Hi all I need to a transfer a file(*.txt)over the UART from the blackfin board. I have seen the sample assembly program but it is highly confusing.can anyone plz send me a sample C code of one such(any tranfers via UART). Thanks in advance Sriram __________________________________ |

Hi I have an example assembly code for BF532 so i think u can use it. .global _UART_Tx_Configuration; _UART_Tx_Configuration: P0.H = (DMA7_PERIPHERAL_MAP >> 16) & 0xFFFF; P0.L = DMA7_PERIPHERAL_MAP & 0xFFFF; R0 = 0x7000; W[P0] = R0; ssync; P0.H = (UART_GCTL >> 16) & 0xFFFF; P0.L = UART_GCTL & 0xFFFF; R0=0x1; W[P0] = R0.L; ssync; P0.H = (UART_LCR >> 16) & 0xFFFF; P0.L = UART_LCR & 0xFFFF; R0 = 0x0000; W[P0] = R0.L; ssync; P0.H = (UART_IER >> 16) & 0xFFFF; P0.L = UART_IER & 0xFFFF; R0 = 0x0003; W[P0] = R0.L; ssync; P0.H = (DMA7_CONFIG >> 16) & 0xFFFF; P0.L = DMA7_CONFIG & 0xFFFF; R0 = 0x1000; W[P0] = R0; ssync; R0.H = _uart_tx_buffer; /* Address of character array*/ R0.L = _uart_tx_buffer; P0.H = (DMA7_START_ADDR >> 16) & 0xFFFF; P0.L = DMA7_START_ADDR & 0xFFFF; [P0] = R0; ssync; P0.H = (DMA7_X_COUNT >> 16) & 0xFFFF; P0.L = DMA7_X_COUNT & 0xFFFF; R0 = 0x80; /* Count to be loaded */ W[P0] = R0.L; ssync; P0.H = (DMA7_X_MODIFY >> 16) & 0xFFFF; P0.L = DMA7_X_MODIFY & 0xFFFF; R0 = 0x1; W[P0] = R0.L; ssync; P0.H = (UART_LCR >> 16) & 0xFFFF; P0.L = UART_LCR & 0xFFFF; R0 = 0x0080; /*8 bits, 1 stop bit,no parity*/ W[P0] = R0.L; ssync; P0.H = (UART_DLL >> 16) & 0xFFFF; P0.L = UART_DLL & 0xFFFF; R0 = 0x28b; /* Here system Clock is at 100Mhz*/ W[P0] = R0.L; ssync; P0.H = (UART_DLH >> 16) & 0xFFFF; P0.L = UART_DLH & 0xFFFF; R0=R0>>8; W[P0] = R0.L; ssync; P0.H = (UART_LCR >> 16) & 0xFFFF; P0.L = UART_LCR & 0xFFFF; R0 = 0x0003; W[P0] = R0.L; ssync; P0.H = (DMA7_CONFIG >> 16) & 0xFFFF; P0.L = DMA7_CONFIG & 0xFFFF; R0 = 0x1001; W[P0] = R0; ssync; RTS; --- sriram K <> wrote: > Hi all > I need to a transfer a file(*.txt)over the UART from > the blackfin board. > I have seen the sample assembly program but it is > highly confusing.can anyone plz send me a sample C > code of one such(any tranfers via UART). > Thanks in advance > Sriram > > __________________________________ > > _____________________________________ > /groups.php3 __________________________________ |

Not a ADI DSP question - h h - Sep 16 15:24:00 2003

but I may as well ask anyways. If you have ever worked with ARM DSP, what development tools would you recommend? Thanks. hh_ca |

Hi all I have a very simple Q....I trying to run the UART Hyperterminal program that has come along with the 533 Blackfin Kit.....I was able to start a hyperterminal program..Perform Autobaud detection......but when i type any cahrecter or string and want to see the charecter echo back ....i do not get the echo (I am typing the string followed by the ENTER key on the keyboard...)but i do not see the echo.... Thanks in advance Regards Sriram __________________________________ |

Hi Sriram, I do not know about the Blackfin kit, but I know little bit about the Hyperterminal. If your question is regarding "How to see the characters that we typed on Hyperterminal", please proceed further. Otherwise, ignore the rest of this mail. To get the echo on Hyperterminal, you need to enable the "Echo typed character locally". After configuring the Hyperterminal go to File->Properties->settings->ASCII Setup In that enable the check box, Echo typed character locally.

hi I need to disable the echo mode in the hyperterminal.....which i did because the adsp has to echo the charecter back......
