Hi, Can anyone give me some suggestion about the above microcontroller? I have developed a application program by using the CME-11E9-EVBU development board, where the starting address and reset vector both at $E000, RAM at $0200, STACK at $0FFF, and EEPROM (for data storage

Hi, I am working with a Microcore11 board with an HC11 E0 chip. I have been unsuccessfully attempting to reprogram the EEPROM on the board, using both MicroLoad and JBug. I have tried the suggestions on the FAQ on the Microcore website www.technologicalarts.com ,but no luck.

Q) You are required to read the 8 switches and control the LEDs using port A in real time. You need to control the LEDs in at least 3 different ways of circulation in real time, which should be selected by pushing different pushbuttons. You need to consider hardware connection yo

Hi, I'm quite new to the HC11 architecture. I've been able to install the GNU C compiler and got it working. But I wanted to know how to configure the system to use it in expanded mode. I want to load the PROM and use it with the 68HC11F1. I know that the MODA, MODB pins should be

I would like to use the XIRQ interrupt as a power loss detection. I have it connected to Vdd thru an external pull-up resistor. So whenever the power about to go out, I need to update 6 bytes of the Internal EEPROM. Appearantly, it is not working. The XIRQ does not detect when th

Hi, Can anyone give me some guidelines on Designing a Graphic User Interface for 68hc11e9 microcontroller? I had developed a program on mc68hc11e9 development board. The program will do different tasks depending on "key" input by user. It's means that the program will
