packagePeripherals

Information

Everything here can be placed in a schematic next to an MCU:

• generic electrical components, wired to a GPx pin like any circuit (LED);
• an educational peripheral driven by a logical message rather than by Modelica.Electrical.Analog (Display, wired to MCU.Display0 through the causal connectors of Interfaces) — see requirements.md, decision "Périphérique d'affichage pédagogique";
• serial devices connected electrically to two pins (Uart*), whose behaviour comes from a command table or a Python script;
• I2C slave peripherals on an open-drain bus (I2c*), whose behaviour comes from a Python script;
• the weighing chain (Weighing), pure Modelica.

The base classes of the serial and I2C devices, which cannot be instantiated, live in Internal.

Contents

Name	Description
LED	LED whose icon lights up according to the current flowing through it (inspired by Arduino.Components.LED, Modelica-Arduino library)
Display	Educational 20x2 display: received text shown on the icon (2-line scrolling) and in the log
Display4x32	Large educational 4x32 text screen: each message received from machine.Display(0) is written under the last line, the screen scrolls once full
Display8x32	Large educational 8x32 text screen: each message received from machine.Display(0) is written under the last line, the screen scrolls once full
UartGenericDevice	External serial device entirely described by its parameters, without creating a dedicated class
UartEchoDevice	Serial echo device: sends back every received byte unchanged
UartTemperatureSensor	Serial temperature sensor: answers AT+TEMP with the measured value, and accepts a setpoint through SET
UartGpsModule	Serial GPS module: spontaneously pushes a position frame, without being asked
UartLcd20x2	Serial 20x2 display: shows on its icon the lines received on its RX pin, with scrolling
I2cGenericDevice	I2C slave peripheral whose whole behaviour comes from a Python script, without creating a dedicated class
I2cEchoDevice	Test I2C peripheral: reads back to the master what it has just written to it
I2cGroveLcdRgb	Grove - LCD RGB Backlight screen (16x2): JHD1313 display controller at 0x3E and PCA9633 backlight driver at 0x62
Weighing	Weighing chain: load cell body, strain gauge bridge, HX711 converter
Analyzers	Measuring instruments: logic analyser probe (decoded frames in a text file, VCD for PulseView)
Radio	Radio link: transparent radio modems connected to the UART of the microcontroller, modulated signal drawn
