For a first test the internal Clock is ok, but it is not stable enough for example when the temperature changes (I've had the problem).

A late reply is better than no reply:

It was the oscillator. With an external crystal everything works fine.

Thanks for the hint. I will make a try with an external oscillator within the next days.

Hi,

I have a project where 2 Motors for blinds have to be synchronized. They both works with a PIC18F46k80 with internal oscillator (16Mhz) and the motors (speeds) are controlled by PWM. For synchr ...

In the past i have made some projects where port pins are directly connected to a connector to the outside and i made some easy steps to face the problems with ESD :

Disable MCLR-Pin in config fuse ...

Like written in another thread :

I always use code like this (for 2 motors with encoder) :

You will need following :

#define CAN_BRG_SYNCH_JUMP_WIDTH 0 //synchronized jump width ( Tq = X+1)
#define CAN_BRG_PROPAGATION_TIME 0 //propagation time select ( Tq = X+1 ...

An easy way should be CAN.

Thanks for telling us what the problem was Sad

After working a little bit with the bootloader and setup I'm really satisfied with it. It works fine and with ease. You can setup all things you need. Only some little bugs in the GUI´s are a little ...

Maybe you have to setup CAN like this :
//--- Setup CAN for 200kbps at 16 MHz (has to be done before loading CAN-Routines) ---
#define CAN_BRG_SYNCH_JUMP_WIDTH 0 // synchronized jump w ...

OK, i got it working.

I had some problems because of my installation of MPLab and of my hardware. But after fixing that i got it working in a short time.

You can code the addres ...

Hi sarodrig,

i was ill last week, but on monday i have ordered a CAN-Adapter and the bootloader (with secure function) it it know it is already sended. On next tuesday i will test it and send a rep ...

I've tested the free version of the DS30Loader (serial) and it worked fine so I think I will give the CAN-Version a try.

Today I've ordered a USC<->CAN-Adapter from IXXAT and when I have expl ...
