Forum Post: RE: TIDM-THDREADING ISOLATED

Hi Ryan. I want to make a three-phase power meter, but that the electronic circuits do not used any of the three phase lines as power supply, is used as a power supply, a DC voltage source independent....

Forum Post: RE: EVM430-F6736 LCD Not Working

I will have someone from the Metering Team comment on this issue. You should not have to make any changes to the provided code. Have you tried downloading the code using the IAR project version?...

Forum Post: RE: MSP430F5510 RGZ/PT code compatibility

I didn't have any software tools (this is a legacy project) but I went ahead and installed the free version of code composer to check. You are right, there is no distinction between the different...

Forum Post: RE: ADC12 (MSP430F5528) 2's complement data format

>By the way, I didn’t understand what you meant by manipulations not needed. Because msp430 is little endian system. Just write ADC data into array of signed integers and you will see that byte...

Forum Post: RE: Delay on UART for MSP430F5438A

Does interrupt occur after configuration alone, without sending any byte? Anyway this is not hardware issue. There's something wrong with code. After 30/40 seconds something else happens which...

Forum Post: RE: Signal measurement

>So the question is all these tasks can be performed by one MCU? Indeed. Depends on sample rate and complexity of signal to generate. Unfortunately you don't specify such data

Forum Post: RE: Signal measurement

i am sending 72 samples via DMA for sine wave to one DAC and that DAC reference driven by second DAC so that amplitude will be controlled

Forum Post: RE: Signal measurement

If you are sending 72 samples every hour then I can process it even using calculator. You see what you missed to tell?

Forum Post: RE: CORTEX_M4_0 - Debug Call Stack stop my program

Why you are checking UART flag in the ADC ISR? while(!(UCA0IFG&UCTXIFG)); If i==buf_size, you are reading ADC result two times during ISR call which is by definition not good idea. Instead of...
