tms320f28035 Study Record VI

The pin of the 1.tms320f28035 must not be able to input a voltage of 5V , and when the pin is pulled up or down, it generates 100uA of current, which is useful in low-power design. Note that the pull-down settings are not easy to come by casually. All pins with output capability, the typical value of the output buffer drive capability is 4mA, which is more than or M3 The pin driver capability of the kernel controller is much weaker.

The 2.tms320f28035 operating voltage is divided into two parts: the 3.3V Flash voltage and the 1.8V core voltage.

3. During the ad sampling process, when the ad sampling port is dangling, the collected values are random values, so no ad port is used to suggest grounding.

4. The main reason for the ADC sampling accuracy is gain error and offset error.

5. From the C Language programming point of view, the library file is divided into static library files and dynamic library files, the static library file is a . lib suffix file. A dynamic library file is a file that is suffixed with a. dll . Whether it is a static library file or a dynamic library file, the function is to encapsulate the functions together and compile them for you or others to call. The advantage is that the compiled library file is not visible source, the confidentiality is very good, but also easy to maintain. Double-clicking on a . libin CCSwill find it garbled.

6. The difference between a static library file and a dynamic library file: The static library is invoked to load directly into memory. The dynamic library is loaded into memory when it is used and freed from memory when it is not in use.
