From: Uwe Hermann Date: Mon, 20 Jan 2014 16:43:01 +0000 (+0100) Subject: uart: Add binaryout/dump support, drop obsolete 'uart_dump' PD. X-Git-Tag: libsigrokdecode-0.3.0~160 X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=0bb7bcf316b528acbe0ef82f4c1e310e756074bc;p=libsigrokdecode.git uart: Add binaryout/dump support, drop obsolete 'uart_dump' PD. The functionality of the preliminary 'uart_dump' PD is now available in the proper 'uart' PD, via the OUTPUT_BINARY mechanism that frontends can use to dump decoded data (in various formats) to a file, or pipe it into other applications, and so on.
