Thank you Steve and Doron for the great suggestions. Steve, just placing the function code into the isr netted 1.94 Mhz and combining Doron's suggestion of using Port AD1 vs PortAB resulted in over 2.67 Mhz. Many thanks to you guys for the fine suggestions. I connected the simulator up to the ground station and the telemetry decommed perfectly. Thanks again. When I get a chance I w...

Hi all, I'm using the HCS12 on a PK-HCS12E128 dev board. I'm trying to interface with a D51307N real-time clock chip using the I2C bus and having some issues. Can anyone please point me in the direction of some resources which may help me crack this nut? PS: I looked in the forum for support; the only I2C code -- which was commented in French -- I could find was for the GPIO pins. Th...

We are using CW and a 9sdg128B and need to I/O to a serial port... but have no phsyical serial port on the board. It seems like it should be possible to use Terminal component in the Debugger, but it isn't obvious to me how to do so. The doc set says this component relates to the Abatron BDI... whatever that is. Has anyone any advice on how to do this please, or can it even be done? W...

Hi, everyone! I'm trying to develop a Human-Machine interface using a combo Keypad, graphic lcd Panasonic EDMGRB8KJF (7.8 inch STN colored passive matrix type. The display consists of 640 x 3(RGB) x 480 dots). Unfortunatelly, I've had problems in integrating the LCD on my HC12 EVM board. All else fails: I can't find documentation about LCD type (same at Matsushite Electric Co.!), I c...
