Hello everyone! im here again for the 3rd time to ask for some advice/help. This forum has been so helpful! Recently i've implemented some code on a msp430g2553 to read a 7 segment LED display. My next step is to send that reading to another msp430 or maybe a c2000 micro-controller. End goal: Msp430-1 decodes the LED display and sends 2 digit number to the Msp430-2 then i display the numbers on my monitor. I was looking at the "wire" master write and slave read examples. I have implemented them but they seem not to work, i'm not sure of a couple of things. How do i address SCL and

Halloween comes round, and I can't face all that orange goo everywhere.... so I went cardboard. Rectangular things are easer. What about doing a cube? Oh, yes! And, of course, it needs some good lights: The 5mm round LEDs are RGB, the larger ones are high-brightness white. These are driven with a high pulse current to create the impression of lightning. Code is here: Video:

Hello, Lastly I have whipped up a state machine based protocol for sending small frames using 9-bit address mode. Ft232rl, wrapped up in the MMusb232rl board, doesn't support this mode directly, so I am leaning on changing the parity bit to mark or space to simulate the address bit on the PC side. Everything works as a charm when I single step the program on the PC. Just on a sidenote, this program is coded in Qt using QtSerialPort. However, when I let the program run as it normally would in a production environment, the uC only receives several bytes out of the whole packet. I have observed

Hi. I finaly get VirtualWire working with msp430g2553, but wen I try compiling on msp430g2453 I get: core.a(TimerSerial.cpp.o): In function `TimerSerial__TxIsr': energia-0101E0009/hardware/msp430/cores/msp430/TimerSerial.cpp:213: multiple definition of `__isr_9' VirtualWire/VirtualWire.cpp.o:VirtualWire.cpp:(.text.Timer_A_int+0x0): first defined here collect2: ld returned 1 exit status How to fix library to compile for 2452 ?

Hello, I am using 2553 microchip using Launchpad Rev 1.4 According to https://github.com/energia/Energia/wiki/Hardware I have to cross the jumpers (check the image please) in order to use Serial Communication. How will i do that (without soldering)? Any idea? Thanks,
