NEED AN ADVICE FOR NEW PROJECT

[AntoR]

Hello everyone.

I have to create an arbitrary waveform generator via DAC starting from a lookup array of 32 elements at least with 10bit resolution. However, I must be able to reach frequencies of around 300Khz. I wonder, which evaluation board can I consider?
Thank you in advance

The DAC on the STM32's is generally limited to around 1 Msps, you can drive both from a pattern buffer via DMA, and paced by TIM.

Pins PA4 / PA5 in modes cases, as I recall, check boards with Arduino Shield sockets that escape the DAC pins.

Other than that, perhaps SAI interface to a CODEC.

Exist a evaluation board with 5Msps DAC capable?

If not, you can suggest alternative for realyze this prototype?

 

Thanks

Why do you specifically have to do it it via DAC ?

There are chips available to do this kind of thing; eg,

Try also searching for "DDS"; eg,

I need a solution to generate any type of arbitrary signal and not just sinusoidal, triangular and square, which is why the reason for a high-performance solution via a DAC
Is there something for this?
