You can certainly do a software PWM at those frequencies. Just think of a pin thats off 100% of the time, on 50%, off 50%, or on 100%. That should be pretty easy with any timer. You would make the R-C time constant many times the period of the PWM repetition period. There is LOTS

Generally, a device that uses SD card can use mmc but not vice versa. This is because, SD card has an extra pin which I think is for security purpose. Thus, if you put in a SD card into a mmc slot (which is one pin less), you won't be able to read it. Another important thing to l
