@ -19,6 +19,10 @@ The library lets you register listeners (callback functions) to wait for (1) any
a particular frame Type, or (3) a specific message ID. This high-level API lets you
easily implement various async communication patterns.
TinyFrame is re-entrant and supports creating multiple instances with the limitation
that their structure (field sizes and checksum type) must be the same. There is a support
for adding multi-threaded access to a shared instance using a mutex (via a callback stub).
## Frame structure
All fields in the message frame have a configurable size (see the top of the header file).
@ -49,7 +53,9 @@ DATA_CKSUM .. checksum, implemented as XOR of all preceding bytes in the message
- All TinyFrame functions, typedefs and macros start with the `TF_` prefix.
- Both peers must include the library with the same parameters (configured at the top of the header file)
- Start by calling `TF_Init()` with `TF_MASTER` or `TF_SLAVE` as the argument
- Start by calling `TF_Init()` with `TF_MASTER` or `TF_SLAVE` as the argument. This creates a handle.
Use `TF_InitStatic()` to avoid the use of malloc(). If multiple instances are used, you can tag them
using the `tf.userdata` / `tf.usertag` field.
- Implement `TF_WriteImpl()` - declared at the bottom of the header file as `extern`.
This function is used by `TF_Send()` and others to write bytes to your UART (or other physical layer).
A frame can be sent in it's entirety, or in multiple parts, depending on its size.
