Some parts are already more understable to me. You only need to make sure that there's enough memory for the matrix at the place where the pointer points to. Yes, my password is: The current on base is 13mA and whatever i put the resistor value it remain the same Are we supposed to know the schematic for the board you were using?

It is just a question how to choose the RC components.

A lot of chip manufacturers, simply tested their devices with faster clocks and said 'capable of rate up to xxMHz', but don't actually expect this ever to be used How could it benefit designers? So the design thinking 18f45k20.g should be something like: I dont tried the schema on real world.

That is why you are not even getting 1. The few people running the bus at higher speed, simply build the terminators themselves. Some even have both.

Thu Mar 23, 5: 18f45m20.h have to do this for school, it's my first project with microcontrollers and i am a beginner with electronics Yes, for Q3 and Q2, look at the path driving those transistors. Problem is that the half wave has high harmonics from the 'spikes' at the bottom of the waveform. It's honestly so much easier to push other technologies faster, and costs less. Wed Mar 22, 9: This could be the simulator fault?

PIC Posted by bajra. I have a trouble with my program and I don't know why. I cannot test now any of the above ideas, but for the time being I have no other ideas.

To get fast rising edges without using too much current, the circuit has to actively pull the signal 'up' when it starts to rise, and then switch back down to only drawing a low current once the signal is high. Ok, i managed to write the code that gives me the right signal i guess. That datasheets are so hard to get understanded. You're concerned 18f45,20.h the speed of an i2c DAC. Oct 18, 3, Now it points to the desired element.

Read what GopherT wrote, your transistors are getting way too little current to drive them to saturation. See the data sheet for additional information on configuration.
