NucleoF103 and ext. crystal
Hello, unfortunately i couldnt find any info about this in the web.
Today i received my F103RB dev-board and everything works as expected.But only with the internal 8MHz clk. After searching the web, i found this manual: http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00105823.pdf
On page 21 it says for ext. crystal: – SB54, SB55 OFF – R35, R37 soldered – C33, C34 soldered with 20pF capacitors – SB16, SB50 OFF
Soldering the crystal and C33/34 is clear for me. But what sould i use for R34/35? I cant find any value....
Anybody knows this??
