Hello,I have one chips12, but I can't debug it with P&E USB BDM MULTILINK. I use codewarrior version 5.9, I have installed the latest driver for USB BDM. Every time it shows : the target MCU has no clock or wrong BDM clock speed is used or derivative is secured. So, for P&E USB BDM, the Pin 1: BKGD; Pin2: GND; Pin6: VDD ;Is it correspond to CHIPS12 BDM 6-PIN connector? Thanks a lot. ----...

Hello to All I am designing my own interface for reading and writing to various Freescale MCU's. I've read and written to '908' etc devices for many years with my own interface. Now I would like to make my own project hardware/software to read/write 912D60(A), 912B32 and 9S12DG128 devices via BDM. All the required commands are published in many tech bulletins on the internet but what I...

Hey All, I'm working on a project with a Dragon12 board running codewarrior for the code. i'm trying to get position control of an arm connected to a motor. I manged to get this done, but it kinda oscillates and so my professor suggested i analyse the position values to get a proper proportional control value. i'm trying to use SCI to get output my position error values so i can plot them. ...
Pulse accumulator question - MC9S12XD256MAG

Hi, At work we've been migrating our hardware from the MC68HC11A1CFN3 to MC9S12XD256MAG. Everything is working fine, but we're running into a weird issue with one magnetic sensor that cropped up. What's happening is when the pulse accumulator is setup to get pulses from the sensor, it works, but appears to randomly start losing pulses. Like for example, say I had magnetic data at points x, ...

Hello everyone! I'm a begginer in MCU programming. I was trying to make my MCU get access the flash and write n-bytes on it, for when I reboot my MCU keep this bytes on the flash, for future use. I program in Assembly and my MCU is HCS12X. Can you make a tutorial or a example for me? (explaining how write and read) Thank you very much! ------------------------------------
