§01 ESP32转发Zigbee


   利用ESP32构造一个ZIGBEE的网络发送转接 构造了一个通过ESP32转发ZigBee转发模块。下面对于这个模块中相关的很多命令进行测试。

一、继电器命令

  改造其中的 zbcmd 函数,然后重新定义了一组继电器相关的命令。下面命令经过测试都可以正常执行。

#------------------------------------------------------------
ESP32_ZIGBEE_IP     = '192.168.0.114'
ESP32_ZIGBEE_PORT   = 4567

def zbcmd(str):
#    ccloadSerial.write(str + b'\\r')
    strcmd = str + '\\r'
    udpsendstr(ESP32_ZIGBEE_IP,
               ESP32_ZIGBEE_PORT,
               strcmd)

  下面是相应的改造命令:

#------------------------------------------------------------
def V45ON():
    zbcmd('on')

def V45OFF():
    zbcmd('off')

def V45SET(num):
   zbcmd('set %d'%num)

#------------------------------------------------------------
def RClick():
    zbcmd('solenoidrelay pulse 4 50')

def R1Click(t):
    zbcmd('solenoidrelay pulse 2 %d'%t)
    zbcmd('solenoidrelay pulse 2 %d'%t)

def R2Click(t):
    zbcmd('solenoidrelay pulse 8 %d'%t)
    zbcmd('solenoidrelay pulse 8 %d'%t)

def R1ON():
    zbcmd('solenoidrelay on 2')
    zbcmd('solenoidrelay on 2')

def R1OFF():
    zbcmd('solenoidrelay off 2')
    zbcmd('solenoidrelay off 2')

def R2ON():
    zbcmd('solenoidrelay on 8')
    zbcmd('solenoidrelay on 8')

def R2OFF():
    zbcmd('solenoidrelay off 8')
    zbcmd('solenoidrelay off 8')

def OCON(bit123):
    setbit = 0x0

    if (bit123 & 0x1) != 0:
        setbit = setbit | 0x10

    if (bit123 & 0x2) != 0:
        setbit = setbit | 0x20

    if (bit123 & 0x4) != 0:
        setbit = setbit | 0x40

    zbcmd('solenoidrelay on %x'%setbit)

def OCOFF(bit123):
    setbit = 0x0

    if (bit123 & 0x1) != 0:
        setbit = setbit | 0x10

    if (bit123 & 0x2) != 0:
        setbit = setbit | 0x20

    if (bit123 & 0x4) != 0:
        setbit = setbit | 0x40

    zbcmd('solenoidrelay off %x'%setbit)

def RAllON():
    zbcmd('solenoidrelay set 0x7b')

def RALLOFF():
    zbcmd('solenoidrelay set 0x0')

def RSetHV(num):
    zbcmd('solenoidrelay hv %x'%num)

二、滑轨控制命令

1、单轴步进驱动SH-20403

  在 单轴步进驱动模块SH-20403 给出了 SH-20403的驱动参数。

2、双轴滑轨控制

  这个控制器在 DRV8825步进电机驱动控制模块以及双轴平台 进行了描述。

▲ 图1.2.1 Zigbee双轴驱动器

  三组命令:

  • zbcmd(’drvm1 1000’) : 对于顶层移动;
  • zbcmd(’drvm2 1000’):对于底层驱动;
  • zbcmd(’drvorg’) : 两个电机都回复的复位原点。

  当参数大于零时,平台原理步进电机;当参数小于0,平台移动到步进电机;

  • 移动参数: N= 200000,移动距离:6.6mm
from headm import *
from tsmodule.tshardware    import *

zbcmd('drvorg')

3、双轴SH20403

  在 SH-20403AXIS12双轴蓝牙移动框架 给出了这款ZIGBEE移动控制框架的描述。
