Dear Pierre,
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
Don't esitate to contact me if you need more information

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

ledcWrite(0, 0);
} else {
pid_outb = ...; // KO: looks like a digital PID controller
if (pid_outb<0) pid_outb=0; // KO: low limit

Prepare
- install arduino: https://daq.triumf.ca/DaqWiki/index.php/ESP32#Arduino_IDE
- install arduino library SimpleCLI (1.0.9)
Build and Flash
- ssh pi@...
- ### git clone git@github.com:NuclearInstruments/MVMFirmwareCpp.git
- git clone git@github.com:dd1dd1/MVMFirmwareCpp.git ### Konstantin's github via ssh
- git clone https://github.com/dd1dd1/MVMFirmwareCpp.git ### Konstantin's github via https
- cd MVMFirmwareCpp
- git checkout ko1 ### get the "V5" firmware
- git checkout v0.1_ko2 ### git the "v0.1" firmware
- ~/arduino-1.8.12/arduino MVMFirmwareCore.ino
- install library SimpleCLI (1.0.9)
- build sketch
- firmware tag "V5" and "v0.1" will fail with error about missing arduino.h. Please use tag "V5_ko1a" or "v0.1_ko2a" instead from Konstantin's github.
- upload sketch into esp32
Connect and Use manually
- use Ardiuno tools -> serial console, set: serial 115200
- or use minicom, set /dev/ttyUSB0, 115200 bps, no flow control
- output on a base esp32 (no baseboard, no hardware, no sensors, etc)

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.

"V5" ALARM_FLAG logic:
"get alarm" returns sys__s->ALARM_FLAG sys_s->ALARM_FLAG bit ERROR_WDOG_PI cleared by command "watchdog_reset", also calls Alarms->ResetWatchdog() AlarmClass::Tick() copies alarm->ALARM_FLAG_FILTERED to _sys_c->ALARM_FLAG alarm->ALARM_FLAG_FILTERED is alarm->ALARM_FLAG without ALARM_FLAG_SNOOZE bits alarm->ALARM_FLAG is set be TriggerAlarm() alarm->ALARM_FLAG bit __ERROR_ALARM_PI is changed by SetAlarmGUI AlarmClass::Tick() called by MVMCode.Tick() if alarm_enable.
"V5" logic of "alarm_enable" (MVMCore data member)
set to false: MVMCore::Init() - FIXME - cannot find who calls it set to true: MVMCore::Tick() if last_alarm_CT > 5000 explanation: alarms are off startup, enabled after 5 seconds of running.
"V5" ALARM_FLAG_SNOOZE logic only in Alarms.cpp
in AlarmClass::Tick(): clear ALARM_FLAG_SNOOZE if ALARM_FLAG_SNOOZE_millis > 120000 in ResetAlarm(): ALARM_FLAG_SNOOZE = ALARM_FLAG, reset ALARM_FLAG_SNOOZE_millis ResetAlarm() called by "set alarm_snooze !29"

alarm actions:
* if ALARM_FLAG contains any alarms: * AlarmSound=true and Sound() drives the buzzer. * isInAlarm=true and AlarmActions(): * blinks the alarm LED with period 250 ms, via HAL->SetAlarmLed() * calls HAL->SetAlarmRele(true), this drives GPIO_RELEALLARM (hw_rev4 A12)
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
