AGV Side Project Log #4 — STM32 UART Transmission + ROS2 Launch File
The USB-UART converter finally arrived. Sending messages every 1 second over STM32F407's USART2 and confirming reception on the PC serial monitor. Why I'm keeping USART3 for RS485, why I'm starting with blocking, and how to bring up a serial console right inside STM32CubeIDE. Plus running two nodes at once with a ROS2 launch file.
