Integrated power-on-reset circuit. Fully integrated clock — no external crystal, oscillator, or resonator required. USB bulk transfer mode. Low operating and USB suspend current. Low USB bandwidth consumption. USB 2. Search for:. A PCB layout for the hand-held data logger is shown in Fig. Assemble the circuit on the PCB. After programming, remove it from the programmer and insert it into the PCB.
Your circuit is now ready to use. Insert a pen drive in connector CON2. Temperature sensor LM35 will automatically sense the surrounding temperature. An example is given below to feed inputs through the keyboard. Follow the steps given below to test the circuit. In the example above, data logging starts on October 8, on Sunday at 8 hours 30 minutes.
Actual data logging starts at 8 hours 32 minutes. The process stops at 8 hours 35 minutes. Duration of measurement is within one hour 00 in this case and with updation cycle of every minute.
Remove the pen drive from the board. Recorded Data Results file opened using Excel is shown in Fig. USB data logger operation is roughly divided into two parts: 1 reading and recording sensor data at specific intervals and 2 generating a PDF file when USB connection is established at the end of use. However, standby current consumption will have a dominant effect on battery life, since most of the time the data logger is in a dormant state.
These new MCUs achieve a best-in-class standby current consumption of 0. A reference kit is provided that supports the development of data loggers using the MLQ46x. Company Top. The board files perform board-specific configuration of the drivers provided by the SDK. Remove the definitions for any compilers you do not want to use when rebuilding drivers and libraries.
That is, to omit a compiler, keep the line defining the environment variable, but leave the definition blank. For example:. To build most other libraries, simply run these gmake commands in the directory that contains the makefile for that library. For this release, SysConfig is used in the majority of the examples and is the recommended mechanism for configuring TI Drivers and device-specific components. Please note that SysConfig is not required though. A project can still use the previous board file approach.
This section focuses on configuring TI Drivers, since all devices support TI Drivers using a common configuration framework. Additional components, such as networking stacks, may be configurable using SysConfig for certain targets, and will cause additional source files to be generated. See the device-specific documentation for information about any additional components that SysConfig can be used to configure.
As shown above, SysConfig provides descriptions and links to access reference documentation for the drivers and other modules you can configure. Besides the ease-of-use provided by SysConfig, the tool resolves conflicts on the fly. This ensures that you create a valid pin and TI Driver configuration. In addition, you can view diagrams of the pin configuration as you make changes.
Its output files are stored in a syscfg folder within the build folder. Note that the Generated Sources files are a subset of the build folder syscfg directory.
This was done to make finding and examining the generated source files easier outside of the SysConfig tool. When you save the portableNative. Additionally user may want to add their custom board setup into SysConfig.
It is RTOS independent. Application writers can also provide their own custom Display implementation. This function is very similar to the standard printf function. The configuration for the Display module is in the board. For details about the Display module functionality, refer to the reference documentation. Note: The default printf API is not recommended for use with SDK applications due to the impact on real-time performance and code footprint size.
The System module functionality is unchanged from previous versions and will continue to be supported. TI-RTOS provides a rich set of system-level embedded software, including multi-tasking, power management, device drivers, and instrumentation.
The kernel is designed to be used by applications that require real-time scheduling and synchronization or real-time instrumentation.
