InstaSPIN™-FOC enabled C2000 Piccolo LaunchPad - Max ADC sampling rate acquire to PC

vijaykumar parmar

InstaSPIN™-FOC enabled C2000 Piccolo LaunchPad 's ADC having sampling rate of 4.6MSPS. I want to acquire all samples to PC and want to process it. If I acquire samples to PC using UART(serial) then it can be maximum 115.2k .How can I transfer all 4.6MSPS to PC?

Hi,

Is this the F28027F launchpad?

You have options like UART, SPI or I2C. As for UART & I2C... you won't be able to achieve high speeds. But with SPI you can but you need a SPI dongle for your PC.

Can you suggest SPI dongle ? Can I use this SPI dongle directly with ADC output instead of using Microcontroller. I want to stream ADC samples to PC.

What do you mean by directly? External ADC?

Microcontroller SPI lines would interface with the above dongle.
