Maximum support Baudrate of SCI module in F2812

Started by msr_...@yahoo.co.in May 31, 2008
Hi All,,

I am running my application at 128Mhz system clock out rate on Flash.
Is it SCI module support for 5 Mbps baudrate for communicating another SCI module in F2812.?

One more thing is can i have the maximum baudrate of SCI module supports,

Thanks in advance

Regarsd,

Srinu!!!

Theoritically, based on the what the configuration registers allow for
Low Speed clock and SCI baudrate calculation, it should be possible.
But definitely processing capability will be the issue. Even with FIFO
enabled processor will get interrupts for every 20micro seconds. With
processor running at 150MHz, flash based code can run at 90-100MIPS.
Whats the time requirement for other tasks?

Hi, friends

I am designing a interface between F2812 and LCD driver MM5452. This driver
require two signal from DSP: one is Serial Data , the other is CLOCK.

Anybody know how to generate a CLOCK signal to LCD driver.

The following is the LCD driver data sheet.

Thanks

mostly your MM5452 needs SPI communication which is serial.
SPI generates clock along with the communication stream.
there is a SPI port available in 2812 .
all you need is to program appropriately

Jagadish is correct, you can use SPI port to read/write data to LCD
controler. In case if your hardware is already done and and LCD is
not connected to SPI lines as required, you have to use the pins
connected as gpio lines and generate the clock and data on port pins
by setting/clearing appropriately. search google for "software spi
code"
here is a sample link..

i didn't check the data sheet for lcd controller.
