PR11 FOR loop count

[yonghui]

if ur fan is consuming low current. u can use L293/ L293D as the driver. u can control 4 fans by using this IC since it has 4 half bridge. u can use BJT oso if ur current is very small, as small as mili amperes.
the PWM code is dependent on the controller u are using. u can refer the datasheet to get the configuration correct. normally u will need to set the CCPCONX and TIMER 2/4/6 configuration register.

changing the pWM duty cycle by loading CCPR register. and PWM frequency is set by using PR register of the timer. u selected.

can someone give me the pwm driver circuit for dc motor? need to control fan speed based on temperature

can you let me know how you modify the code to let the PIC control the fan speed!thank you!

[yonghui]

u can refer to the datasheet for what code to write. check for CCP module in PWM mode.

can you give the sample code??thank you!!

[yonghui]

i dont have sample code.
u can anytime search in google for " PIC PWM C code" mayb u can get some.

If you don study, sample code also you cannot use Confident on that

You can try Cytron's DIY project, they have plenty of DIY project that similar with PR11, I think PR10 should be helpful, you can also try any project which is mobile robot, they should uses PWM to control the motor speed. You can refer to the schematic too.
