74 series integrated circuits can be roughly divided into 6 categories: l 74×× (standard); l 74LS×× (low power Schottky); l 74S×× (Schottky); l 74ALS×× (advanced low power Schottky); l 74AS×× (advance...
I've been using stm32f103 to do some simple applications recently. The chip itself has only two serial ports, and I need four to meet the requirements, so I want to use the ordinary GPIO port to simul...
The ADC conversion module integrated in ADuC812 includes an 8-channel, 12-bit, single-power A/D converter. These A/D converters are composed of conventional successive approximation converters based o...
Almost identical code, sending and receiving are completely correct when debugging under VC, but not when debugging WinCE under EVC. I only changed szBaud.Format("baud=%d parity=%c data=%d stop=%d", b...
Used for SPWM generation in the inverter process. Note that it is not a program generator. It only generates SPWM data. It can be used when the SPWM program uses the table lookup method.
SPWM wave gen...
