|
TransmitBusy |
| Checks to see if the RMT channel is currently transmitting. Returns 1 if transmitting and 0 if transmission is complete. | |
 - BYTE
|
Return |
|
|
SetBuffer |
| Writes data to the RMT buffer | |
 - UINT
|
Index |
| Array index, Range: 0 - (BufferSize - 1) | |
 - BOOL
|
State0 |
| The first state to output | |
| - UINT
|
Length0 |
| The length of the first output state in divided clock periods | |
| - BOOL
|
State1 |
| The second state to output | |
| - UINT
|
Length1 |
| The length of the second output state in divided clock periods | |
 - VOID
|
Return |
|
|
Transmit |
| Sends out the RMT data buffer. | |
| - BYTE
|
WaitWhileComplete |
| 0=Dont Wait, 1=Wait for TX to complete | |
| - VOID
|
Return |
|
|
Initialise |
| Initialises the RMT module ready for data to be sent or received. | |
| - VOID
|
Return |
Property reference
|
Properties |
|
Mode |
| Controls if we are transmitting or receiving data | |
|
Pin |
| Pin to assign the RMT functionality | |
|
Clock Divider |
| Base Clock speed is 80MHz. Div by 1 = 80MHz Div by 2 = 40MHz Div by 4 = 20MHz Div by 8 = 10MHz | |
|
|
Mem Block Num |
| Starting RMT memory block | |
|
|
Buffer Size |
| Number of values inside the data buffer, 64 = 1 Block A buffer size of 128 would consume two sequential blocks of memory. If starting at block 1 then you can have a maximum buffer size of 512 consuming all 8 blocks. | |
|
Tx Properties |
|
TX Loop Enable |
| Allows the transmit buffer to be constantly looped. | |
|
|
TX Carrier Enable |
| Enables a carrier frequency to be overlaid on the transmitted data | |
|
|
TX Idle Output |
| When not transmitting should the Transmit pin be an active output? | |
|
|
TX Idle Level |
| Sets the output state when idle. | |
