Which MCU for a given IDE?

YT2095

Problem: I need an MCU with more IO pins and at least as powerfull as the ATmega328p to fill a "gap".

 

Constraints: needs to either be supported or supportable by the Arduino IDE, or MPIDE, or GCbasic, as well as being DIP (through hole) and inexpensive.

 

Background: I can pretty much cover most MCU needs for low end requirements and program then successfully with, ATTiny 85, PIC16c54, PIC16c57 and Atmega 328p. I don`t play the "Fan Boy" game with only sticking to One processor type, I beleive in using the right tool for the job only, I will exclude the use of ARM for the time being as I have No experience with them and can`t afford the time needed for the learning curve.

I`v considered using the 8051 and derivatives but can`t seem to get them to do anything at all (the IDE`s are over complicated too!).

I`m leaning towards the Atmega32 sort or the 644.

 

now to My understanding (and Please correct me if I`m wrong) the atmega 32, is the same as the 8, 16 or 64 etc... with just More or less memory area.

and I`m fairly sure they`re not to be confused with the 1280, or 328 (for obvious reasons) and maybe not even the 644.

 

Tools: I have a USBASP, I can also use an arduino as an ICSP programmer, I have PICKIT2 (but no idea how to use it), I have MPIDE, Arduino IDE, and Great Cow Basic.

 

I`m not after anything Hyper powered over the top baby Monster! of a MCU, just something with more IO pins and at least 32k of mem and just 8 bit.

I already have an Atmega32, and I tried to put the arduino bootloader onto it with the USBASP, and it did "Something", but I`m not entirely sure what, but I could read the code back off it again, so that was a sort of Bonus (all other tries didn`t even do that much!).

 

does Anyone have Working experience of using a 40pin DIP ic, that can be programed with the Arduino IDE?

 

note: I have tried ideas on Chinglish sites to no avail, and also added the profiles to the arduino IDE, but when you read them, it says ****Doesn`t work**** in the header anyway image

 

can someone whom has DONE this themselves before, and got it working, help me out a little?

Thanks image

    I do remember making a programmer which supports most chips including nearly all of the PIC18F parts, I will dig out the details, and there are lots more on the web, plenty of free software too.

     

    If you PM with your address I will send you a small box of my unused samples including some 18F4550, enough to get you started anyway. Anything else you need let me know!

     

    The ICSP signals are the same for all chips, I use 6 pins, Vpp(+5V),GND,PGD(Data),PGC(Clock),PGM(Monitor/Low voltage). I never actually connect PGM to anything but is part of the conector and used in some situations.

     

    There is a range of low cost devices for USB I am looking at using next, PIC18F13K50/PIC18F14K50
