Hi, We are looking to use a simulator for HCS12 family. We are using actually ICC12 for compiling and Dbug-12 for download and some debugging parts. But Dbug-12 doesn't offer the possibility to create breakpoints, execute code, and see meanwhile the variable state, in

Hi all, I have a project I am working on for my senior design and I am hoping to get some advice on a few things, thanks for your time! For my embedded systems class we made a project based around a door security system. One HCS12 had an IR sensor and a wireless transmitter connected, and use PB's to set/enter a password. It then transmitted status bits to a second HCS12 connected to a compu...

Hi All, We are soon going to send some HCS12 modules (9S12D64 and 9S12H256 based) out for field testing. It's easy to e-mail new code to the test sites, but we need a simple method of reprogramming the modules. We effectively have the six pin BDM connector available.

Can anyone let me know if they have some suggestions for the HCS12 prescale, scale, clock, and period, and duty settings for running a standard servo (666Hz+/-130Hz or 1.25-1.75ms). My oscilator is 16MHz, so the bus clock is at 8MHz. It seems that the resolution at these f

Hello, I have two MC9S12DP512 microcontrollers, and I need to interface them. The first mc9s12, has port P set to output, the second mc9s12 has port T set to input, and I want to connect one line on those ports. There are no large amounts of data being sent, as I am just holding the line high or low. My question is, do I need a current limiting resistor in between the two? I have not yet fo...

Hi guys, Is the HCS12 able to control servos? Im using a remote control car which has 2 servos already, but I need to use another servo (or control the existing one) running from the 9S12E128 to control the voltage pot on the cars rmote control transmitter. Im still

Dear group, Freescale is in the process of migrating to new more environmentally friendly products. During this process, many of the HCS12 have appeared to be marked with end of life status. This is due to the transitional time required to get the new Pb free suffix part numbers up and running in the system. During this time, the non environmental frie

Hello Has anyone succeeded in getting Metrowerks Codewarrior 2.0 to debug an hcs12 board with a self-made BDM consisting of a second hcs12 board running d-bug12? (this would sort of be equivalent to Technological Arts' microBDM12SX) The Metrowerks "True Ti

Hello, Does anybody know how can I run application from RAM with metrowerks? I've done a bootloader in C for MC9S12A128 and a program with Builder C++ to download code from PC to HCS12 via RS485. I can download code into block 1, but to download code into block

Dear colleagues, I'd like to use HCS12 in one application, where the user input will be from discrete incremental rotary sensor (in fact, HDD motor with appropriate shaping amplifiers). It gives two logical signals, which are phase shifted (if driven by constant velocity, shift is 90deg.): A: 000011110000111100001111 B: 00111100001111000011110

Hi All I have some code where I put the HCS12 chip to sleep in pseudo-stop mode (i.e PSTP = 1, followed by asm STOP). To the best of my understanding all clocks/oscillators are stopped except for OSCCLK, which causes the real-time interrupt to be generated. The RTI is used to wake up the system. I am working with the NE64 chip. Has anyone worked with putting the device to sleep before?

February 2, 2006 - inDART-One, the new universal In-System Programmer for Freescale Semiconductor HC(S)08 and HCS12(X) microcontrollers, is now available from SofTec Microsystems. inDART-One's fast programming algorithms make it ideal for volume production. The optimized algorithm for MC908GP32 can program the 32KB memory in about 1 second, while the 256KB memory of the MC9S12DP256B ne

My BDM and/or debugger sometimes sets the HCS12 in secure mode. I suspect that it has something to do with the target clock speed, sence the problem has only (yet) occured when I have the HCS12 to run in self clock mode. This do not happen very often, perhaps once per 50 download

Hello, I have a communication between a HCS12 and a Computer. I receive CAN messages with the HCS12. That works fine so far, sending messages, too. Is it possible to get the identifier of an received CAN message? Is it stored in a register or something like that so that I can read out the identifier of the last received CAN message?

Hi all I am using the PEmicro USB HCS08 / HCS12 Multilink unit for programming / debugging. The unit is working good with simple projects, but when I am trying to run the CW debugger using this unit connected to the target board, and the project includes several active interrupts like: SCI + 2x PWM , the device lose synchronization and I can't debug Did anyone knows how to handle it...

I'm using and HCS12 with icc12 compiler. I'm using SCI1 to communicate to a touch screen LCD. This program loads the LCD GUI. When I try loading the program into flash, it doesn't work. When I'm not using flash, the program works fine and GUI is loaded on the screen. When I flash the board, I include the vectors_dp256 file and set the abs_address to 0xef80.
