to enable spectum view press flash light button
hold up or down key to change center frequency
press 8 / 2 for zoom in / zoom out
press 1 / 7 to increase / decrease resolution (smaller resolution == faster update rate)
press PTT or EXIT to disable spectrum view

flash masking and memory layout

Chinese mcu DP32G030 has feature called flash masking, here is how it works:

libs/k5_uv_system (par_runner)

The idea is to run this firmware 'parallel' with the original Quencheng firmware. This can be achieved by relocating the original vector table to the end of the original firmware, and placing a new vector table at the beginning, with entities pointing to the par_runner functions that wrap the original firmware handlers.
Every interrupt is first processed by the par_runner handlers, which can perform some tasks, before invoking the original firmware handler

flash memory layout

When building the "par_runner" target automaticly "bootloader" target will be build building UV_K5_Playground target will result in following outputs:

target.bin / .hex - right part of image, can be used to generate encrypted firmware compatible with orginal Quescheng update tool
bootloader.bin - stripped bootloader from orginal firmware
target_with_bootloader.bin - complete firmware image
target_encoded.bin - encrypted binary that can be uploaded through quancheng upload tool

To change the original firmware that will be wrapped and placed into the original firmware section, replace ./original_fw/original_fw.bin or set the variable CMakeLists.txt set(ORGINAL_FW_BIN orginal_fw.bin) in ./orginal_fw/CMakeLists.txt and rebuild par_runner

build system installation

currently tested on windows, requred:

arm-none-eabi-gcc
python (i have newest version)
cmake
ninja
open-ocd

All folders with executables of the above programs should be added to the PATH environment variable.

After cloning repo init submodules:
$ git submodule update --init --recursive
install dependencies needed by fw_pack.py
$ pip install pyserial

for debugging:

vs code
- Cortex-Debug plugin
- CMake plugin

building

via terminal

$ mkdir build $ cd build $ cmake ../ -G Ninja
for all targets:
$ ninja
for specific target:
$ ninja target_name
current targets: pong, rssi_printer, rssi_sbar, messenger, most_useless_mod, spectrum
to build binary that can be uploaded by quancheng fw update tool use _encoded suffix for example:
$ ninja rssi_sbar_encoded

uploading via openocd

$ ninja rssi_sbar_flash

via VS Code

Select the specific build target in the bottom bar and press build.

uploading

Enter the 'Run & Debug' tab, select 'kwaczek DBG', and press run.

Tutorial for building Piotr FW online

ALL COMMANDS ARE RUN IN THE CODESPACE, nothing modifies you pc, don't run any command on your local pc
you need a github account
open your codespaces: https://github.com/codespaces
- click on "New codespace"
  - Repository: piotr022/UV_K5_playground
  - Branch: main
  - Region/Machine type: Doesn't matter
execute sh -c "$(curl -fsSL https://raw.githubusercontent.com/manujedi/UV_K5-Tools/main/TutOnlineEnv/SetupGCC.sh)" in the Terminal (or run the commands by hand to see what they do)
- this takes some time (about 1min)
- your codespace should stop (if not select the codespace and press enter), click restart
Build the FW (do not use ninja, replace ninja with make. Commands are similar to the ones in the README):
- mkdir build
- cd build
- cmake ..
- make
- make rssi_sbar_encoded

You should have now a full development environment
