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...

Hello I am planning to use an hcs12 for a windgenerator controler and was wondering if anyone has had any experience using its PWM output to drive an IGBT. Here the IGBT would be used to control the battery charge current (120 V, max 20 Amp). Could one simply pu

Hello, I am venturing into making a first circuit for a wind turbine controller based around the MC9S12DG256 or MC9S12A256 with a Pierce oscillator. Would anyone be able to give me some feedback on the layout? In the device guide, Motorola says the tracks to the oscill

Hello All I see that there is a gcc12 port for the HC(S)12 mcus, I would like to use a linux workstation for some hobby project development. Quick question:- 1.) does the gdb connect to the serial monitor on the chips? 2.) is it possible to do source level debug

I used before HC12 (60 and 128) and it's msCAN-module which worked fine. Now I have tried to use MC9S12D64 microcontroller's msCAN-module and I have got it to send messages (checked with oscilloscope) but there is something wrong in the sending because my monitor program (national

Hi All I just recently started with HCS12 and this weekend I decided to use it on a little project. I need to generate a 250uS pulse every 250mS. So I modified the example program RTI that came with the Kit, I changed the RTI prescale and modify the rest of the program to toggle PORTB bit 0. the program worked great... Then as I was going to add

Hi, I am looking for a CAN and/or Serial bootloader for HCS12 (MC9S12DP256) and I've found several options: 1. Serial (AN2153 and AN2153SW) 2. LRAE (AN2546) and AN2720/D (Flash routines) 3. BootRom.zip (on this group, by lenux22) - Can anybody tell me what is the easiest one to start with? - I have tried to compile AN2153SW

I have just started learning microcontrollers. Can someone help me to provide the program (C) of the following steps: 1. Configure and enable the ATD (i.e. Analog to Digital) subsystem of the Motorola HCS12 (ATDCTL2, 3, 5). 10 Bit accuracy should be used. 2. Trigger conversions on 4 channels of the ATD. 3. Wait for the 4 co

I have calculated the BR value and programmed the SCI for different rates without problem, but I haven't found a maximum rate specified. I sort of assumed it was limited by the BR register, but I have not been able to get 115.2k to work. Has anyone else? Does anyone know the max rat

I'm writing some FLASH programming code, and now I have reached final step of securing the microcontroller. Unsecured microcontroller has lower bits of byte at 0xff0e equal to 0bxxxxxx10. Now if I want to secure it, I have to write something different there. Because LSB is already zeroed, there are two possibilities: one is to first erase it and then program

Hi all, I just signed up for this group.. I needed to ask someone for some help.. I am working on a project, and a part of it requires me to take information that is being sent in from a GPS device and parse the string to extract the latitude and longitude coordinates and send it serially to a laptop connected via the second serial port.. The GPS device unfortunately can't be controlled to send...
