Hey, I would rather get rid of the obvious stuff first. If you have fixes to that code, please forward a copy to me! (Yeah, subtract works fine. But...
Hi all, I'm in need of help right now. I want to do some programming on both EEPROM & Flash EEPROM of my controller (MC68HC912B32). However, I haven't been...
Hello, is it possible to use PORT P as normal in/out pin? I have an evaluation-board with a HCS12. A two colour LED is connected to Pins pp0 and pp1. I tried...
Use PTP instead of PORTP. Edward ... From: <folgli@...> To: <68hc12@yahoogroups.com> Sent: Wednesday, December 03, 2008 13:45 Subject: [68HC12] Problems...
Hello, thank you very much! That works....but why? PORTA, PORTK, PORTB...works but PORTP not! Why? Could you explain it perhaps? Thank you very much! Best...
hello, I am trying to control an 4*20 LCD. I hava a problem to display text at the second and fourth line. It is no problem to display text at the first and...
The problem is the odd numbering of the lines: The third line is the 21. char of first line the forth line is the 21. char of second line (numbering chars from...
Yes, I know but the same code runs on a MSP430 perfectly. At the HCS12 it does not run or only the first and third line. It seems that the other lines are not...
I'm new to assembly language and have written an instruction sequence to input a string of characters using the SCI channel 0. The input character string, will...
Hello, I still have a problem. I read the 29 bit ID. I store the data in two variables to display the Identifier on a LCD. I want to disply the ID binary. But...
Hi all, can anybody explain to me what's the relation between BDM and the MCU external clock? How is the data transfer in BDM related to the clock cycle? I'm...
... Bus clock is a half of oscilator clock, or half of PLL clock (provided PLL is available on your chip, enabled and selected). 8MHz is probably the bus clock...
if your code runs on the MSP430 I assume that it is a timing problem during setup of the display. I wrote the code in assembler and did a lot of cycle counting...
Hi i am using MC9s12xdp512 micro controller in my project. I am interface RAM and FPGA to External bus interface of MC9s12xdp512. If Any body is worked on this...
Help is unlikely to be offered until you take the initiative to learn what you can on your own first. Freescale.com has lots of app notes for this family of...
Hello, I am looking for a development board that is as small as possible. It only needs to do one function: transmit a string at a given interval via RS-232...
Hi all, I got a problem with my Flash on my MC68HC912B32 (again.. sigh). I realized that when the S-Record being sent to the MCU, the MCU will only read the...
Thanks Rob for responding my query.. I have written driver for EBI, I am using 16 bit Data bus, my problem i am not getting UDS correctly. Its not toggling for...
Hi Dave Motorola's Gordon Doughman uploaded hc12fp.asm to the files area of this group back on Sept 20th 2002 which is probably the version James Knox refers...
Hello, I have a device that uses 3-wire(TX,RX,GND) communication. It needs 5V and about 75mA power to operate. I'd like to be able to power this thing through...
