UART receive DMA with ISR

Hi anuradha,

to work with 48 Mhz you have to configure the clock as follow:

SCU_PLLFactorsConfig(192, 25, 3);

SCU_PLLCmd(ENABLE);

SCU_RCLKDivisorConfig(SCU_RCLK_Div1);

SCU_HCLKDivisorConfig(SCU_HCLK_Div1);

SCU_PCLKDivisorConfig(SCU_PCLK_Div2);

SCU_FMICLKDivisorConfig(SCU_FMICLK_Div1);

SCU_MCLKSourceConfig(SCU_MCLK_PLL);

so you have to enable the PLL before selecting the source clock . This configuration works well for me: I've obtained 48Mhz frequency and I was able to send data to hyperterminal.

I hope this can be usefull for you.

Best regards

Hi anuradha,

I tested your code with MCB-STR9 board and it works well for me. May be you configured wrong the hyperteminal utility.

You find attached the hyperteminal configuration that I've used.

hai mirou,

i have used u'r hyper terminal file but it is also same as my file.

thank u to conformed that my program is working.

i have tried it in some other system (Hyperterminal), but no use.

i could not find the mistake where actual problem is?

please send me the complete project so that i will find my problem whether it is in Startup code or some where else. its better for me to have a working program.

Thanks for u'r constant help.

regards

raj.

hai mirou,

we are using MCB-STR9 Vers.3 Evaluation Board.

On which board u r tested my code?

according to program i think so there is no mistake.

what are the other areas which may cause problem?

please send me the UART working Example project file.

thanks & Regards

Raj.

hai Zouh,

yes we are using crossover cable (2-3, 3-2, 5-5 of db connector).

we are using Keil uVision3.03a software for Debug.

did u check my code?
