ce9505e670 linux: Unify logging function in esptun 2020-02-22 13:17:40 +00:00
Wladimir J. van der Laan
afde09e6cc linux: Don't set VTIME in UART configuration for esptun 
`read(esp_fd)` should wait for 1 or more characters to be available in
the UART FIFO, no timing required.

c261d4dcc7 linux: Simplify esptun by getting rid of some helper functions 
`cread` and `cwrite` are trivial and only called in one place, so just
integrate them.

7cbb10693e linux: Set timeout argument on poll() properly 
`0` for the timeout means *return immediately* instead of
*wait forever*. This is absolutely unnecessary, so change
the argument to `-1` which does mean *wait until something happens*.

aab7c0a84b linux: Solve an issue with incomplete packets 
esp_read_responses was throwing away the buffer contents between
invocations, which is not a good idea if there might be a (partial)
async notification such a a received packet in there.

526e9683c2 linux: Tune baudrate in esptun 
The maximum baudrate seems unstable at times, tune it down a bit.

885357f22f linux: deduplicate esp receive logic in esptun 
Unify the two similar serial receive loops.
(as a bonus we'll no longer lose packets that come in through the ESP during
esp_tx_packet)

4d987f0d7d rust: Important correction to board definition comment 
WIFI_RX and WIFI_TX are named from the perspective of the ESP8285,
so they need to be connected RX<->TX and TX<->RX to be used.

0e88fae4d2 rust: lock embedded-graphics to 0.6.0-alpha.2 
The API keeps changing significantly between alpha versions, it's too much
work for me to keep updating the demo - I'll update it to 0.6.0 once
there is a release.
