Subject: altos: Use alt_t value to hold displayed height in micropeak
X-Git-Tag: micropeak-build-2012-12-09
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=c233ef67f42c14cb1d0e0542a9523b279f826af5

altos: Use alt_t value to hold displayed height in micropeak

Heights are 32 bits (to get .1 meter resolution) in micropeak; make
sure we have enough bits while blinking out the computed value.
