testeur quartz 32khz
here also a photography of the circuit. the SMD transistor should be visible. works fine for 4Mhz, but also no startup from transformer based power supply.
**broken link removed**
from computer USB startup easily.
i will test with E-Block battery (5 to 6 volts) later on...
32768
here the circuit again.
yes i know CMOS gates work for 32768 hz crystal. however, i could also use a PIC directly.
maybe the circuit produces waveforms, but for the LF crystal they are not enough to drive the clock input?
10MOHM*10pf=
10KOHM*10nf=
10OHM*10uf
this should not be...
pic10f icsp
check the configuration word.
it has taken me some hours until i figured out how configure the 10F200 correctly for ICSP. it is actually no problem to program this device.
if the configuration word is not correct, the device can not be programmed via ICSP. Vpp and /MCRL are...
Re: New kit from blueroomelectronics DRAGONFLY Digital Displ
instead of the breadboard, you should support an "expansion" PCB (means to supply parts of the PIC bus).
the breadboard circuit will break off when the robot is driving, at least when the robot is falling down.
also maybe supply...
quartz 32768
i understand what you mean. however, the MOSFET is voltage controlled- all what's driven are internal capacities (and they are in the 10pF range).
i do not understand MOSFET, or quartz oscillator completely, true.
is there are better explanation than the equivalent circuit (L-C)...
32768 hz oscillator circuit
hi this my 1st post here.
topic is a watch crystal oscillator for PIC (microcontroller).
i do not want to use logic gates.
here the circuit (a thread on the microchip forum)
http://forum.microchip.com/tm.aspx?m=271212
there are pictures, and small movies of the...
