Hi,
I am planning on the following project;
1) Receive NMEA string from Adafruit Ultimate GPS via serial1 pin0 RX pin.
2) Ammend NMEA string in teensy3.1 code.
3) Broadcast NMEA though wifi (maybe XBEE).
This project wouldn't be so bad but I am trying to utilise DMA as I should be able to utilise the 4 available channels.
I have Java and C code experience and have used teensy3.1 for various smaller projects.
But, programming with DMA I am not that confident with.
Is there a basic 'mudmap' that can assist in this cause on the process such as flag requests, interrupts etc. that could greatly assist.
I have MATLAB reading the NMEA strings using Serial.println() etc but this process is too slow, hance the DMA requirements.
Thanks.
