Hello Tom I try to put your code in my program for a slave I2C pic. But i get never a interrupt. Do you know what could be the problem? Code if interrupt has occured: void interrupt(){ if (PIR1.SSPIF = 1){ I believe this should be changed to void interrupt(){ if (PIR1.SSPIF == 1){ Give it a try and...

thanx. but i send data from master do not read on slave portB. master PortC.F3 to Slave PortC.F4 & M PortC.F4 To S PortC.F3 is right shematic. I'm not sure if you are asking a question here or trying to state something but I'll try to explain a little bit more. You send serial data from the Master ...

Hi all, here is some simple code for Master/Slave I2C projects. I can't take all of the credit for writing this. I used mB and mP code/methods that I found on the forum and translated it into this. Feel free to comment, but I might not be quick to respond because I only get on here about 1-2 times a...

It sounds like you are on the right track. You might want to consider gating the SCL line instead of SDO. If you only gate SDO and still send out SCL, you're basically doing the equivilent of sending all "1's" or all "0's" (depending if you pull up or down SDO). Just a thought.

I know it's been a while since you posted this, but I just found your post and thought this information might help you if you haven't figured it out yet. Somthing that you might want to consider is that for 5000 RPM and a 4 cylinder engine the frequency you will see from the ignition coil or Engine ...

Joe,
It's not just the 16F88. The 16F690 gets the same errors, and I'm assuming there are others as well.
