LoLA is a very low-cost 8-bit logic-analyzer based on the Atmel AT90S1200 microcontroller. Update v0.23: BUG fixed: Timing parameters were saved in DAT-Files but not updated when file was reloaded. Sorry! In timing-mode data is recorded by internal clockrates from 2us to 16ms per sample or by an external clock on rising or falling edge. The triggercondition can be specified by an internal triggerword (bits set to high, low or don't care) or by an external trigger on rising or falling edge. In state-mode every change on the input-channels is stored in memory. Data can be captured nearly every 1,2us. This means, a signal about 400kHz (with 50% duty-cycle) is recorded without problems. The LoLA.EXE program commands the controller and shows the recorded data in a timing-diagram. The analyzer can handle the recorded data from an I2C- Bus communication or a LC-Display in 4-bit-mode. Sample-Datafiles: I2CTEST.DAT is an I2C-communication recorded in timing- mode. SAA10***D.DAT is an I2C-communication recorded in state- mode. Both can be handled by the I2C-Analyzer. LCD.DAT is the captured data (state-mode) from a LC-Display, it can also be analyzed. WZERO.DAT is a testpattern, generated by the 90S1200- controller. The Picture-Files: These files show screenshots from LoLA.EXE.
