High-speed data acquisition configuration program controller based on single-chip microcomputer

Abstract

The invention discloses a single-chip microcomputer-based high-speed data acquisition configuration program controller, which comprises a controller, and the controller comprises an upper computer, a single-chip microcomputer, an EEPROM (Electrically Erasable Programmable Read Only Memory), a clock chip and an ADC (Analog to Digital Converter) chip. According to the high-speed data acquisition configuration program controller based on the single-chip microcomputer, an upper computer and the single-chip microcomputer are used as online debugging tools for acquiring a clock chip and an ADC chip, and debugging work and function operation of the chips are assisted through a visual interface. Meanwhile, a single-chip microcomputer is used as a core control device, a configuration program of the chip can be stored in an EEPROM (Electrically Erasable Programmable Read-Only Memory) which is connected with the single-chip microcomputer and is non-volatile in power failure through an I2C protocol, and after the chip is powered on again, the chip configuration program is automatically read to the single chip from the EEPROM and then is sent to registers of a clock chip and an ADC (Analog to Digital Converter) chip, so that the chip can be and clock configuration and ADC sampling are carried out according to a working method before power failure.

Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a high-speed data acquisition and configuration program controller based on a single chip microcomputer. Background technique [0002] The main working chips of the high-speed data collector are ADC chips and clock chips. The ADC chip completes the conversion of equipment analog signals to digital signals, and outputs the digital signals required by the collector. The clock signal provides a sampling clock for the ADC chip, so that the ADC chip performs analog-to-digital signal conversion according to the set sampling rate. [0003] The working modes and parameters of the ADC chip and the clock chip are generally set through internal registers. At present, the two mainstream chips generally do not integrate a power-down non-volatile device, so there are two main methods for their program configuration. One is the online debugging mode, which configures the chip through...
