Part Number:TMDSDOCK28379D
Hi,
I'm currently making a breakout board for motor control applications with the specified control card and I had some general questions:
- Are there any other pins that can be configured as ADC inputs? I see from the attached pinout diagram that I can use select pins in the range of pins 9 through 42 (excluding GND pins). This sums up to 24 ADC pins, but I am wondering if it is possible for me to access more than 24 ADC's (perhaps using software) and if so, what pins are those?
- Which pins can be used as ePWM outputs? Same question as above, I have found 16 of the PWM pins, and am wondering if there are other pins that are configurable to become ePWM or PWM pins so that I can use more than 16 of these types of signals. On the datasheet, it says there are 24 PWM channels, 16 HRPWM channels; what pins are those that are hiding from the attached pinout diagram?
- With respect to the ADC pins again, is there a special functionality with pins ADC14 and ADC15? Just curious why they have a different naming format from all the other ADC pins and if I can use them as normal ADC pins.
- Are there any particular grounds that are intended to be used as analog grounds? All of the grounds are internally connected on the control card, so I'm wondering if I can use any ground I want as a dedicated "AGND" or if this matter at all and I can just connect the AGND and GND pins on my board I'm making since they will all eventually get shorted inside the control card anyways.
- Can any pin I want be configured as TZ pins, and if so do they all share the same functionality? I ideally want to use a quantity that is equal to half of the number of total pwm pins. For example if there are 16 PWM pins I want 8 eCAP pins.
- Can I use any other pins as eCAP pins other than the four specified on GPIO pins 24-27? I ideally want to use a quantity that is equal to half of the number of total pwm pins. For example if there are 16 PWM pins I want 8 eCAP pins.
- Does the reset pin (pin 120) on the board clear the ram? If I write a program to the device and click the reset pin, am I going to have to reflash my program again, or does it work similar to an arduino?
I have attached the pinout diagram I used to assemble my board as well as my current schematic of the pins I am using if that helps clear up what I am talking about.
