General information
- external power supply: 24 VDC screw terminals
- regulated down to 5V USB power (+5V_USB) which is
- regulated down to 3.3V (+3V_CPU)
- 4 channels of relay drivers
- 2 screw terminals (CPU_BUZZ/BUZZ and CPU_AUX/AUX1)
- 2 screw terminals (CPU_LED1/AUX2 and CPU_LED2/AUX3)
- connection for "featherwing 2.4in" display
- 7 screw terminals for I2C (I2C 0..6)
- 1 screw terminal for SPI (EXT_SPI_CS0)
- 1 pressure sensor
- 3 sites for microcontroller (only 1 at a time): Adafruit HUZZA32, NanoPi, RaspberryPi
Switches and Jumpers
- JMP3/JMP4 - select +3V_CPU from our regulator or from ESP32 internal regulator
- SW1/SW2/SW3/SW4 - select I2C power +3V_CPU or +5V_USB
- JMP1_DRV1/JMP2_DRV1 (DRV1..DRV4) - select relay driver
Connectors
- power: 24VDC two pin screw terminal
- adafruit huzzah32 socket
- nanopi socket
- raspberry pi 3B socket (40 pin J8)
- SPI: six pin screw teminal
- I2C0..I2C6: four pin screw terminals. i2c switch port order is: SPI, I2C0, I2C1, ... I2C6
- 4x two pin screw terminals: CPU_BUZZ, AUX1, AUX2, AUX3.
System configurations permitted by hardware
- "Italian model": [ MVM-VC + ESP32 ] ---- usb-serial ---- [ RPi3 + GUI ] (remote control) ---- wifi or cat5 or SD/USB flash for data collection
- "one ESP32": [ MVM-VC + ESP32 + small LCD + mini-GUI ] ---- wifi for data collection (no cat5, no SDflash)
- "one Pi": [ MVM-VC + RPi + GUI ] ---- wifi or cat5 or SD/USB flash for data collection
- "two Pi": [ MVM-VC + RPi/NanoPi ] ---- cat5 ---- [ RPi + GUI ] ---- wifi or SD/USB flash for data collection
- "three Pi": [ MVM-VC + RPi/NanoPi (control) ---???--- RPi + GUI (local control) ] ---???--- [ RPi + GUI ] (remote control)
- "2.5 Pi": [ MVM-VC + ESP32 --- usb-serial --- RPi + GUI (local control) ] ---- cat5 ---- [ RPi + GUI ] (remote control)
Notable hardware limitations:
- MVM-VC can be fully operated by ESP32 or RPi or NanoPi (not at the same time)
- ESP32: yes wifi, no cat5 ethernet, no usb, no sd flash (sd flash maybe via adafruit LCD "feather")
- NanoPi: maybe wifi, maybe HDMI/DP connector to drive monitor (NanoPi to be confirmed)
- RPi is the most capable: cat5/rj45 ethernet, wifi, HDMI/DP, USB, SD flash slot.
Abbreviations: MVM-VC - TRIUMF PCB, ESP32 - adafruit HUZZA32/WROOM32/ESP32 icrocontroller, RPi - RaspberryPi, NanoPi - NanoPi, GUI - medium size LCD running the MVM python GUI, mini-GUI - small size LCD running minimal GUI coded in ESP32.

Flow sensor
TBW
Proportional Valve Italian 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
}
- also see valve_control() commented absent code for PWM.

- ### does not work, installs too-old version of yaml 3.13: apt-get install python3-yaml
- pip3 install PyYAML ### version 5.3.1
- ssh pi@rpi
- git clone https://github.com/MechanicalVentilatorMilano/gui.git
- #git clone https://gitlab.triumf.ca/mvmdev/gui.git

Run with python simulator
- cd gui
- ./mvm_gui.py fakeESP32
Run with ESP32 simulator
- load the ardiuno sketch mock/mock.ino into ESP32 (see instructions below)
- ./mvm_gui.py ### default connection is /dev/ttyUSB0 at 115200 bps, change it in default_settings.yaml
MVM-Firmware
Prepare
- install arduino: https://daq.triumf.ca/DaqWiki/index.php/ESP32#Arduino_IDE
Build and Flash
- ssh pi@...
- ### use TRIUMF gitlab branch ko_test instead ### git clone https://github.com/NuclearInstruments/MVMFirmware.git
- git clone https://gitlab.triumf.ca/mvmdev/MVMFirmware.git
- git checkout ko_test
- cd arduino; ./ardiuno
- open .../MVMFirmware/ArduinoCorePP_PWM_hw_v3/ArduinoCorePP_PWM_hw_v3.ino
- install library SimpleCLI (1.0.9), aREST (2.8.0)
- build sketch (there is warnings about TwoWire::requestFrom())
- load sketch
Connect and Use
- 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)
