1. Connect the data logger to the PICkit™ 1 Flash Starter Kit J3 connector.
2. Select Acquisition mode as shown below and select the Oscilloscope display, as
3. Click GO to start acquisition. When the acquisition is complete, the data in the
The Samples pull-down list provided in the signal analysis software defines the number
of temperature samples to be taken. In Stand-Alone mode, the samples need to match
the user specified sample size (Table 2-1). The Speed pull-down list does not change
the minimum temperature sampling speed of 60 ms.
FIGURE 2-5:
The oscilloscope display shows the ambient temperature data from the MCP9800. This
display does not support negative numbers. Therefore, the data is offset by 1024. In
addition, the tool does not support 11-bit and 12-bit temperature data.
2.4.2.5
The stripchart tool available on the PICkit™ 1 Flash Starter kit software can be used to
display real time temperature data. This is done by selecting the strip chart tool on the
software and clicking GO.
FIGURE 2-6:
This display does not support negative numbers. Therefore, the data is offset by 1024.
In addition, the tool does not support 11-bit and 12-bit data.
The real-time display does not operator in the Stand-Alone mode.
Note:
shown in Figure 2-5.
EEPROM is transferred to the PC. In Stand-Alone mode, when clicking GO, the
acquisition is bypassed and the data in the EEPROM is transferred to the PC.
LOADING SAMPLES TO THE PC
REAL-TIME DISPLAY ON PC
The progress bar hangs for about 5-6 seconds for 256 temperature sam-
ples. This is due to timing differences between the PC and the PICmicro
microcontroller. The delay increases as the number of samples increase.
The GUI expects acquisition at 100 samples/sec, however, temperature is
acquired at 16 samples/sec.
