Changeset 26 for trunk/fw_g473rct/Core/Src/adc.c

Timestamp:

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
