Welcome to our site! EDAboard.com is an international Electronics Discussion Forum focused on EDA software, circuits, schematics, books, theory, papers, asic, pld, 8051, DSP, Network, RF, Analog Design, PCB, Service Manuals... and a whole lot more! To participate you need to register. Registration is free. Click here to register now.
Try looking at following tutorial: http://www.embedds.com/8-bit-timercounter0-operation-modes-part1/
It is based on Atmega328, but initialization and modes are pretty same.
Use any ARM Cortex microcontroller based board. Like M3 or M4 family. In my experience STM32F1xx series can be good choice. Try looking around what MCU has more tutorials to start with - will be easier to get in.
Are you trying to connect plain chip to Arduino? If yes, then you don't need level converter. Just connect Arduino Tx and Rx pins to modem Rx and Tx pins and start playing with. But hardly you will get a signal without antenna. Better look for a Arduino Shield that has everything you need.
winarm install
You have to extract WinARM contents to like C:/WinARM folder and then add environment variables to show path where WinARM binaries are C:\WinARM\bin;C:\WinARM\utils\bin
I like this tool and hope it will reach WinAVR level some day.

pic sine wave
I haven't dealt with PIC but in AVR I have used Look-up table with precalculated sine-wave data. Just read and send out through DAC.
With PIC do the same:
Save one period sine-wave to like 256x8 size table in Program memory or another. then using DDS algorithm or simple read one...
avr lcd library
Another WinAVR AVR-GCC 4 bit and 8 bit LCD library which is easy to use and adapt to AVR projects. Some functions are adapted from AVRLib.
Download it here.
More info and example of usage in site.
Not enough information... Is voltage compatible for instance MCU is poered with 5V but RF receiver can accept 3.3 or 4.5V. Other issue may be a mistake on the PCB. And of cource heating may occur because of failure in receiver module.
Why would you want to program ARM with ASM? Strongly recommend to stick with C unless you want to know things :)

Re: neural network
Here is an example os simple neural sensor designed on atmega8:
Use neural sensors to build smart sensor systems using microcontrollers
AVR may work well (Atmega64, Atmega128...)
Yes you can use built in EEPROM for saving constants and modifying them at any time during program flow.
AVR microcontrollers can be programmed using simple ISP, bootloader or JTAG(mega series). These doesn't require additional circuits in the board...
8051 wave generator
You can try:
**broken link removed**
or you can check
**broken link removed** thread.
But the main idea is using DAC (R-2R ladder) and look-up tables in MCU memory.
