The monostable trigger receives the 40ms pulse wave output from the P1.3 port of the S430F1101. After the voltage boost and pulse width control of the trigger, it outputs a square wave with a constant...
As the title says, I recently used TI motor driver demo board DRV8301 to develop motor driver, which requires SPI communication. After the software writes the SPIA program, the output signal TX needs ...
This is a simple taskwhile(1) { _tv.tv_sec = 0; _tv.tv_usec = time; /* If using 10000 us, then the system hang will not occur. */res = select(0, NULL, NULL, NULL, _tv); if (res0errno != EINTRerrno != ...
Today I saw a blog post that says: Assuming the system clock is 72Mhz, TIM1 is derived from PCLK2 (72MHz), and TIM2-7 is derived from PCLK1. The key is to set the clock pre-division number and the val...
There is no serial port protocol between the upper and lower computers. When one side is ready to receive, the other side can send. Now the question is how can the receiver know that the data stream h...
