Hi ESP1,
Thanks for the help. I will try it out on the car, with different values starting with yours to see if i can get close to it ;).
thanks again,

Hi Guys,
i found this link for the snubber circuit:

is this correct more or less ?

Hi ESP1,
Thanks for the reply. The wires for the Lamp are more than 140 cm away as i am planning to replace the car lamps, but on the test they are 40 cm long. Please can you send me a link or formula to calculate the RC snubber on each Fet.
PS. I needed to have electrical isolation from car...
Hi Guys.
recently i am making a SSR controlled by micro.
i build it using a tc4427 and 2 irlr2905 the output from tc4427 is ok without load on the mosfets. when load is connected "light bulb" i have a very oscillating switch off. on switch on its ok.
attached are the schematics and...
Hi All,
i have a pic16f887 which is generating a variable frequency via rs232 input. i am trying to drive an external circuit with it. the external circuit has a different power supply. aka the pic is battery powered the external circuit is connected to the main voltage. i am thinking on using...
Hi guys,
i am tying to make up a program to calculate the PR2 and Timer2 prescaler for a given frequency received by RS232.
i have the rs232 part of getting to read the data, but i am short of finding the right algorithm for the finding of the optimal:
PR2, Timer2 Prescaler.
Can anyone help...
Hi Guys thanka lot for the help.
i searched the net without expecting to find such a very fast support here. i got it working now. the code for main file and ldc driver + the schematic that works for me:
it has a lot of crap as i was trying to get it work so dont blame ME :P.
#include...
hi guys,
i and just trying to get the rs232 data out to the LCD by using the pic16F887. i made a test program for this and i have searched around and came up with this code:
include "D:\Projects\asdfasdsa.h"
//#include <LCD.C>
#define LCD_ENABLE_PIN PIN_B5...
hi all,
i am too loking to make the pic16F887 as a H bridge controller till now i got the example from ccs. but as the H brdge needs a dead time i dont know how to make it with the pic. any suggestion ??? thanks all fro helping.
