Hello, I apologize if this question was answered already, I could not find the answer. Perhaps someone can point me to it. I'm using 430F5438 with FTDI's UART > RS232 converter (FT232R). I connect to it using PuTTY client. I do A/D and send it to RS232 through UART: UCA2TXBUF = (char)ADC12MEM0; and instead of a number I see an ASCII character. My question is how to send a number i

HI all In my code I swap the baud rate on my UART dependant on what sensor I am sampling. Usually from 38400 to 9600 and then reset it once sampled. The different sensors are connected to various drivers and then routed through an addressable mux to UART1. The logic is then TTL but the baud rates match the sensor. However, I have noted that the UART sometimes hangs between changes me

Hi There, Is it possible to use the Boot Strap Loader (BSL) interface for device communications as well as programming? Otherwise I have the application note for using a timer to create a UART Cheers Mike

Dear all, I have question about the UART. What is the max baud rate of the USART in MSP430? By the way, I have to communicate with a 16C550 UART (by TI). Is it possible to have a baud rate higher than 115200? Thanks, Marquis

I'v a strange problem when using UART in msp430f149. At lower speeds UART works ok, but at at 115200 speed it sends duplicate characters. Below is a test (after initializing), which should result msp430 sending character "*". insted it sends "**". dint(); TXBUF0 = '*'; while(1); According to debugger (gdb) code executes as inteded. Have ever seen this kind

I'm using an 'F2370 USCI A0 UART and it works fine most of the time, but it regularly stops receiving bytes. If I reset the UART and then un-reset it, it will start to receive again. I'm polling for this condition: (IFG2 & UCA0RXIFG) || (UCA0STAT & (UCFE|UCOE|UCPE|UCBRK|UCRXERR)) And it will it work for 10-20 messages (each message is about 20 bytes long), and then in the middle of...

Hi, I have problem with software UART on F149 uP. Why software? I have big project, and USART1 is used at this time, and it always must be enabled, USART0 i use too, but in SPI mode, and this one must be enabled all time too. I need an second UART (not SPI). Help! Any suggestions ? Cris

I'm new to the MSP430 and I'm trying to familiarize myself with the USART in UART mode. I figured a good start would be to step through some sample code. When I run the MSP430F149 UART Demo Code in the files section of this group, it just hangs at the call to function INITIALISE_BASIC_CLOCK() When I step through this function, the Quadravox AQ430 throws an error at line: BCSCTL

I have spent a lot of time trying to get printf() linked to my low-level output-to-uart routines, and failed at several different methods touted on this and other forums/user groups. I finally arrived at a working solution using sprintf() and MyPuts() (my low-level output routine). Porting a rather large program from IAR (where I had replaced the write() routine to get printf to uart) ...

Have somebody implemented Timer_A UART with parity bit verification or coul= d tell me a tip to do it? I am using MSP430F123 and I need to use two serial interfaces, one is SPI= (using USART I/O) and other is the software implemented Timer_A UART. I ha= ve to read serial data that is provided with odd parity bit, so the Texas e= xample code does not tell how to implement parity bit check. ...

Hello, I am using Timer Module, UART Module and WDT+ of 430F2370 microcontroller. When I try to use different clock sources for these modules, I observed different responses from the system. If I use ACLK for the UART Module and SMCLK for the others (WDT+ and Timer) , the system works properly. However If I switch to SMCLK for UART, the system shows some inconsistencies. Besides, If I...

Hi, i want to use a MultiMediaCard (MMC) with the UART of a MSP430 but i could not find all ports. The MMC has CS, DataIn, Clk and DataOut while the UART has SIM0, STE, SOMI and SCLK. It's clear that i have to take SCLK as Clk but what do i have to connect to CS, DataIn and DataOut? Best regards Rolf Freitag

Hi guys, I need some help. I am implementing a UART where i receive some bits from an RF receiver. The msp430 goes in LPM interrupt and waits until RXBUF receives something. Once it gets something, it will then proceed and follow the code. I would like to implement some sort of time out so that after, say 5 seconds if nothing happens then exit the interrupt and resume with the rest of the c...

There has been some discussion on the UART using the DCO. And a little more which got a little on the unfriendly side so was a bit shy getting into this but what the heck! I have had several problems with the software example provided by TI in the sample code in C. I cannot get the receive section to work and in desperation I just wrote my own bit bang code which does not take advant...
