C8051F060 自带高速AD进行数据采集 可达100兆采样率 并切缓存与片外ram 并把采集数据通过串口发送给PC - Data Acquisition example for C8051F060





Descr iption: This example illustrates the use of ADC1 and the DMA to acquire and store

data.　It is intended for use with the C8051F060 target board in the development kit.



// This code measures a signal at the AIN0 input with the 16-bit SAR ADC0.

// The data is sampled at a rate of 100kHz.　ADC output data is transferred to

XDATA memory space using the DMA.

//

// With the EMIF configured for off-chip XRAM access (on the upper ports),

this code moves the ADC data to the C8051F060TB target boards s SRAM device.

// Once data acquisition is complete, the code then prompts the user to press the P3.7

// button on the target board when ready to receive the data via the UART0 serial port.

The TB features an RS-232 transceiver and connector, so the data can be transferred

// to a PC via its serial port.

//

The code is set to acquire up to 32768 samples (for 64kbytes of data).　The SRAM device　　　-

can accommodate up to 128kbytes,
