I am using Analog Devices MicroConverters (ADuC8xx) with 8052 cores. These chips have a "single pin emulator' capability.
We bought an inexpensive emulator from However, it only works with the free 'brain dead' compiler or with Keil.
So, we have been plodding along with SDCC and the old 'printf' debugging approach.
  1. Are there any emulators out that that work with SDCC for in circuit debugging?
Thanks in advance,
