When verifying the serial port function according to the following example program, the data monitored by the serial port is all 00 00. What is the reason? void main() { uint8_t str[]="mtrliya"; GPIO_
External structure of the microcontroller:1. DIP40 dual in-line socket;2. P0, P1, P2, P3 four 8-bit quasi-bidirectional I/O pins; (When used as I/O input, a high level must be output first)3. Power su
We have also made many innovations on the i.MX8M Mini development platform. One important point is that the ITOP-I.MX8M Mini core board power management adopts the PMIC power management chip PCA9450A
The sampling rate is above 1M, but the frequency range of the signal is only 37k-43k. FFT will calculate a lot of zeros. Is there any way to calculate the spectrum in a specified range? The current ha
