* backport SPIPortManager from @skippermeister
* adapt to support ESP32 and ESP32-S3 and ESP32-C3
* use logic to work with SPI numbering as in the official
documentation: start with SPI0 and go up to SPI3
* increase Huawei CAN controller stack size to 2000
* increase startup delay for USB_CDC enabled builds to be able to
catch bootlogs over USB
Hoymiles inverters allow setting relative limits with a precision of 0.1 %.
this changeset allows to utilize this precision.
* preserve accuracy when decoding power limit
* Web API: process floating point limits
* MQTT: process floating point limits
* use appropriate accuracy for limits in web UI
* HASS: step for relative inverter limit is 0.1 %
implement a function which allows to reset the SML decoder. this new
function is used after a datagram ends. for the SML HTTP power meter
this is simple: after all bytes from the request's answer have been
decoded, we reset the decoder. for the SML serial power meter, we
perform the reset after a datagram ended based on timing (no new bytes
have been received for a specific amount of time).
the comparison is part of the original library code, but the compiler
rightfully complains that the comparison byte <= 0xFF is always true,
since byte is uint8_t. the comparison was commented out, and is now
removed.
a 9600 baud serial interface does not need a hardware UART. these
changes switch the SDM power meter implementation to use a software
serial instance instead. this is desirable as hardware UARTs are scarce
and users need them for JK BMS and VE.Direct interfaces.
avoid additional conversions and avoid double for the fact that
calculations on type double are implemented in software, whereas
float is handled in hardware on ESP32.
only on ESP32-S3-USB. this fiddles with the available hardware UARTs to
make it possible to use a third Victron MPPT. if three MPPTs are defined
int the pin mapping, you will not be able to use the SmartShunt and JK
BMS battery interfaces.
note that using a second MPPT will also conflict with the SDM power
meter, and that conflict is not detected, yet.
