5 FAQs about [Debugging of solar panel controller]
How do I read data from srne solar charge controllers?
Read data from SRNE solar charge controllers via modbus over RS232. This repository contains several example programs for reading data from SRNE solar charge controllers using Raspberry Pi, ESP32, ESP8266 and Arduino Nano / Uno. Based on the modbus manuals, this should also work with some Renogy controllers, but I don't have one to test with.
How to debug STM32 microcontrollers?
For development with STM32 microcontrollers, usually the ST-Link in-circuit debugger is used for programming. All ST Nucleo development boards include an integrated ST-Link/V2 debug adapter. The boards are very cheap and allow not only firmware upgrade but also debugging via the SWD interface (see also section Debugging ).
What is Serial Wire Debug (SWD)?
Microcontrollers based on ARM Cortex-M like the STM32 series feature the Serial Wire Debug (SWD) interface for programming and debugging. This is the most common architecture for 32-bit Microcontrollers and is also used in the Libre Solar charge controllers and other devices, so the following sections focus on programming via SWD.
What are the best debugging tools for SWD?
For more advanced debugging purposes, the commercial Segger J-Link is a very popular tool. The main advantage is probably the software provided by Segger that can only be used together with the J-Link. Another very popular programmer and debug probe for SWD is the Black Magic Probe.
What are the advantages of using a debugger?
Debugging with PlatformIO and VS Code. The biggest advantages of using a debugger instead of serial prints: The firmware execution can be stopped at defined break points in order to analyze the state of the memory at this point.
