Download—In Circuit Downloader
The Serial Downloader is a software program that allows the user
to serially download an assembled program (Intel Hex format
file) to the on-chip program FLASH memory via the serial COM1
port on a standard PC. An Application Note (uC004) detailing
this serial download protocol is available from
microconverter.
Debugger/Emulator—In-Circuit Debugger/Emulator
The Debugger/Emulator is a Windows application that allows the
user to debug code execution on silicon using the MicroConverter
UART serial port or via a single pin to provide non intrusive
debug. The debugger provides access to all on-chip peripherals
during a typical debug session, including single-step and mul-
tiple break-point code execution control. C source and assembly
level debug are both possible with the emulator.
ADSIM—Windows Simulator
The Simulator is a Windows application that fully simulates the
MicroConverter functionality including ADC and DAC periph-
erals. The simulator provides an easy-to-use, intuitive, interface to
the MicroConverter functionality and integrates many standard
debug features, including multiple breakpoints, single stepping,
and code execution trace capability. This tool can be used both
as a tutorial guide to the part as well as an efficient way to prove
code functionality before moving to a hardware platform.
