem is that the default compiler config doesnt generate the correct elf file.

Code:
So, go to your project properties.
Select the C/C++ build item
Go to settings
In the "Tool Settings" part, set no debug and add at the end of the "Command" line:   -gdwarf-2

After compiling, you will be able to simulate step by step on proteus.



Best regards and sorry if this is not new to you Smiley

There are some hardware Alarm-Receiver Simulators conceived for monitoring this kind of signals like this one :

The price is $575.00 (http://www.microseveninc.com/price8h.htm)

This illustration may help you to understand.

Events are sent from the burglary alarm to this receiver via the telephone line and integrated modem.

The incoming events are handled and sent to the computer via the serial port in a protocol other than the input (automated output), which may vary.

The types of input protocols are several, but what interests me is the output!

At the request of the developers of automatic systems of music light synthesizers, added the function of selecting a frequency for a note number.

As far as I understand in the FFT, in order to determine the frequencies in the range, for example, 20 Hertz, it is necessary to scan a signal with a duration of 1/f, i.e. 0.05 seconds. Those. the lower you want to determine the frequency, the longer the scan period. For normal frequency determination, it is necessary that at least one full frequency period fit into the scan data.
Frequencies that are “higher” than the FFT capability will be superimposed “flipped” onto the main spectrum.

I apologize for my “French” using a translator.

I requested the software a week ago and I'm still waiting for the TI email.

For the time being no response from TI, except for the communication that my request was taken into charge.

Nice job.


I'm wondering how to perform with some precision the following task on two ranges:  (0-100Hz)  and (20k-50kHz)

to set a Fo frequency and amplitude
then output an n number of signal periods accurately (in order to perform a FFT only on that cycles)

I tried to approximate with delays but i still have errors Sad

If you do not receive an answer in a few days you can contact their email (pd@list.ti.com).
I confirm, sometimes it is not so simple to obtain the approuval mainly for US national security issues on key technologies.
Yes, I think so, US national security issues.
so I request here for help.

Yes, you can set 0 Hz. The frequency step can be 0.1 hertz. It is possible to set the maximum available frequency, but MCP601 will miss up to 1 MHz with such a factor. Maximum amplitude up to 3 volts.
