Schaltplan Überprüfung und Korrektur

flux

1:04

Verstanden. Ich fasse dein Pin-/Block-Mapping zusammen und gleiche es mit deinem aktuellen Schaltplan ab, inkl. klarer Signalnamen für den PCB-Header.
A) Zentrale MCU: Teensy 4.1
  • Versorgung: 3V3 verteilt an alle Peripherien, I/O ist 3.3 V-kompatibel.
  • SD: BUILTIN_SDCARD, keine externe Buchse nötig.
B) Taster (Start/Stop)
  • Schaltung: U1:33_ → Taster → GND
  • Optional: 100 nF nach GND zum Entprellen. Falls gewünscht, kann ich einen 100nF Capacitor parallel zum Taster ergänzen.
C) IIS3DWB Kit über STEVAL-MKIGIBV2 Sockel, Interface SPI0
  • Teensy Pins zu Netznamen:
    • Pin 10 → ACC_CS
    • Pin 11 → SPI_MOSI
    • Pin 12 → SPI_MISO
    • Pin 13 → SPI_SCK
    • 3V3 → 3V3
    • GND → GND
  • Auf dem PCB: 2×12 Header für STEVAL-MKIGIBV2. Rausführen: 3V3, GND, SPI_SCK, SPI_MOSI (SDI), SPI_MISO (SDO), ACC_CS.
  • Optional/Empfohlen: INT1, INT2 zusätzlich auf den Header legen:
D) OLED SSD1306 (I2C, 0x3C)
  • Teensy Pins zu Netznamen:
    • Pin 18 → I2C_SDA
    • Pin 19 → I2C_SCL
    • 3V3 → 3V3
    • GND → GND
  • PCB 4-Pin-Header (von links nach rechts empfohlen): GND – 3V3 – SDA – SCL
  • Im Schaltplan korrigiert:
    • U3:SDA → SDA, U3:SCL → SCL
    • U3:5V ist derzeit an U1:5V geführt. Soll dieses OLED stattdessen an 3V3? Viele SSD1306-Module akzeptieren 3.3–5 V VCC, aber die I2C-Logik ist 3.3 V. Empfehlung: VCC = 3V3, um Level-Mismatch zu vermeiden. Soll ich [U3:5V] auf 3V3 umklemmen?
  • I2C-Pullups: R1 an SDA→3V3, R2 an SCL→3V3 vorhanden. Bitte Zielwert nennen (4.7 kΩ typ.). Ich kann Eigenschaften setzen.
E) Grove GPS (Air530, Seeed 109020022), UART über Grove-Buchse
  • Pins:
    • GPS_TX (vom Modul) → Teensy RX2 Pin 7 → Net: GPS_RX_T4
    • GPS_RX (zum Modul) → Teensy TX2 Pin 8 → Net: GPS_TX_T4
    • VCC → bevorzugt 3V3
    • GND → GND
  • Grove-Header-Reihenfolge nach Seeed-Standard: GND – VCC – GPS_TX – GPS_RX. Ich kann die Buchse J3 so beschalten und die Netznamen setzen.
F) SD-Karte
  • Keine externe SD-Buchse. Nur Teensy-intern, ok.
Offene Punkte zur Bestätigung:
  1. OLED-Versorgung: VCC auf 3V3 statt 5V umklemmen? Dann verbinde ich [U3:5V] mit 3V3.
  2. I2C-Pullups: Zielwert 4.7 kΩ für R1 und R2 bestätigen?
  3. STEVAL Header: Soll ich INT1/INT2 zusätzlich auf den 2×12 Header legen oder nur intern zum Teensy führen?
  4. Grove GPS VCC: 3V3 bestätigen, und Pin-Reihenfolge GND–VCC–GPS_TX–GPS_RX so festlegen?
Wenn du bestätigst, erstelle ich einen Ausführungsplan und setze die Änderungen direkt im Projekt um.
