Hi everybody, I had encountered a problem while 'load program' when trying to load F2812 using CCS V.2. The following error was observed. " Unexpected Fatal error encountered which may be have been caused by stack overflow, out of memory condition or access violation." At this time, the loader window showed: "Setting PC to entry point". Using some computers I could load t...

Dear all, I'm new in DSP. I am working on a TMS320F2812 DSP (on a Spectum Digital eZdsp board). I have to write an application that do the following tasks (or parallel execution paths): 1 - read data from external ADCs (then apply on this data an algorithm) connected to GPIO ports 2 - send periodically elaborated data on SCI UART interface 3 - read other data from on-chip ADC (like te...
Signal arrival detection

Hi all, I am trying to detect the precise arrival time of a signal. It is exponential in nature and is generated from an accelerometer. It has considerable white/electrical noise on the line already so I have filtered this out with a low pass 254 order FIR. I realise this is a huge filter but it gives a good sharp transition and the data is all post processed anyway. Unfortunately there...

What is the purpose of FXN_F_selfLoop?

I have inherited a project that I'm trying to get working. Unfortunately, the program flow sometimes goes to FXN_F_selfLoop. The code here is as follows: FXN_F_selfLoop: SB FXN_F_selfLoop,UNC This is an unconditional branch to itself, so when it gets here, it's basically running an infinite loop. Nothing appears to happen after this point is reached. I've tried googling FXN_F_selfLoop ...
Use of timer2 and INT14
Hi to all has anyone of You ever used timer2 and its interrupt INT14? I'm not using DSPBIOS nor RTOS and I need to use timer2; but, when the...
Hi to all has anyone of You ever used timer2 and its interrupt INT14? I'm not using DSPBIOS nor RTOS and I need to use timer2; but, when the interrupt of timer 2 is on, the Program Counter goes to a wrong place in the code space. I can't understand if I'm mistaking something when setting INT14 or in the loading of the ISR address in the correct place or if there are any limitations ...

I bought the eZ DSP TM320F2812, ok cool! I set the port to 0x378 in SPP8 mode, to verify I got this $$ You are connected to: $$ EmuProductName=XDS510PP_PLUS $$ EmuPortAddr=0x378 $$ EmuPortMode=SPP8 $$ ProductId=10 $$ ProductVersion=84 but when I try to test the emulator I got this message: ** Emulator Test ** $$ EmuProductName=XDS510PP_PLUS $$ EmuPortAddr=0x378 $$ Em...
F2808 Flash programming via RS232

Hello everybody, I'm using an eZdsp starter kit for TMS320F2808. I'm trying to program flash memory via RS232, using SDFlash utility or CodeSkin C2000Prog. I have set the board for SCI Boot Mode. The problem: after DSP power reset, the utility (SDFlash or C2000Prog) starts sending the autobaud character 'A', but the DSP doesn't echo back the character, so the utility cannot start the the b...

Hi All, I have a query regarding the usage of capture input pin in TMS320F2808. The question is as follows 1. I've configured Capture Input 1 to trigger an interrupt on any one of the four capture events (CEVT1-CEVT4). 2. The polarity of the event (Rising Edge, RE or Falling Edge, FE) is also configurable by writing to the capture control register ECCTL1. I've configured CEVT1 & CEV...
