This patch allows to use Raspberry's GPIOs as RS232 control lines for DDL, if the booster needs so. These changes are a minor part extracted from http://siggsoftware.ch/wordpress/srcpd-mit-mfx-und-anderen-erweiterungen/ ACKdetection This is for ACK detection on a NMRA DCC programming track (using the Raspberry PI's GPIO defined as RI in raspidefs). This is still a bit experimental, because I don't get out ACKs from my locomotive decoders in all cases. These patches are tested only on a Raspberry Pi, but should work for other Linux'es too, as far as not indicated otherwise above. Bernd |
