Info

The Sequential Read function is used to read the contents of the SDRAM and fill them into a file asfollows:1. Specify the starting address in the Address box.2. Specify the number of bytes to be copied into the file in the Length box. If the entire contentsof the SDRAM are to be copied (which involves all 32 Mbytes), then place a checkmark in theEntire Memory box.3. Press Load Memory Content to a File button.4. When the Control Panel responds with the standard Windows dialog box asking for thedestination file, specify the desired file in the usual manner.<strong>User</strong>s can use the similar way to access the EEPROM and EPCS. Please note that users need toerase the EPCS before writing data to it.4.5 Digital AccelerometerThe Control Panel can be used to display the status of the Digital Accelerometer where it measuresthe output of its 3-axis (X, Y, Z). The measurement range and resolution is set to default value ±2g(acceleration of gravity) and 10bit twos complement respectively. Figure 4-6 shows the currentdigital accelerometer status of the DE0-Nano when Accelerometer tab is clicked. The units that aredisplayed are the raw register values converted to decimal. The value in parentheses is thegravitational acceleration values (mg) calculated from the register values according the formula.Table 4-1 shows the rule.Table 4-1 acceleration values convert ruleRegister Value *Formula Result (mg)0 0/511*2 01 1/511*2 3.92 2/511*2 6.817 17/511*2 66.4511 511/511*2 200030
Figure 4-6 Digital Accelerometer status4.6 ADCFrom the Control Panel, users are able to view the eight-channel 12-bit analog-to-digital converterreading. The values shown are the ADC register outputs from all of the eight separate channels. Thevoltage shown is the voltage reading from the separate pins on the extension header. Figure 4-7shows the ADC readings when the ADC tab is chosen.Figure 4-7 ADC Readings31
