Линукс конфигурация на платката. Бих постнал и QT5 проекта за emmc, но там ми се върти логото на 3Д на дисплея, а аз обичам да съм в сянка.
Сега се сещам, бая си играхме на 125 мегахерца spi дисплей да завъртим 3Д лого при стартъп. Все пак трябваше да бъде платка за 50 долара изцедено.
1. Format the SD Card with "SD Card Formatter" Application
2. Download the Rasian OS - Raspberry Pi OS with desktop
https://www.raspberrypi.org/software/operating-systems/ #Raspberry Pi OS with desktop
3. Extract the *.iso from the *.zip and upload it to the SD Card with "win32DiskImager" Application
4. After writing open the SD Card from the PC and create a empty file called - ssh.txt on the /boot drive to enable SSH
4. Configure LCD if is awailable:
#Download the LCD Driver:
git clone
https://github.com/waveshare/LCD-show.git cd LCD-show/
chmod +x LCD4C-show
./LCD4C-show
#If orentation is incorrect:
./LCD4C-show 0[90/180/270]
5. Enable USB on CM4
sudo nano /boot/config.txt
dtoverlay=dwc2,dr_mode=host
6. Plug the SD Card connect Mouse, Keyboard and LAN Cable and connect the power

10. Configure MCP2515 CAN Chip in /boot/config.txt write:
# Make TestUtility direcotory in the desktop
sudo mkdir /home/pi/Desktop/TestUtility
sudo mkdir /home/pi/Desktop/Services
sudo nano /boot/config.txt
dtoverlay=mcp2515-can2[0/1/3],oscillator=8000000,interrupt=26
dtoverlay=spi1-1cs
#If the MCP2515 is on SPI1, CS1,2,3.. go to, to download additional dtoverlays:
http://www.industrialberry.com/quad-can ... -canberry/ http://www.industrialberry.com/wp-conte ... verlay.zip #to download the overlays for SPI1.0 - can2 and SPI1.1 - can3
#Extract the archive and copy the two files in /boot/overlays folder
sudo cp mcp2515-can2.dtbo /boot/overlays/mcp2515-can2.dtbo
sudo cp mcp2515-can3.dtbo /boot/overlays/mcp2515-can3.dtbo
#Restart your PI and write
dmesg
#to cmd
#to check are the MCP2515 configured correctly. There should be line like this:
[20.248951] CAN device driver interface
[20.499256] mcp251x spi1.0 can2: MCP2515 successfully initialized.
11. Configure the CAN interface and link:
sudo ip link set can0 up type can bitrate 125000
sudo ifconfig can0 up
sudo ifconfig
# There should be somethink line this:
#can0: flags=193<UP,RUNNING,NOARP> mtu 16
# unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 10 (UNSPEC)
# RX packets 18 bytes 144 (144.0 B)
# RX errors 0 dropped 4 overruns 0 frame 0
# TX packets 11 bytes 82 (82.0 B)
# TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
#To automatically bring up the interface on boot, edit your /etc/network/interfaces file and add the following:
sudo nano /etc/network/interfaces
# Write at the end
auto can0
iface can0 can static
bitrate 125000
# See the interface in FS
ls /sys/bus/spi/devices/spi0.0
#net ...
ls /sys/bus/spi/devices/spi0.0/net/
#can0
ls /sys/bus/spi/devices/spi0.0/net/can0/
#[params]...
# Testing with can utilities
sudo apt-get install can-utils
# Send data
cansend can0 456#43414e2054657374
# Receive
candump can0
12. Test CAN Interface in Python:
import sys, os, can, socket
bus = can.interface.Bus(channel = "can0", bustype = "socketcan_native", bitrate = 50000)
prt = can.Printer()
ntf = can.Notifier(bus, [prt])
# Send
msg = can.Message(arbitration_id = 0x34, data = [1,5,7], is_extended_id = False)
bus.send(msg)
# OR
# Receive
#bus.recv(10.0)
13. Configure the FT Chip used for Modbus(RS485):
#To evade errors make sure that the line: dtoverlay=dwc2,dr_mode=hos is in /boot/config.txt
#Go to:
https://github.com/richardeoin/ftx-prog #and follow instructions
#Configuration is as follows:
CBUS2 - TXDEN
CBUS3 - PWREN
#Steps:
sudo apt-get install build-essential gcc make libftdi-dev
git clone
https://github.com/richardeoin/ftx-prog.git cd ftx-prog/
make
sudo ./ftx_prog --dump
sudo ./ftx_prog --cbus 2 TXDEN
sudo ./ftx_prog --cbus 3 PWREN
sudo ./ftx_prog --dump
14. Test RS485 Interface in Python:
import serial, sys, os
# Openserial port
ser = serial.Serial("/dev/ttyUSB0", 115200, timeout=5)
# readbytes in the serial buffer
n = ser.in_waiting
ser.read(n)
ser.read(ser.in_waiting)
# Send bytes to the serial
wr_str = 'Test123'
ser.write(wr_str.encode())
ser.write(b'Test123')
15. Configure One Wire Interface:
#Instructions:
https://raspberrypi.stackexchange.com/q ... rature-sen i2cdetect -y 1
#Has to have address - 0x18 - DS2482
#Edit config file:
sudo nano /etc/owfs.conf
! server: server = localhost:4304
server: device = /dev/i2c-1
mountpoint = /mnt/1wire
allow_other
http: port = 2121
ftp: port = 2120
server: port = localhost:4304
#Run server:
sudo systemctl enable owserver.service
sudo owfs -C -uall -m /mnt/1wire --allow_other
15. Test OneWire Interface with Pyton:
from pyownet import protocol
owproxy = protocol.proxy(host = 'localhost', port = 4304, flags = protocol.FLG_UNCACHED)
# Find devices
owproxy.dir("")
#['/28.FF857A941605/']
# Find parameters
owproxy.dir("/28.FF857A941605")
#['/28.FF857A941605/address', '/28.FF857A941605/alias', '/28.FF857A941605/crc8', '/28.FF857A941605/errata/', '/28.FF857A941605/family', '/28.FF857A941605/fasttemp', '/28.FF857A941605/id', '/28.FF857A941605/latesttemp', '/28.FF857A941605/locator', '/28.FF857A941605/power', '/28.FF857A941605/r_address', '/28.FF857A941605/r_id', '/28.FF857A941605/r_locator', '/28.FF857A941605/scratchpad', '/28.FF857A941605/temperature', '/28.FF857A941605/temperature10', '/28.FF857A941605/temperature11', '/28.FF857A941605/temperature12', '/28.FF857A941605/temperature9', '/28.FF857A941605/temphigh', '/28.FF857A941605/templow', '/28.FF857A941605/tempres', '/28.FF857A941605/type']

python3
import sys
import time
import datetime
import random
import SDL_DS3231
ds3231 = SDL_DS3231.SDL_DS3231(1, 0x68);
# Write current time to the RTC
ds3231.write_now();
# Read DateTime from the RTC
