1 ADC input to 5 DAC outputs


I need software (in C, Simulink, ... anything that goes & is changeable afterwards) to flash on an embedded system (which I haven't purchased/designed yet).

I know a lot of the basics but I'm still a student in electrical engineering.

The system gets 1 analog input to turn the system on or off (it's 12 V) and 1 analog input (varying between 2 - 5 V).

When the system's on it has to output 5 different signals continuously:

4 analog signals and 1 digital signal with a constant duty cycle (it may have an amplitude of 5 V, but 12-13 V would be better).

3 out of the 4 analog signals vary between 0 - 5 V.

The other analog signal is a bit more complex, it has to be the signal of a crankshaft VR sensor (with 60 -2 teeth). It has an amplitude varying between -5 and 5 V, up to -12 to 12 V. It's frequency range varies between about 650-700 Hz up to 4 to 4,5 kHz.

The output signals differ in frequency or value, depending on the given input signal.

I think it would be easiest (and less epensive) if I purchase an already-made PCB with components instead of designing a new one.

The board will be supplied with 12 VDC , but of course it's also possible to supply it with 5 VDC.

If this concept works properly I will make more boards quite similar to this one, but with 7 output signals and the others a bit modified. So it would be best to preserve those extra signals already on my board/microcontroller and I'm also looking for software that's adjustable for me (in terms of delays for the outputs to change and to adjust to output signals).

I also have images and scope data for the input/output signals.

Thank you very much in advance,

Vertel es net iets meer over wat je exact wil. Dit is echt wel meer dan ADC naar DAC want een typische ADC/DAC werkt op pakweg 2 tot 5V. Je hebt dus wat elektronica nodig om +-12V om te turnen naar bv een 0-2V signaal More
