i configure all the interrupt in DSP/BIOS, i use timer to generate a sync signal output at gpio 11, so it works and the gpio output a sync signal which is 10 ms 1 and 990 ms 0 until i stop it. i set gpio 10 as a input pin and let it trigerred a interrupt when it encount a rising edge. inside the interrupt routine i let variant count increas 1 when gpio is triggered.however, the gpio only trigger ...

I remember that there are some examples about GPIO in CCS folder but I can not find them now. Is there anybody know how I can find an example on using GPIO? Cheerz.

It has been awhile since I have used the C55 family and I can't remember if they support using the HPI as GPIO if you are not using the HPI. I seem to recall that some of the TI DSPs can do that, but I don't see anything in the docs that says the C5510 is capable of it. Anyone know for sure if the C5510 HPI can be used as GPIO?

Hi, I am Ang Teik Boon from University Teknologi Malaysia I am currently doing my final year project using dsp starter kit, so i plan to send a signal from the microcontroller to the dsp board through GPIO module.Thus does any body know how to use GPIO module in the csl library on tms320vc5510DSK board . what i want to your help is very simple i just want to know how to co...

Hi everbody! I've encountered a strange problem on my 5509 EVM. The display uses GPIO 4 to indicate weather it's busy (low) or not (high). To read that bit is no problem before I call the dsplib rfft algorithm, but after it doesn't work. CCS says GPIO 4 high but still the program hangs on this instruction: while( !(pGPIO-> iodata & GPIO_4)); Seems

I have an SDRAM (MT48LC8M16A2TG) connected to 5509A and willing to use pin 16, 22 and 25 which are GPIO 8, 10, 11 respectively, as general purpose output pins. Trying all but could not change their state as I can easily do with GPIO7. I will be happy if you will help me.

Hi, I have a questions about GPIO timing when I toggle them. It takes one cycle to change the pin high and one cycle to set it back to low. So when the DSP is clocked with 48 Mhz and I measure the pin with a logic analyzer I would expect to see a delta of about < 50ns. But what I measure is something > 200ns. Are there any explanations for this? Is the peripheral bus the reason?

Hi all, I have configured the McBSP #1 as GPIO (RRST_ = 0 RIOEN = 1). When I read the voltage on that pin (the pin is not connected, working with 5509 EVM from Spectrum Digital), I read 0 but the DSP read a logical 1 If I link the pin to the ground, the DSP sees a 0.

Hi all! I have a pice of code that worked fine on CCS2.12, but after "upgrading" to CCS2.21 I can't make it work. It sounds simple and strait-forward to enable the GPIO using GUI- Config-tool (.cdb file) through CSL, BUT look at what I got... If someone could, please,

I am using the C5510 and want to use the GPIO pins in an open collector mode. I know that in general, it is possible to set the output data register to a 0 and toggle the output enable (direction) bit to allow the output to drive a 0 or to tristate and let a pullup put a 1 on the signal. But the info in the C5510 data book is not clear if you can do this without driving a 1 momentarily. I

Hi, I have configured McBSP1 pins DX1, DR1, FSX1, CLKX1 on DSK5509 as GPIO pins. In order to communication with external RF chip I needed to drive CLKX1 functioned as clock. It successfully worked by writing feild CLKXP in register PCR high and then low. However, the frequency of this clock is about 0.4MHz. Does there has any method to rise the clock frequency up to about 10MHz? I tried ch...

Hi, I am trying to get UART serial boot to work on a C5502, I have set the DSP GPIO for Uart boot and see GPIO4 go high then low as expected, I send my bootloader at the required baud rate and get an exact match echoed back but then nothing happens. If I look at DARAM in code composer after loading it doesn't look right and I have tried various Hex55 combinations without any luck. Some H...
