PIC16F1454 used as inexpensive ARM debugger

Saturday, January 25th, 2014

Peter Lawrence has been working on using a PIC as a CMSIS-DAP ARM debugger. I wanted to see what was feasible in the way of a very-low-cost ARM board. OK, that doesn't sound original, but stick with me. The solutions that I've seen (Tweeny, McHck, mbed, etc.) are limited to...

DSJTAG – USB JTAG debugger and programmer for both Xilinx and Altera IDEs

Monday, December 26th, 2011

Seeed has a cheap JTAG programmer/debugger for both major FPGA/CPLD brands. It emulates both the Xilinx Platform USB Cable and Altera USB blaster JTAG programmers with a flip of a switch. As a Xilinx Platform USB Cable it is supported by the manufacture's iMPACT, ISE, Chipscope and EDK software bundles....

Bus Blaster v2 testing

Tuesday, January 4th, 2011

We've just completed verification of the Bus Blaster v2 JTAG debugger. V2 is much more flexible than v1, and uses a programmable logic chip (CPLD) for the buffer. The logic chips in v1 were expensive to source and place, but v2 uses a $1 CPLD with a bunch less pins...

Improving the MSP430 debugger

Thursday, December 2nd, 2010

Travis Goodspeed studied the MSP430 FET debugger, and redesigned it with a bunch of improvements: A FET is any Flash Emulation Tool containing an MSP430F1612, including the FET UIF and EZ430 debuggers. I am happy to announce my own variant of the MSP430 FET debugger. My variant is compatible with...
