Hi all, New to this forum and microcontrollers. I'm a grad. student who's thesis project will involve programming an HC11 and I was wondering if any of you know of a free/cheap compiler for generating code for the HC11 from a C++ program? I realize the code won't be as efficient this way but in this case, efficiency isn't that big an issue. Any help you can offer would be appreciated...

Hi.. Folks comment on how the m68hc11 family is obsolete and shouldn't be used in new designs. Not everyone follows that rule, however. Meade ( www.meade.com ) makes a number of automated telescope families using their "Autostar" embedded computer system. The primary processor is an mc68hc11e1c1n2 It talks via a modified I2C bus to a bunch of distributed PIC chips on subsidiary bo...

However, i dont know how to transfer my program. my compiler just creates a .C file; i dont think its in the right format for my chip(i think the format is .s19, im not sure). do i need to convert the file then dowload the program onto the chip? or can i just download the program as it is? ...

Hi everyone, I'm new to this forum. I'm currently working on a project where I'm using my old MC68HC11EVBU that I got in school way back in 1998. I've been having trouble getting my expanded memory circuit to work. Everytime I try to load my .s19 file I get the message "(rom-6000)." I understand that it's saying that I'm trying to access and invalid address. I tried running the device from...

Hello all, I am using an HC11EVBU2 board with an HC11E9 chip on it, and it also appears to have some external memory on the board as well. I'm trying to find room to write code in where I won't overwrite anything important or have to write to the EPROM (I'm trying to take one step at a time here). In Single Chip Mode I've determined that I can write code in RAM in area 0000-0035 and 0100-
