I have code written for a HCS12 Micro and was thinking about porting it over to a HCS12(X). It has interrupts, and it seems that the interrupts are handled differently. Is this true, or if the modules are the same between the 2 chips, will the code just port over and work the same. ------------------------------------

I want to use a Pierce Oscillator (with a 20MHz crystal), but it doesn't work for some reason. Does anyone know where I can get more information or schematics on how to do this together with the HCS12? I'm using HCS12DG256 and the Codewarrior compiler.

Hi All, Does anyone know if there will be a variant of HCS12 with non-multiplexed memory in the future? It seems to me that the only option is to use HC16, but this a little different, does not have so much flash and may be an unpopular choice. I have used this controller and find

While looking around for a way to interface a DP256 processor to SD memory card and USB. I ran across the MC9S12UF32 processor that has hardware interfaces to both. The problem is it does not have a SPI or CAN interface or the AD that I need, so I though I would use both processors. I'm assuming I can somehow communicate between the two processors usi

I wanted to hear opinions on the subject for HCS12 (at least 12 KBytes RAM chips and bigger). - Is somebody using it on HCS12 chips? - How efficient it is (address space utilization and execution speed)? - In general for embedded application (I understand, this depends on

I guess this is a bit of a general question, rather than a specific HCS12 question, but I want to implement it on an HCS12..... I want to be able to 'filter' the value returned from an on-board ADC. When I say 'filter' I think that perhaps 'average' would be a better descripti

Greetings from Technological Arts! I'd like to let everyone in the HCS12(X) community know about several free development tools that have been released recently. This announcement will be especially interesting to those who are not using C or assembler. Several months ago, programmer David Armstrong released a FIG-Forth compiler and IDE for the 9S12XDP (http://mamoru.tbreesama.googlepages.com...
