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...
First download IAR yourself, I use 8.30 and then open the file [img=110,0]https://bbs.eeworld.com.cn/forum.php?mod=image&aid=146589&size=300x300&key=220961f30369fd97&nocache=yes&type=fixnone[/img] to ...
Chip: STM32F103C8T6 Application Pin: Output: PA0, PA1 TIM2 CH2 channel To achieve 50HZ (20ms) adjustable PWM output on the PA1 pin, set the system TIMx_CNT=8MHZ=8000 000HZ, set TIMx_PSC=800-1, then T...[Details]

Similar to the development trend of photovoltaic modules, photovoltaic inverters are also one of the examples of China's successful localization of manufacturing and leading the global market and tech...[Details]
The analog watchdog of the ADC is used to check if the voltage is out of bounds. It has two upper and lower bounds, which can be set in the registers ADC_HTR and ADC_LTR respectively. The library fun...[Details]
The role of the watchdog: Since the operation of the microcontroller is often interfered by the external electromagnetic field, the program may run away and fall into an infinite loop. The normal ope...[Details]
Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]
A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]
The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]
