answering to your question is not streight forward as should be.
In the project the following microcontroller are involved:
* CONTROLLER: ESP32-WROOM-32. This is a IOT chip designed to be a
flexible wireless SoC (System on Chip). It is a dual core ARM 32 bit
chip
* SUPERVISOR: ATMEGA328P-MU. It is a 8 bit microcontroller extremely
used in several application.
Both microcontroller, as per initial specification, uses Arduino
enviromental. It does not simply mean that we use arduino ide to program
but it means that there is a layer between hardware and firmware that
abstract all microcontroller main functionalities.
Unfortunately is not very easy to track what happens in the arduino
layer. The tools have auto update functionalities but i can right now
make a snapshot of the situation on my computer
ESP32
Following items are involved:
* Arduino IDE: v1.8.12
* Community libraries: SimpliCLI 1.0.8, Wire 1.0.1
* ESP32 toolchain: xtensa-esp32-elf-gcc 1.22.0-80-g6c4433a-5.2.0
The module used is the Adafruit ESP32 Feather but on the board there is
also the possibility to direct soder the ESP32-WROOM-32 in the exact
configuration of the Feather board (so it's identical)
ATMEGA328P-MU
It is configured as Arduino PRO @ 3.3V 8MHz
* Arduino IDE: v1.8.12
* Community libraries: SoftWire (V3 the correct version is included in
the repository), Wire 1.0
* Toolchain: AVR GCC/G++ 7.3.0

Proportional Valve ArduinoCorePP_PWM_hw_v3 firmware
- From Bryerton:
The Italian's use the PWM on DAC1 / A0 / IO25 pin. The API is the ledc API used to control an LED via PWM
- see ArduinoCorePP_PWM_hw_v3.ino
- function setup() attach pin "DAC1" to ledc
ledcSetup(0, 10000, 12); // KO: chan 0, freq in kHz, how many bits of PWM 12 bits = range 0..4095 ledcAttachPin(DAC1, 0); // KO: IO25/A0/DAC1 ledcWrite(0, 0);
- function PressureControlLoop_PRESSIN() see ledcWrite()
if (Pset == 0) {
ledcWrite(0, 0);
} else {
pid_outb = ...; // KO: looks like a digital PID controller
if (pid_outb<0) pid_outb=0; // KO: low limit
pid_outb = pid_outb + 500; // KO: what is this?!?
if (pid_outb>4090) pid_outb=4090; // KO: high limit
ledcWrite(0, pid_outb); // KO: value 500..4090
}

- note1: only members of github "MVM project" can see and access the supervisor repository
- install and build
mkdir -p mvm cd mvm git clone git@github.com:MechanicalVentilatorMilano/supervisor.git cd supervisor/src make AVR_TOOL_PATH=$HOME/arduino-1.8.12/hardware/tools/avr/bin/ # supervisor.elf and supervisor.hex are created
- configure RPi4:
- login as root
- edit /boot/config.txt
- add at the very end of the file: "enable_uart=1"
- beware that this changes the CPU clock speed, see https://www.raspberrypi.org/documentation/configuration/uart.md
- disable agetty login service to /dev/ttyS0:
systemctl mask serial-getty@ttyS0.service systemctl stop serial-getty@ttyS0.service
- to enable user access to /dev/ttyS0, create file /etc/udev/rules.d/01-ttyusb.rules
SUBSYSTEMS=="usb-serial", TAG+="uaccess"
- (to activate this file, run: "udevadm control --reload-rules" and "udevadm trigger --action=add")
- reboot
- observe that /dev/ttyS0 exists and has correct permissions:
root@raspberrypi:/home/pi# ls -l /dev/ttyS0 crw-rw---- 1 root dialout 4, 64 Jun 23 17:01 /dev/ttyS0 root@raspberrypi:/home/pi# ls -l /dev/ttyUSB0 crw-rw----+ 1 root dialout 188, 0 Jun 23 17:01 /dev/ttyUSB0

Firmware to GUI interface
Physical link
USB serial, 115200 bps, usb-serial lines RTS and DSR control reset and programming mode of esp32 processor.
The firmware running inside the ESP32 microcontroller communicates with the outside world using the U0TXD/U0RXD serial interface at 115200 bps, 8 bit, no flow control.
The adafruit HUZZAH32 ESP32 board integrates a serial-to-USB bridge chip and a micro-USB connector. The bridge chip implements a USB-serial communication protocal and provides a way to reset the ESP32 and to cause the ESP32 to enter the flash programming mode by operating the RTS and DSR lines.
Computer running the GUI code should connect to the ESP32 running the MVM firmware using a USB cable (micro-USB to USB-A). On Linux (i.e. RPi4 display unit) GUI should be configured to access /dev/ttyUSB0 with serial port settings listed above.

