Hi, I am using the GPIO pins of the DM648 DSP. I am able to write and clear the GPIO SET_DATA and CLR_DATA registers of the GPIO peripheral and toggle the GPIO pins. But I want to receive the GPIO interrupt to the CPU. I am able to understand that the GPIO interrupt registers can be configured for both rising and falling edge interrupts, but can anyone help me on how to configure the HWI mod...

HI Does anyone know how to use GPIO pin to be a clock output? I have try to set the "GPIO high----GPIO low_____GPIO high----GPIO low_____" to simulate the clock output. But that always give me some extra overheads that makes the clock unreliable. As you know the accuracy of the clock is important. Anyone have any idea how to use GPIO pin as clock output? All suggestions are welcome. Any help w...

Hello everybody, I'm working on a TMS320C6455 DSK board and I want to use the muxed GPIO/McBSP1 pins as GPIO, for both input and output. As a test I tried to toggle one of those pins in order to have a pseudo-clock signal on the pins of the J3 connector that are shared by GPIO and McBSP1 interfaces. Since the latter is enabled at startup of the board and is set to communicate with the AIC23 aud...

Hi, I am implementing a design using the MsASP configured as GPIO and the GPIO module itself. I saw that it is possible to access the McASP pinouts through the HPI Expansion Connector on the dsk but I dont know how to access the GPIO pinout.

Hi. I'm trying getting to run an interrupt on falling edge from GPIO using the OMAP-L137 EVM and PSP drivers 1.20. I use the GPIO2[13] (on ASFX0). I get a successfully created GPIO handle, but the interrupt is never triggered. I've checked the input signal on the scope, it's like follows: it's periodic and 3.3V (though quite noisy, noise between 2.9V and 3.6V) during ~16 ms and then goes ...

Hi all, I was searching all the tutorial given by TI-DSP, but no where it is given clearly how to add a GPIO pin as a HWI. I am working with EVM-DM6437 board. In this board there is IO expander which gives a interrupt signal to the DM6437 GPIO pin:GP[4]. I want to detect this interrupt as a HWI and run a ISR. Is any one who has done this before can help to configure a gpio (say GP[4])...

Hi, I use GPIO to generate output signals with a minimum high pulse width of 240ns. I must use NOP for the timing, because I have no free timer. So I entered 72 NOPs (300MHz) delay and I got a pulse width of 180ns! It looks like there is a GPIO internal timing which is much slower than SYSCLK1. I had to adjust the number of NOPs (now 90), but I can live with it. Then I turned compi
