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 Description: 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, )
