Choose AD4003 as AD converter, the use of STM32F103 microcontroller

CodePudding user response:

Stm32f103 are not enough, the sampling frequency to 2 MHZ, 16 bits of data, speed of SPI at least 32 megabits per second, in addition to storing data, also need outside enlarge SDRAM, use stm32f429 theoretically possible

CodePudding user response:

There are a great god know

CodePudding user response:

# 1/f, right, want to consider sampling perusal, bandwidth, data storage, signal of 1 MHZ, to perfect acquisition requires more than 5 m sampling speed (in theory at least 2 times the sampling frequency).

CodePudding user response:

Good thank you

CodePudding user response:

The implementation plan can have a great god simply said

Advise LZ to see open source oscilloscope data, taobao has a lot of,

Can refer to their chips and hardware scheme,
