Changeset 26 for trunk/firmware/Src/adc.c

Timestamp:

Sep 8, 2025, 6:57:30 PM (7 weeks ago)

Author:

Message:

• Bug in ADC Kalibrierung (STM32 ADC Strom) behoben
• DMA Buffer für ADC 1 und ADC wird vor Überschreibung während bearbeitung geschützt, indem Datenübertragung nur einmalig erfolgt und erst nach Auswertung wieder gestartet wird
• RS485Modbus: Timeout Zeit wird für Baudraten >19200 korrekt berechnet
• Hardware ID geändert
• Separates Register für "Batterie Empty detection mode" auf Adresse 92 angelegt

• trunk/firmware/Src/adc.c (modified) (8 diffs)
