From 46407f7f3e4d2b6e74b3a2e90b38736a792cfc54 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Tue, 10 Jul 2012 22:41:59 -0700 Subject: altos: Force 434.550Mhz by connecting debug gnd and clk (trac #41) Check for pin P2_2 low at startup and set the frequency to 434.550MHz. This value won't get written to flash, so rebooting again will restore the configured frequency.
