Re: Cannot get Harmony v2.06 SD Card driver working on a PIC32MZ2064DAH176 processor...
Thank you for the reply,
We don't have any issues with our USB port, it works fine.
We have mapped the card detect, goes low when card is inserted. The write protect line is not connected, was left at default which looks to be A0, we don't have anything connected to that PIN so should not be toggling or anything on us.
We don’t provide 5V power on our USB line, so there is no capacitance on there except 10nF to chassis for filtering.
On the VBUS monitor, there is no 100ohms resistor , it is just connected straight to VBUS. There is no recommendation to do so in the datasheet. However we don't have any issues with the USB port.
We have used the SD card library before on a PIC24 based product, used the same circuit that one does, it works without any issues so we are wondering why the PIC32MZ has an issue...
We are also using the Aria library, which gives us a heap of 19368, tried going to 30,000 and no luck.
Still seems to do the annoying toggle...
