Does anybody know if either the MSP430 or Atmel ATmega AVR parts (or associated JTAG interface widgets/SW) have problems when there are other devices in the JTAG chain? In the past, I've run into buggy JTAG stuff that couldn't tolerate having multiple devices in the JTAG chain. I'm working on a design with both an AVR and an MSP430, and I'd like to have a single JTAG header/chain. Before...

Hello: Our target MCU for an embedded project is MSP430F1612. Our programming team is currenly facing problems caused by trying to upload via BSL programs compiled under IAR 3.42. The BSL upload program (based on the TI BSL program) generates errors when trying to write the first bytes in flash. Then, the prototype board containing the MCU is unusable until older versions of the same ...

Hello, When I toggle a GPIO on my MSP430 processor I have (or at least I think I have :) a clean understanding of what happens. I can relate the frequency of the toggling to the instructions used and the clock speed of the CPU. Nothing strange happens.

Followup to the message I posted the other week about Nokia 2260 LCDs for my Babylonian clock... the electronics are now working. The clock starts at 10:12:10 and ends at 10:13:08 in this video; you get to see most of the digits. It was slightly tricky to fit the 59 digits (at 32 x 22 pixels) into the 2K MSP430; I wound up making a set of sub-
