4 Serial

4.1 Enable

/boot/cmdline.txt
 "console=serial0,115200" 

/boot/config.txt
enable_uart=1


4.2 Disable

 Remove  "console=serial0,115200"  from /boot/cmdline.txt


If you want to use the uart as IO device, add "enable_uart=1" into /boot/config.txt


Or you can do it by run "sudo raspi-config" , enter "Advanced Options" and then enter "Serial" ....


4.3 Connections

  • RASP_TXD --- HEX_TX
  • RASP_RXD --- HEX_RX


5 GPIO Control



6 Timezone

$ cat /etc/timezone
Etc/UTC
$ sudo echo "Asia/Shanghai" > /etc/timezone

add following into /etc/profile:

TZ=Asia/Shanghai
export TZ
 $ sudo reboot




7 Static IP

add following into /etc/dhcpcd.conf:

interface eth0
static ip_address=192.168.1.45/24
static routers=192.168.1.1
static domain_name_servers=192.168.1.1




8 ESP8266/ESP8089

Note that the CH_PD signal is connected to the ID_SD signal. This must be mapped as a GPIO (GPIO0) and switched to an output and driven low then switched to an input again before the driver is loaded in order to reset the module. This will be added in the near future in the driver.
