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 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

GPIO on 5509a timing

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.

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

Does there has any method to rise the clock frequency up to about 10MHz? I tried ch...