watchdog
esp32 firmware implements a watchdog timer to check that the GUI is running.
- the watchdog is off at startup
- command "set wdenable 1" enables the watchdog and starts the timer
- command "set watchdog_reset" resets the watchdog timer
- if timer is not reset within 5 sec (hw_rev3, hw_rev4) or 6 sec ("V5"), ALARM_WDOG_PI is fired and bit ERROR_WDOG_PI is set in ALARM_FLAG
- if ALARM_FLAG is non-zero, alarm actions are initialed (see previous section)

On power up:
- boots Raspbian 10 Buster
- starts X11 (in the alt-shift-f7 console)
- starts python3 gui (lightdm -> lxsession -> /home/pi/gui.sh -> /home/pi/work/MVMSoftware/gui/gui/mvm_gui.py)
- if no ESP32 connected, displays an "abort, retry, ignore" dialog
- if ESP32 connected, displays nothing (hung? wrong ESP32 firmware?)
- starts TeamViewer (from systemd)
- user pi is logged in the alt-shift-f1 console (no password) (via systemctl autologin agetty?)
Autologin:
- lightdm: /etc/lightdm/lightdm.conf has this "autologin-user=pi"
- lxsession: /home/pi/.config/lxsession/LXDE-pi/autostart has this: "@/home/pi/gui.sh"
- /etc/systemd/system/autologin@.service has this: "ExecStart=-/sbin/agetty --autologin pi --noclear %I $TERM"
Partitions mounted:
- / (mmcblk p7)
- /boot (mmcblk p6)
Running processes:
- ModemManager (this is a mistake, it will fight over access to /dev/USB0)
- TeamViewer (is this secure, what's the access password?)
- no sshd
- no NetworkManager
Users:
- root, password blank (login disabled)
- pi, password raspberry (default password)
Network:
- eth0 RJ45 - DHCP is enabled, gets an IP address
- wlan0 (radio is on, per rfkill) - configured to connect to 3 wifi networks (2 of them maybe disabled)
- bluetooth (radio is on, per rfkill) - looks to be on, not clear if paired with anything

start MVM GUI on boot
Startup sequence: systemd -> Xserver -> lightdm -> autologin -> ~pi/.xsession -> mvm_gui.perl
- autologin user pi, as root:
- apt-get install lightdm xterm x11-xserver-utils
- edit /etc/lightdm/lightdm.conf change line: autologin-user=pi
- groupadd -r autologin
- gpasswd -a pi autologin
- create ~pi/.xsession with this contents:, as user "pi":
#!/bin/bash #xterm xset s off # don't activate screensaver xset -dpms # disable DPMS (Energy Star) features. xset s noblank # don't blank the video device xset q echo Starting mvm_gui! ./gui/gui/mvm_gui.py skipTests | grep -v "ESP32Serial-DEBUG: get" echo mvm_gui finished!
- to restart GUI, attach USB keyboard and press: ALT-SYSRQ-K (SYSRQ is "print screen")
start MVM GUI through VNC
startup sequence:
- systemd -> /etc/rc.local -> ~pi/startserver.sh -> xvncserver -> Xsession -> ~pi/mvmsession.sh -> mvm_gui
- systemd -> Xserver -> lightdm -> autologin -> .xsession -> startvnc.sh -> xvncviewer
to run mvm_gui through VNC:
- as root:
- apt-get install tigervnc"*" xfonts-100dpi xfonts-75dpi xfonts-scalable
- as user pi:
- create ~pi/mvmsession.sh
#!/bin/bash #xterm xset s off # don't activate screensaver xset -dpms # disable DPMS (Energy Star) features. xset s noblank # don't blank the video device xset q echo Starting mvm_gui! python3 -u $HOME/gui/gui/mvm_gui.py skipTests > $HOME/mvm_gui.log 2>&1 echo mvm_gui finished!
- create ~pi/.xsession
#!/bin/bash #xterm xset s off # don't activate screensaver xset -dpms # disable DPMS (Energy Star) features. xset s noblank # don't blank the video device xset q echo Starting vnc viewer! ./startvnc.sh echo vnc viewer finished!
- create startserver.sh
#!/bin/bash export LD_PRELOAD=/lib/arm-linux-gnueabihf/libgcc_s.so.1 exec tigervncserver -geometry 800x480 -fg --verbose -- ~/mvmsession.sh
- create startvnc.sh
#!/bin/bash exec xtigervncviewer -Shared -SecurityTypes VncAuth,TLSVnc -passwd /home/pi/.vnc/passwd -geometry 800x480 localhost:1
- chmod a+x .xsession mvmsession.sh startvnc.sh startserver.sh
- setup the vncpassword, run vncpasswd, enter password 123456, say yes to create voew-only password, enter password 123456
- as root, add to the beginning of /etc/rc.local, before restart of dhcpd
su - pi -c /home/pi/startserver.sh &
additional adjustments
- create ~pi/.bash_aliases
# .bash_aliases export PS1="`hostname -I`$ " # end
prepare image for VEXOS
- !!! IMPORTANT: remove all private SSH keys from ~pi/.ssh and from ~root/.ssh !!!
