Hello everybody, probably soon I'll start working with Holtek mcu and a lot of people recommended me to write in assembly code because it seems that the Holtek C- compiler is not optimized for new entry mcus. Could someone suggest a good book to start programming in assembly (Like kernighan ritchie for c?); i know that asm programming is strictly dependent to the architecture so if someone knows where to find any app. notes that clearly teach for holtek mcu i would appreciate it... Best Regards.. B.M
 

There must be a very good reason why you picked Holtek and not Microchip or 8051 based products. These commercial products have lots of development support and a vast amount of example code. Why Holtek?

Basically for Price
 

Holtek are the cheapest micro available on the market so using Holtek for big volume is a good idea. Some of the Holtek micro are very similar to PIC - for example HT82K68 has only one or two minor changes cmpared to PIC assembly. There was a HiTech (Embedded C Compilers and Tools for Software Development: HI-TECH Software) Holtek C compiler - I know this because I used it, but when I go on HiTech site I don't see it.
The build in C compiler in the HOLTEK IDE is also not that bad
 

so it explains why I can't find the Holtek compiler on their site. It's pity - the C compiler for Holtek I used was quite good and efficient. In fact if you can find some copy of this compiler you can adjust it to the new controllers - in most of the cases you need only to change some definition tables - the instruction set is practically the same. Several years ago our company needed such compiler and I contacted and convinced HiTech to start making Holtek compiler, they did the job in few months because it's very similar to PIC compiler.

Writing assembler code is quite unefficient - it takes much longer, the code is unstable and not portable. Is the HOLTEK IDE compiler (payfree) not working for the new parts?
