Their open ZET6 board, BOOT0 meet low level, BOOT1 dangling (because BOOT1 is used as ordinary IO),

Problems are: LED to PD0 and PD1, flashing light program reset at a time, a certain probability is normal, can sometimes be flashing doubling time, use the punctual atomic mini board (RBT6) flickering lamp program to modify pin, then download directly into the board, at this time will appear afore-mentioned problems, but the use of warships version of the flashing lights routines will be fine, (routine from the punctual atoms)

Don't know it is hardware or software problems, ZE and RC is different?
Please give advice or comments,

Emmm, the secondary vibration of two 20 p capacitance and do not have a thing... Problem solved... Show that auxiliary initial capacitor is very important, with 51 before do not add up resonance capacitance also ok, 32 can't do that

CodePudding user response:

Low power consumption are so small amplitude.
No capacitance is not stable, sometimes to harmonic vibration, or after the unstable directly selected by internal, there is change
