특징
- STC15F104W learning board designed for the 51 microcontroller design, on-board common resources, can meet most of the learning needs, detailed description is as follows:
1>. All IO ports are extracted.
2>. The LED of the on-board single-chip MCU control connect to the IO port P3.2, and it can be used for IO port output, PWM wave modulation experiments.
3>. Connecting the on-board the chip switches to the IO port P3.3, and it can be used for IO port input, interrupt and other experiments.
4>. The IO extraoral patch switch and LED do not affect the normal use of IO port.
5>. The on-board TTL level serial port, RXD (connect to P3.0) and TXD (connect to P3.1), which can be used for STC download program / serial communication between upper and lower computer (need timer coordination) and IO port input and output experiments.
6>. Incidental testing procedures. - 1>. Timer module: T0 and T2, T0 work is 16 bits can automatically reset the initial value of the timer counter in the way 0, and it is 8 bits of automatic reset counter in the way 2, in the way 3 is decomposable. The working mode of T2 is fixed on 16 bit automatic reload initial value mode, so it is specially adapted to LED industry. The timer module of this chip can produce higher precision timing time.
2>. Kernel: using Y5 ultra high-speed CPU kernel, 20% faster than regular 1T, see instruction set for details. A total of 111 instructions.
3>. Pin diagram:
The P3.3 is RSTOUT_LOW, power up and reset, the output is low, and the software can be set to low or high level. The pin can be used as the reset circuit of 16 bit or 32 bit single chip microcomputer. P3.4 can output system clock, so it can be used as the clock circuit of 16 bit or 32 bit single chip computer. The chip also has a strong encryption function, which can replace the encryption core.
4>. STC15F104W has no serial port and has relay broadcasting mode. It can simulate I2C, serial port, SPI, and use IO port charging and discharging to measure external voltage to realize AD function.
5>. You can set the input level of the P3.1 through output P3.0 in the download software, which is similar to the relay broadcast mode of the 15 serial port 1.
