Original question:
Hello,
i have bought drv2700evm-hv500 board,
i conncetd the piezo injector and testing it,
i want to actuate it faster , for example at 150hz frequncy, with 1ms on and rest off.
it is possible to achive with this board, if yes how to do it. i am asking this question becuse while working piezo console i can get max on time as 50ms, i want to reduce it.
thank you.
hello,
i am generating pulses from standard drive section not from wave builder.
in that i am giving on pulse as 50ms and off pulse as 50ms, i cant reduce this time. is this the minimum time drv2700evm-hv500 can handle to get on or off. if not how to reduce this period.
thank you.
Hi Mohammad,
I understand now. It's a limitation of the EVM being driven by the MSP430 rather than a limitation of the device. Those options are using a set minimum of points. If you want something faster you will need to use the waveform builder and create something like below
However, the time between steps is limited to 1ms, but again that's a limitation of the EVM / MSP430 firmware, not the device.
Best regards,
Jeff McPherson
