MCU simulation SPI interface-deep understanding of SPI bus protocol SPI (serial peripheral interfacer serial peripheral interface) is a synchronous serial communication interface launched by Motorola, the serial connection between the microprocessor compaction controller and the peripheral extended chip has developed into an industrial standard. Currently, various semiconductor companies have released a large number of chips with SPI interfaces with v

Embedded C Strictly distinguishes the case of letters, that is, ABC, ABC, ABC is 3 different names, and assembly language is not case-sensitive, but capital letters generally have special meaning.4. Embedded C does not use line numbers, one line can write multiple statements, but each statement must finally have a ";" As the end, and the assembly language line is a statement.5.

After the basic functions of the system clock generator are established, the scg1, scg0, cpuoff, and oscoff bits of the SR in the CPU are important low-power control bits. As long as any interrupt is responded, the above control bit is pushed into

First, ca+ structureThe msp430g2553 is provided with a comparator comparator_a+ (ca+), as shown in the construction block diagram.Second, input & outputAs shown, the comparator has a co-axial input (v+) and a reverse input (V-). With the software

The analog comparator module 430 was being tuned last night and today, but there is still a problem. I really don't know where the problem is. The user manual clearly shows that the comparator output can be connected to the timer capture. I also
