Hi All, I'm starting a new embedded control project soon, it looks fairly simple so far, read some analog and digital inputs and provide some PRM, digital & serial RS485 outputs. Sampling at about 10Hz should be sufficient. I'm thinking a lower speed 16 or 32bit CPU will do the job. I'd like to use a CPU which: supports source level debugging & fast code download for rapid turn aro...


BGA's are killing my project

Hi everybody- My project uses several BGA parts. We're in the second board rev stage (rev 2). Our board manufacturer doesn't seem to be able to 100% reliably solder those parts down. It makes SW debugging troublesome because one never knows if the SW or the part is misbehaving. We've had 15 boards built and I estimate 20% have BGA problems. I'd like to hear other's experiences with a...

I recently acquired a new laptop, which (of course) has no parallel port. I've been looking into MSP430F169 board from Olimex to use in a prototyping/testing situation for an FPGA. I'm impressed with the MSP430 line, but I'd like to be able to do the device programming and debugging from my usual Linux development environment. Both TI and Olimex make USB-> JTAG programmers/debuggers

I recently purchased a clone Microchip PIC debugger from some Chinese importer http://www.virtualvillage.co.uk/Items/006401-001? (bad idea probably, I know). I set it all up, it programs perfectly and does a POST fine. The problem is with debugging. I hit the 'program' button on MPLAB, the PIC is programmed fine but I get an 'ICD0083' error (cannot enter the debug mode on the chip). I'v...
