Therefore RS232 Level Converters (which we talk about in detail later) are used. These are commonly the DS1489 Receiver and the DS1488 as the PC has +12 and -12 volt rails which can be used by these devices. The RS232 Converters will convert the TTL signal into RS232 Logic Levels. Pin No. Name Notes Pin 1

RTC + SPI mit 10ms Auflösung?
zwar eine RTC on board, leider sind aber auf der vorhandenen Hardware die entsprechenden Pins für den 32khz Xtal bereits belegt. (umlöten wegen miniaturisierung und extremen pfusch eher nicht möglich) Jetzt denke ich daran eine externe RTC zu nehmen und damit die RTC des Prozessors zu ersetzen. Tatbestand
schon mal jemand diese RTC verwendet und/oder kann mir helfen?? http://datasheets.maxim-ic.com/en/ds/DS1390-DS1393.pdf Sie scheint das Problem zu lösen nur bei dem Stromverbrauch bin ich mir nicht sicher. die 500µA im Active mode sind mir auf Dauer zu viel. Was bedeutet der standby current? Rennt
