The problem you are probably running into is power consumption. The board can not supply enough current to run a stepper motor. You are going to need to setup...
The Dragon12+ board contains a driver that will work fine for at least small stepper motors. You can jumper the driver to power it from a separate supply. If...
I have been looking, but I can't seem to find any HCS12 products with more than two undependant SCI ports. Does anyone know of a HSC12 product that does?...
... Check out the HCS12XA family you can get up to 6 SCI's. The 9S12A256 that I use has 3 SCI's but only in the large chip version. In the small chip version...
Hello everybody, it's my first time to use COSMIC to program MC9S12XDP512. I got along well with it. However, i'm a little bit confused on how to write my...
Hi, The vector table contains function addresses, so to implement an interrupt function, you have to create it somewhere with the @interrupt prefix, and you...

Hi everyone, I got a simple question. I need to use port p as general purpose output, I need to take 0V or 5V output from any of pp0-pp5 pins? How can I...
You will have to configure the DDRP (Data Directional Register P) to output. Pending on the HC12 you are using, you will have to set the bits [0-7] of the...
There will be a header file that defines the port registers which you use as unsigned char or in some cases unsigned short variables. What you would write in...
