initialization of UART in DM6437

Hi Nethaji,

Regarding to how to initialize UART in DM6437, please refer to section 2.8 of the TMS320DM643x DMP Universal Asynchronous Receiver/Transmitter (UART)

User's Guide SPRU997.

If you do not plan to use the modem control function then either UART should be fine otherwise you must use the UART0.

Also note that UART1 is multiplexed with the TIMER1, HECC and GPIO while UART0 is multiplexed with PWM0 and GPIO.

Hope this helps.

Hello  sir,

Thanks alot for ur reply.

In that initialization procedures, its been given refer device-specific data manual, where do i find this ?

let me clear my position about uart concept. i am zero knowledge about uart concepts.

how to set FIFO for UART ? Pls help me sir !!!!!

Thanks,

Nethaji.D

Hello sir,

Since i am interested to control motors by uart, i ill use uart0 for my application.

i need to transfer audio and video via UART0, how ?

the demo in CCS 3.3, for uart, will be useful for my application.

Hello Nethaji,

Please refer to the Spectrum Digital Web site, they have some example test code that tests the UART in loopback mode.

Hope this helps.

Thanks,

Hello sir,

after successful loading up of data on to the processor, how come i ill transfer the date from PC to processor ?

I get into deeper, after successful feeding of data through CCS, then, via which medium i need to transfer the data ?

kindly help me sir !!!!!!!!!

Thanks,

Nethaji.D

Hi Nethaji,

I don't know if you are using your own custom DM6437 board or a third party type EVM. If you are using the Spectrum Digital DM6437EVM, you would notice there is a DB9 connector (P8) on board. The DM6437 UART0 is connected to this DB9 connector on this board. You would need a DB9 cable to connect it to the PC and then on the PC you would need the Tera Term software to communicate to the DM6437 UART. Refer to the wiki page on Tera Term on how it works.

Hope this helps.

Hello sir,

I want to make DVM to be stand alone.

So that video get captured by DVM and it would get transferred to ARM, by UART.

there is no point of connection with PC.

In this case, what would be the role of TERA TERM ?

Hello Nethaji,

Can you clarify what DVM you refer here is? Who makes it? I am also not 100% clear what you want to achieve. I thought I understand that you want to send some data to the PC via the UART.

Thanks,

Tai

Hello sir,

i will be connecting DVM6437 with ARM processor.

I Will make DVM to be standalone, by means of feeding code via USB emaluator.

Now DVM need to capture the video and its output need to be get transfered to ARM via UART ?

wats the role of tera term in it ?
