+## Dev
+
+### Env Setup
+
+From build folder run:
+
+```shell
+$ cmake -DPICO_BOARD=pico_w ..
+```
+
+This creates the needed makefiles
+
+### Build
+
+This turns the test.c file in the root dir into .elf and .uf2 files:
+
+```shell
+$ make node1
+```
+
+### Flash
+
+Once you have the .uf2 file you can transfer it to the pico by putting the pico
+in bootsel mode (hold button and plug it into pc) or you can flash the .elf file
+to the pico using `openocd`:
+
+```shell
+openocd -f interface/cmsis-dap.cfg -f target/rp2040.cfg -c "adapter speed 5000" -c "program node1.elf verify reset exit"
+```
+
+*note: after flashing with openocd the program will be paused. To unpause connect and run "continue"*
+
+### Shell
+
+You screen
+
+```shell
+$ fd tty.usb /dev
+/dev/tty.usbmodem102
+$ screen /dev/tty.usbmodem102 115200
+```
+
+Exit shell Ctrl+A Ctrl+|
+
+### Open debug connection
+
+```shell
+$ openocd -f interface/cmsis-dap.cfg -f target/rp2040.cfg -c "adapter speed 5000"
+```
+
+then in another window
+
+```shell
+$ lldb ./test.elf
+```
+
+Once in lldb you can do a bunch of stuff, see https://web.navan.dev/posts/2024-08-08-openocd-macos-lldb.html.
+
+
+```shell
+(lldb) platform select remote-gdb-server
+...
+(lldb) process connect connect://localhost:3333
+```
+
+Set breakpoint:
+
+```shell
+(lldb) breakpoint set --hardware --name main
+(lldb) continue # Continue execution
+(lldb) step     # Step in
+(lldb) next     # Step over
+(lldb) finish   # Step out
+```
+
+Check vars:
+
+```shell
+(lldb) frame variable
+(lldb) print variable_name
+```
+
+Restarting the program:
+
+```shell
+(lldb) process plugin packet monitor reset run
+```
