Hi, Am using UART in EVMDM642. It has dual UART. I tried out the example, uarttest.pjt given along with DDK version 1.20. It works fine for UART port A which is a 9-pin port. But when I configure the example for UART port B which is a 10-pin port, the example does not work. Serial communication is not taking place if I use UART port B. Has anyone encou

Hello to all, I m using UART(1650) with the C6711 board, i have written the interface, i give some data to dsp processor from pc through that UART and then my outputs are loop back through same via to pc. This interface is no working, i don't know why? no compiling, errors. Its a run time error. Kindly someone give me a sample program to interface UART with c6711? I

Hi! I'm using DM6437, and finally I can use uart0 with interrupt, but sometimes if I send many messages on com port in short time, uart stops to work completely. I don't see to start interrupt anymore! I assume that it's possible to lost some message on uart, but in this contidion when uart stops to work I have to reset the board to see my application working again.. What can be wrong...

HI all, How can we use McBSP as UART ? I am designing a McBSP to 8051 UART interface. The interface should work on 2 lines (DX,DR) from McBSP and (TXD,RXD) of 8051. any related link will be helpful. regards, Sandeep

First of all thanks for the suggestions. Here are few more observations about the problem. When SDRAM is enabled and refresh is happening, there is no problem with UART until i would't write onto SDRAM. If i read SDRAM. it has no effect. UART works normally. Once I write onto SDRAM, UART gets currupted. If i write less no of bytes, say 10, it

Hi folks I have a c6713 DSK and a UART Daughtercard from Windmill Innovations. I want to Tx the value of a potenciometer, connected to a microcontroller's AD and send this value to the DSK through this UART Daughtercard. I'm using the example program loop_intr from the Chassaing book "Digital Signal Processing and Applications with the C6713 and C6416 DSK", this program is an interrupt-driven u...

Hi, I am using TMS320DM6437 EVM for my project application. I need to do some task on UART (mainly receive routine). My UART module is working fine in polling method at Baud 115200, But I need to use interrupt service based on my application. I have read the SPRA544 Application report and they have given a formula to calculate the vector address as follows Address = ISTP + 32*

Hello, I am a final year student in the UK trying to get the TMS320C6713 DSP to interface with a touchscreen via a UART connection. I am using the DSK from Spectrum Digital and CCS 3.1. I am using SPRA633C document to get the serial port on the DSK to act like a UART. I have connected pin 36, 42 and 44 and DX1, DR1 and GND respectively on the J3 serial port. These pins connect to a MAX232 chip whi...

Hi I am using C6713 and want to interface a UART. Doing so by using McBSP as GPIO. I have taken the code from the TI's SPRA633C document that describes how to use McBSP as a soft UART in GPIO mode. To test the code and verify if I am receiving correctly, I just put the code inside a while(1) loop inside main() as follows voide main(){ ----- ------ while (1){ Ua...

Hello all, I am trying to run the code from spra633 to implement a uart using the first method (mcbsp in serial port configuration) on a dsk6713. The function ProcessTransmitData() seems to work fine and to fill "xmitbuf" correctly, the transmit and receive edma events do occur but the data I get in "recvbuf" is all wrong,the values in "recvbuf" are also random (not 0x0000 or 0xFFFF). I also...
