Hi Erik,
That is right, AFAIK all RS485 implementations on NuttX use this approach
(even for ESP32).
This solution was created by Freddie Chopin many years ago for STM32.
I think this approach is similar to the way NuttX supports SPI CS pins, so
you have more flexibility to use any pin you want.
Hi Alan!
Native hw-controlled rts would ofcourse be the cleanest solution, but this
project is not very timing critical so the software solution you suggest
will most likely be sufficient!
Thanks for pointing that out, i´ll just do it that way instead, to get
going.
But this also raises the quest
Hi Erik,
Do you want to implement it using the native HW from serial controller to
support RS485 or do you just want RS485 and it could be implemented as in
other MCUs where after detecting transfer complete we control the DE/RE pin?
If the later is OK for you, then please take a look how it was
Yes, i put ESP32C3 in the subject to the maillist, but maybe it was omitted?
Im building with boardconfig esp32c3-generic and the wifi config, so the
common implementation is used.
(
for a common build theres quite a lot of header files:
arch/risc-v$ find -name uart_ll.h
./src/esp32c3/esp-hal-3rdp

IMHO, It's still too restrictive.
Hello,
The network interface could have been developed over the generic radio
interface I developed to write the char driver.
And this network interface would have been generic, so write once,
instanciate with all radios.
My argument was exactly that network interfaces are overkill and
req
Hi Sebastian, it's a pity that your radio framework didn't go upstream.
The lack of a standardized interface for radios is a problem now.
Network interface for small radios, especially for LORA radios is overkill.
I think Greg later admitted that because he accepted sx127x as a character
driver. Th
