Forum Post: RE: MSP-ts430pw28A connecting with msp-fet Flash Emulation tool

Hi Michael, To power the MSP-TS430PW28A with the MSP-FET tool, all you need to do is ensure that the jumper JP1 is connecting VCC to int. This will ensure the VCC line powering the microcontroller is...

Forum Post: RE: Initializing UART1 on MSP430F449...

Hello Dennis, I had the chance to visit with Ali today and I watched him execute the example code 'fet440_UART11-38400'(in IAR) without making any changes to it what so ever and the interrupt enable...

Thank you very much for the suggestion. I added the HFXT program below. MCLK is now 48.00 MHz all right. But, situation is almost the same. About 3% slower ADC14 sampling is still happening. What...

Forum Post: RE: MSP432 Factory Reset Causing Error

This issue was handled off-line, but I wanted to close the loop here in case other community members encounter the same issue. In this case, a precision voltage reference was used as the AVCC supply...

Forum Post: RE: Questions for eCOMP operation in LPM3

Hi Ryan, Thanks for follow-up information! I need some clarification to this. 1) What SAC/TIA stand for ? Please clarify what “comparator is different from SAC and TIA” exactly means. 2) The 10uA for...

Forum Post: TM4C129 Log time duration and clock frequecy

Hi, I am using Log_write1 to get the duration between two points of my code (AES encryption) using a TM4C129. The thing is, this time duration is bigger for a 120MHz clock than for a 16MHz clock, which...

Forum Post: RE: I2C MSP430FR6989 Launchpad Communication (PLEASE HELP!)

As it turns out, you were correct. However there were two problems. One was I wired it wrong! Noob problems lol. I lowered the resistance of the I2C resistors to about 7k and that gave me a good clean...

Forum Post: RE: Initializing UART1 on MSP430F449...

Hi Ali, Regarding my first question, is this behavior repeatable for the ME1 register of a USART0 example? URXIE1, GIE, and URXIFG1 must all be set for the USART to service an RX interrupt, another...

Forum Post: RE: FRAM CTPL Library not operating properly after coming out of...

Hi Jim, I'm able to reproduce the same errors you're seeing in IAR. I need to get a better understanding of the issue and will continue to look into this next week. I'll be sure to keep you updated...

Forum Post: RE: MSP430FR2433 low power UART from ACLK?

>UART consumes an additional 4-5µA sending 8 bytes of data. Most probably CPU is main contributor of consumption here - in case you process each byte by CPU using TX interrupts. You could get lower...

Forum Post: RE: Vibration Analysis : In FFT, What is the Input and Output...

Hi Sarath, The answer to your question depends on several things outside of the FFT itself. First, the accelerometer. You mentioned that it's output goes from 0V to 1.8V. The relationship between the...

Forum Post: RE: Initializing UART1 on MSP430F449...

Hi Ryan, No you can set/reset bits on ME1. No Problem. Okay I understand about the interrupt priority if two interrupt occurs at the same time then CPU services the one that has higher priority. Is...

Yeah, my project idles after setup, then waits for a button press to take measurements and then sends them out the TXD/RXD connections to the other side of the Launchpad. It continuously sends data for...

Forum Post: RE: MSP430FR2433 low power UART from ACLK?

Thank you for the answer! In the datasheet I couldn't find out exactly what is UCLK (I hoped that is ACLK). :) I am using wake from RTC and LPM3 mode. The MCU is clocked from an external 32.768 kHz...

Forum Post: RE: MSP430F4152IPMR Programming Issue

Hi Russ, Thanks for the clarifications. To me, it sounds like a change in the firmware is causing this, especially since your hardware hasn't changed. Are your (remote) firmware developers using the...

Ali, Interrupt priority is not related to this issue, especially with using a simple code example. It was simply provided for your knowledge. Regards, Ryan

Forum Post: RE: MSP430FR2433 low power UART from ACLK?

Are you sure that you are correctly entering LPM4? A RTC interrupt should most definitely not be able to wake up the MCU from this power mode. Please provide a simple code example that demonstrates...

Hi Ryan, I did ask you this question since I have the GIE=1, URXIE1=1 but I do not receive an interrupt. Thanks, Ali.

I am sending the UART data with the following function. Wake up is from interrupt after tx finish. After last sent byte system is set to LPM4. for(i = 0; i < txLength; i++) {...
