Beagleboard Black
Installing libmbus
Upgrade and install dev tools Beaglebone Black/Updating
git clone https://github.com/rscada/libmbus.git
sudo apt install libltdl-dev
./build.sh
./configure
make
sudo make install
Hardware configuration
Display
- Newhaven display 2x20
- Onboard display controller Sitronix ST7036i
Configure display for I2C bus 2
- P9-1 or P9-2 to display VSS (Ground)
- P9-3 or P9-4 to display VDD (3,3 volt)
- P9-16 - GPIO51/EHRPWM1B connect to display RST
- P9-19 - I2C2_SCL connect to display SCL
- P9-20 - I2C2_SDA connect to display SDA
- Capacitor 1 uF between display C1+ and C1-
- Capacitor 1 uF between display VOUT and VSS
- i2C terminator 10 K ohm between display SCL and display VDD
- i2C terminator 10 K ohm between display SDA and display VDD
Backlight
- Anode - A to 5 volt through 2 resistors of 150 ohm in parellel
- Katode - K to GND
mbus
Wires:
- P9-11 (BBB-RX) to MIKROE-3880 M-BUS MASTER CLICK TX
- P9-13 (BBB-TX) to MIKROE-3880 M-BUS MASTER CLICK RX
- P9-1 or P9-2 (BBB-GND) to MIKROE-3880 M-BUS MASTER CLICK GND
- P9-3 or P9-4 (BBB-3V3) to MIKROE-3880 M-BUS MASTER CLICK 3V3
- Connect 36 Volt DC PSU to MIKROE-3880 M-BUS MASTER CLICK 36 Volt +/-
Beaglebone black - debian <= version 9
Configure BBB GPIO for UART - /dev/ttyS4
sudo config-pin P9_11 uart
sudo config-pin P9_13 uart
Beaglebone black - debian > version 9
Insert UART 4 devicetree overlay in /boot/uEnv.txt - fx. use addr0 </source lang=bash> uboot_overlay_addr0=/boot/dtbs/5.10.168-ti-r79/overlays/BB-UART4-00A0.dtbo </source>
Libmbus software
- OLD: Install libmbus - notice: ln -s /usr/local/lib/libmbus.so.0 /usr/lib/
