Hi all I'm a newbie in the art of embedded systems develovment. I'm trying to use a MC68HC912B32 for build an portable device and I have some questions. First:...
I operate my 9s12 devices from 5V but I think they will operate from 3.3. Due to the wide voltage variation over discharge I would not power anything directly...
Hi. I just would like to tell you that this Yahoo list targets all what is related to 68HC12 (i.e. HC12, HCS12, HCS12X) silicons and hardware design, ALL...
(1) Some parts such as MC9S12Exxx are 3 to 5V. Others with eeprom are 5V only. You will have to check. (2) Is favourite whatever you do. There are good low...
Hello, We do have a problem with the autostart function of our program. It seems that it would not run standalone. In the T-board manual is specified that...

If you go to freescale.com and click 16 bit processors, then S12&S12X, and then S12X, the list does not show the S12XA family. Does anyone know if this is...

Hi, Rudy. ... The 912B32 will probably work for you at either 3.3V or 5V, but Freescale's specifications are only for 5V. In practice, I routinely run a B32 at...

Hello All There was mention of Freescale not giving enough importance to the ColdFire like not setting up a forum/list for it. Looks like Freescale listened...
please forgive my laziness. i'm using codewarrior IDE 5.5.1272 to develop on mc9s12gc64. i debug using true-time simulator & real-time debugger version 6.1. my...
Hi All Alex, Stephen, Vernon, Andrew... Thanks for your tips. It was very usefull. "Son las palabras, por supuesto, la droga mas poderosa usada por la mente...
Hi. No problem. Do you use the Simulator (Full Chip Simulator) or do you debug real hardware? In the second case, do you use a P&E USB-ML-12 cable (Multilink)?...
Hello, We have a problem with the autostart (stand alone) function of our program. In the T-board manual is specified that there is an autostart function on...

Hi, Here is a brief explanation of the problem and then question. A more detailed explanation is below in case that's helpful to anyone. In reading the serial...
Jay, You are correct...we do listen. Thanks for posting the link to the new Freescale ColdFire forums. Actually, the forums were in planning before all these...
I am still unable to receive data from the host microcontroller via the CAN bus. The below code resides on my mc9s12dp256b chip. The PORTB BIT0 glows...
Hi Ashwin, CAN is not like RS232 where you connect the RX to TX and vice versa and it works. With CAN the transmitting pin must be seen by the receiving pin...

I am sorry, I meant CAN H and CAN L not TX and RX. The motorola board has a CAN controller (MC33388). I am connecting to pins 11 and 12. Is there anything else...
ahhhh, ok, so you have a MC33388 CAN "transceiver". I was just talking to somebody (i think from this list) and they were saying this was a tricky device to...

Where are you actually setting PORTB BIT1 in the code below? Also, the rxdata array is a local var which has no scope beyond the isr func - completely...
... Is the 10k unit pricing not too far from the 1k unit pricing? It's good to see that the pricing appears close to the NE64... Though Freescale needs to...

The PORTB BIT1 is cleared right at the beginning of the CAN receive interrupt routine. I guess the whole code is only good for seeing if the receive interrupt...

Any one out there know more than the pathetic PEMicro's documentation says? We have not been able to find any way to program EEPROM on the 9S12D64 using the...
Wade: The EEPROM requires a seperate algorithm, called "Freescale_MC9S12DJ64_1x16x512_1k_EEPROM.12P". As with all P&E algorithms, this is available as a free...
