EdgeLogix-RPI-1000 User Manual

Step 1: Insert the WM1302 card into Mini-PCIe 2 slot ,connect the antenna. Step 2: Turn on the power of Mini-PCIe 2 $ sudo -i #enable root account privileges $ cd /sys/class/gpio $ echo 22 > export #GPIO22 which is POW_ON signal

$ cd gpio22 $ echo out > direction $ echo 1 > value # turn on the power of Mini PCIe Step 3: Download the test software @ $ git clone https://github.com /Lora-net/sx1302_hal Modify the SX1302_RESET_PIN=6 ( We use GPIO6 as RESET signal) Step 4: $ ./test_loragw_reg -d /dev/spidev0.1

3.7 Signal board

EdgeLogix-RPI-1000 User Manual

3.7.1 Logic architecture
The Logic architecture between CM4 and Signal Board.

There are 6 signals between CM4 and Signal Board.

Signals SPI_MOSI SPI_MISO SPI_SCK SPI_CS# CMD# INT#

Direction Out In Out Out Out In

NOT: All the 6 signals are isolated from main board and signal board.

3.7.2 Update the firmware of signal board

The signal board has a independent MCU itself and a firmware. it also has a built-in update system. Put the firmware.bin in the update folder, the run:
sudo ./update firmware.bin

NOTE 1: To download the latest firmware, Please visit:
https://files.seeedstudio.com/wiki /Edge_Logix/update.zip
NOTE 2: The source code example for programming signal board, Related files :spidev.c, spidev.h, api.c,
api.h and test.c, refer to the source of the source code.

3.8.1 Block Diagram of WDT
The WDT module have three terminals, input, output and LED indicator.
3 V 3

WDI(GPIO4)

WDT

WDO (System RST#)

The WDT is not utilized by default which has no influence on the system. To enable it please download the script here: https://files.seeedstudio.com/wiki /Edge_Logix/WDT.py Reference:

$ python $ import time $ import RPi.GPIO as GPIO $ GPIO.setmode(GPIO.BCM) $ GPIO.setup(4,GPIO.OUT) # WDT FEEED

open the WDT i=10 while(i>0) GPIO.output(4,1) time.sleep(0.001)

GPIO.output(4,0) # then the WDT LED is on

feed the WDT in typical 1 second OR the systom will reset while(1)

GPIO.output(4,1) time.sleep(1) GPIO.output(4,0)

3.8.2 How it works

1. System POWER ON. 2. Delay 200ms. 3. Send WDO a negative pulse with 200ms low level to reset the system. 4. Pull up WDO.
29

EdgeLogix-RPI-1000 User Manual
5. Delay 120 seconds while the indicator flashing (typical 1hz). 6. Turn off the indicator. 7. Wait for 8 pulses at WDI to active WDT module and light the LED. 8. Get Into WDT-FEED mode, at least one pulse should be feed into WDI in at least every 2 seconds, if not, the WDT module should output a negative pulse to reset the system. 9. Goto 2.
3.9 RTC

3.9.1 RTC Chip information

The chip of RTC is PCF8563 from NXP. It is mounted on the system I2C bus, the i2c address should be 0x51.

GPIO2 GPIO3

R16 22R R0402 R17 22R R0402

I2C_SDA I2C_SCL

The OS itself has the driver inside, only we need are some configurations.
3.9.2 Enable RTC
To Enable the RTC you need to: $sudo nano /boot/config.txt
Then add the following line at the bottom of the /boot/config.txt dtoverlay =i2c-rtc,pcf8563
Then reboot the system $sudo reboot
Then use following command to check if the RTC is enabled: $sudo hwclock -rv
The Output should be:

NOTE 1:make sure the i2c-1 driver point is open, and the point is closed default. NOTE 2: the estimated backup time of the RTC is 10 days.
