PWM-ULN2003A
利用ULN2003A进行驱动,产生PWM波,里边有照片,可供参考,通过本例程了解PWM 的基本原理和使用 (#include <reg52.h>
unsigned char timer1
sbit PWM=P1^2
void system_Ini()
{
TMOD|= 0x11
//PWM
TH1 = 0xfe //11.0592
TL1 = 0x33
TR1 = 1
IE =0x8A
}
main()
{
system_Ini()
while(1)
{ if(timer1>100) timer1=0
if(timer1<30) PWM=0
else PWM=1
}
)

hal timer 32k
可以用指令控制选择信道,设置发射功率,发送数据包(长度可选),接收数据包(接收时延可设),CC2430复位,内部温度传感器读取,定时器时长控制。底层函数基本做好,如果要加入新功能,可自行更改。(You can select the channel with the command control, set the transmit power, transmit data packet (lengths), receive data packets (receiver delay can be set), CC2430 reset, the internal temperature sensor reading, the timer duration control. Basic underlying function well, if you want to add new features to make changes.)
