MSP430 Learning - Clock-EEWORLD

Collect

For the MSP430 system, there are three clocks that can be used:

Auxiliary Clock ACLK

Main Clock MCLK——Main System Clock

Subsystem clock SMCLK—— Sub System Clock

There are also some unique clock modules that are owned by some peripherals.

Clock Source

The low frequency LFXT1CLK is usually 32.768KHz;

High frequency XT2CLK

DCOCLK

VLOCLK 12KHz Very-low-power Low-frequency Oscillator

Notice

After PUC, MCLK and SMCLK are taken from DCOCLK, which is about 1.1MHz;

ACLK selects LFXT1CLK, 6pf

VFD electronic clock production

hardware: 1. Royer oscillator circuit outputs one 4V AC and one 25V AC 　　4V directly drives the filament, and the other path provides negative voltage to pt6311 through bridge rectification. 2. The main control uses stm8s003f3 　　The cost is low, and these stm8s are given by the shopkeeper of xbao, which are also very

STM8 HSI clock correction register

STM8 HSI clock correction register (CLK_HSITRIMR) Address offset value: 0x0C Reset value: undefined Position 7:4 Reserved. Always 0. Bit 3:0 HSITRIM : HSI trim value written by software to fine-tune the HSI calibration value Note: On high-density products, only bits 2:0 are available. On medium-density or small-de

STM8 study notes - clock and GPIO

Speaking of the STM8 clock, it is really a tragedy. There is no problem using HSI, and there is no problem switching to HSE, but it doesn't work when switching to LSI. Then I was puzzled, and then I went to the forum for help, and then I learned that there is an option byte (OPTION BYTE). There is such a description in

Discussion on msp430 serial port data transmission and reception

When doing serial communication, I read the book written by Shen Jianhua. I felt that some control words were not listed in the book, and it was easy to forget to write them when writing programs. Unnecessary errors occurred. ME2 IE2 IFG2 (or ME1 IE1 IFG1) The following program uses USART1. You need to find the usage

【MSP430】Capture mode to measure signal duty cycle

The code comes from the 2016 Beidou Cup, which is used to measure air pm2.5. The sensor estimates the particle concentration by measuring the duty cycle of the signal. (1) TimerB settings, working in capture mode: void TimerB_Init(){ TBCCTL0&=~(CCIS1+CCIS0); // Capture source is P4.0, which is CCI0A (also CCI0B)
