Thank you for your replies.
I was not able to figure out exact maximal value, but i found good blog post on this topic.

So I will go with STM32F4 or F7.
One question. There is a lot of submodels of F4 and F7. Would you prefer any of...
shaiko:
USB suits me best.
KlausST:
- Fewer parts to implement
- Easier HW development (I'm not good at this)
- Posibility of cheap dev board with implemened USB data transfer
- Also I know some C - easier code implementation
- No exprience with PLD
Hello,
I need to take 8bit parallel burst signal from external ADC (20 kB per burst, 22,5 MHz). Buffer one burst, send it to PC and wait for another burst. No data processing on MCU side. MCU will know about comming data by trigger on GPIO pin.
Delay between bursts is about 1 second long...
According to paper mentioned above - yes. I will use push-pull topology if the capacitor version won´t be good enough.
Olympus dos not mention the material in datasheet and the support didn´t anwer my question about transducer material.
I will mark this question as solved, because main...
Yes, I know about supertex pulser and their app note. Their pulsers is only for lower voltage and current -> can´t use their product.
I want to use this topology because it´s easier solution. Here
it´s mentioned that it is possible tu use pulser topology with one active element and...
Thank you for you replies!
I want to add some details:
I need only few pulses per second/few seconds. Since the device is only for experimental purpose - it will simulate ophtalmology A-scan on agarose fantom.
Suitable DC/DC design 20V/200V 10 mA can be found on Texas Instruments web. More info...
Hi everybody, I need help with my project.
I want to excite my ultrasound transducer with short square pulses with amplitude around - 185V and width about 440 ns. The transducer resonant frequency is 2,25 MHz with 50 Ω impedance.
What is confusing me:
A) How to select square pulse width...
Hello,
I need help with my project. It´s about A-scan ultrasound, used for eye biometry(more here: http://emedicine.medscape.com/article/1228447-overview). It will serve as a learning tool at my school.
I want to get signal from ADC to PC:
ADC -> buffer -> ATXmega -> USB -> PC
or
ADC ->...
