Since the TMS320F28x7x series chips have an internal TMU (Trigonometric Math Unit) specifically used to accelerate the execution of commonly used trigonometric functions and arithmetic operations, and
Although there are some 5G transmission projects now, it will take some time for 5G to be fully commercialized. Most 5G module manufacturers are still in the prototype stage, the cost is very high, an
The STM32L452RE is equipped with an RTC timer, which can be used with the OLED screen to realize an electronic clock.
The main program to achieve the effect shown in Figure 1 is:
int main(void)
