Build Firmware / Build stm32-teslacharger (pull_request) Successful in 59s
Pairs with stm32-hal-vcu PR #42. Adds a runtime "vcuchglim" param that the VCU broadcasts every 200 ms; on receipt, the param's Change() callback translates 20-100% to the charger's udcspnt (DC voltage setpoint) using a linear cell-voltage ramp. Without this, the teslacharger had no path for the user's app-set charge limit to actually limit charging — udcspnt was effectively a compile-time setpoint. What's added ------------ - Param::vcuchglim in include/param_prj.h: PARAM_ENTRY(CAT_CHARGER, vcuchglim, "%", 20, 100, 80, 23) - Range 20-100 (matches VCU validation) - Default 80% if VCU never connects - ID 23 (next free per the comment, bumped to 24) - Saveable so a flashed charger paired with a silent VCU still behaves predictably across reboots - can->AddRecv(Param::vcuchglim, 0x212, 0, 8, 1) registration in ChargerCAN::MapMessages() — libopeninv's CanMap dispatches to the Change() callback on each received frame. - Param::Change(vcuchglim) handler in src/main.cpp: cell_target = 3.30 + (4.15 - 3.30) * (pct - 20) / 80 udcspnt = cell_target * 96 Endpoints chosen to be safe across Tesla LDU / VW MEB / Volt2: 20% → 3.30 V/cell × 96 = 316.8 V (deep-cycle storage floor) 80% → 3.94 V/cell × 96 = 378.0 V (recommended daily ceiling) 100% → 4.15 V/cell × 96 = 398.4 V (matches existing udclim default) Tuneable here as constants if a particular pack needs a tighter range. - VER bump 1.19.R → 1.20.R. Combined with the pre-existing -S1 suffix the OI web UI shows "4=1.20.R-S1", visually distinct from upstream and from the previous Skudak build. Build ----- text=25288, links clean. The "RWX LOAD segment" linker warning is pre-existing on this template, unrelated. No new warnings from this change. Version string in the binary verified as "4=1.20.R-S1".

/* This file contains all parameters used in your project
|
|
* See main.cpp on how to access them.
|
|
* If a parameters unit is of format "0=Choice, 1=AnotherChoice" etc.
|
|
* It will be displayed as a dropdown in the web interface
|
|
* If it is a spot value, the decimal is translated to the name, i.e. 0 becomes "Choice"
|
|
* If the enum values are powers of two, they will be displayed as flags, example
|
|
* "0=None, 1=Flag1, 2=Flag2, 4=Flag3, 8=Flag4" and the value is 5.
|
|
* It means that Flag1 and Flag3 are active -> Display "Flag1 | Flag3"
|
|
*
|
|
* Every parameter/value has a unique ID that must never change. This is used when loading parameters
|
|
* from flash, so even across firmware versions saved parameters in flash can always be mapped
|
|
* back to our list here. If a new value is added, it will receive its default value
|
|
* because it will not be found in flash.
|
|
* The unique ID is also used in the CAN module, to be able to recover the CAN map
|
|
* no matter which firmware version saved it to flash.
|
|
* Make sure to keep track of your ids and avoid duplicates. Also don't re-assign
|
|
* IDs from deleted parameters because you will end up loading some random value
|
|
* into your new parameter!
|
|
* IDs are 16 bit, so 65535 is the maximum
