Hello everyone!
I am doing Digital Navigation Aids. It consists of a P18F4620 Microcontroller, ISD2560 voice record/playback chip LM4808M amplifier, 5volts and 3.3volts voltage regulators and three switches, the recording switch, the playback switch. First, i should record a...

hi guys,i am using C programming to program the PUSH-BUTTON MODE code.i would like to ask how to re-initialize all the ports?my programming skills are lousy.maybe you be able to explain in simple way..thank you
14 pin ic calculation
to pouchito,
is there any signal coming to the IC?
yes-->at pin 1* of PW0268IC and there is a clock found at pin 16(CLK)
is there a signal coming out of the IC?
yes-->at pin 1* of PW0268IC
*since pin 1 is I_O pin
Do you have this?
this is the datasheet with...
ic - pw0268 with mcu
to pouchito,
therefore the problem is with the srm?
yes
are you getting any output? what is the voltage?
i had gotten the same waveforms as the datasheet shown below:
the Vp-p=9.5Vdc,the Vavg=4.5Vdc with oscilloscope setting 5V/div and 500uSec/div
lm555 buzzer
to pouchito,
your method did work if i use it in another configuration for example if i connect it with the proximity detector,IRPD version 3.when the detector detects it will make the buzzer work.the buzzer works at a range of 4-8 Vdc.however, the problem is my SRM400 module cant...

i am designing a circuit connection using SRM400 module,LM555 timer and a buzzer on the breadboard.however,i do not sure about the value of the resistors used to make the buzzer works..the operation of these devices are:
1. LM555 timer(replacement for MCU) will generate an excitation...
i had modified the subject title of it and posted it again.
Added after 3 minutes:
by the way,i set the units on the settings menu to be thou.i multiple the dimensions with 39.37 and i added 10 because i afraid the hole will be too small.
i am using CADSTAR software to design the impedance matching transformer IFT component
as shown in the link below:
i am not very sure about the dimensioning of the circle pads
this is the link:
if possible,do you have the symbol part and component part of this impedance matching...

hi :D
i am using CADSTAR software to design MOSFET BSS123 component
this is the footprint dimension:
**broken link removed**
i am not very sure the setting of square pads under the assignments on the setting menu.
this is the link:
**broken link removed**
i am looking forward to your replies...
pro wave srm400
thousands of apologies for not being able to explain in details about the SRM400 module.i am not very good at the descriptions.
Recently,i just bought the SRM400 module with the IC,PW0268 from the Pro-wave electronics corporation,http://www.prowave.com.tw .i have a problem with...
any of you had ever use the SRM400 module?
i have a problem with the SRM400 module.i had gotten the desired waveforms when i probed at the desired points/pins .however,i couldnt get the exact distance even though i had tuned the VR1,VR2 and the impedance matching transformer IFT. ti seemed...
hi guys,i would like to ask,
is there anyway to replace the signal generator to pump in the waveform signals into the SRM400 module?i need to design an outdoor device with the use of SRM400 module:cry:
thank you very much:D
it meant that i have to use computer to test it. the problem now is that i would like to generate the excitation pulses without the use of any bulky equipment.i want to build a device using SRM400 to be use outdoor.is it possible?
thank you:D
