Another Logic Analyzer Using Pic And Sourceboost C

Recommended Posts

OK. This one is a bit more intense than my CheapLA version because it uses a couple Xilinx CPLDs and external RAM but the PIC code shows examples of how to use the synchronous SPI interface to talk to the CPLDs and how to change the RS-232 baud rate on the fly when using faster serial cables. Code to control the timer output (to produce a 100Hz to 2.5 MHz clock) is also included.


The project files and schematic can be found here:




P.S. I also updated the cheap logic analyzer to work with 3.3V logic by turning off the on-die pull ups and using external pull downs to ground. There is a link to the cheap version at the location given above.
