0x00 System Introduction The new version of the system released this time is compiled by updating all ROS package source codes to the latest version, and no new ROS packages have been compiled. This new version does not have any highlights, as the previous version 1.8 was released more than half a year ago; this … Read more
0x00 Introduction to V1.4 Version Image The upgrade of this version image is mainly to adapt to the newly released Raspberry Pi 4 motherboard, as the last released v1.3 version kinetic image could not run on Raspberry Pi 4. The image released this time can run on all models of Raspberry Pi motherboards in the … Read more
1. Why Not GCC When developing STM32, the compilation toolchain must use gcc-arm-none-eabi. Why not GCC?This relates to cross-compilation in Linux, as we need to compile programs that can run on ARM from a PC. Using GCC will compile programs that run on the PC, so we need to use gcc-arm-none-eabi for cross-compilation~ 2. Introduction … Read more
1. Introduction In the previous article, we explained how to use open-source hardware like Arduino and Raspberry Pi to build a real car equipped with ROS (Robot Operating System). This article will continue to guide you step by step on how to implement those powerful ROS packages on our physical car. 2. Added Sensors 1. … Read more
QEMU (Quick EMUlator) is a general-purpose open-source emulator and virtualization tool that can simulate most CPU platforms, such as x86, ARM, ARM64, RISC-V, PowerPC, MIPS, etc. It can also simulate various hardware peripherals, such as memory, emmc, sdcard, usb, etc. Therefore, through QEMU, we can simulate a development board. During the chip development process, chip … Read more
