In this issue, the editor will bring you about the new content released by RT-Thread 3.0.4. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

RT-Thread is basically moving forward at an established pace. Nearly a quarter has passed since the last version was released, and v3.0.4 will be released in the middle of the year. At the same time, more and more developers have joined the construction of RT-Thread, such as Sugar, liuguang,zhuangwei,bluebear, Sun Dongmei and other developers have also made a lot of contributions.

The following is mainly divided into two parts: the new version release and the community to make an introduction.

New version released

Compared with RT-Thread 3.0.3, the change of RT-Thread 3.0.4 is not big, and part of it is the adjustment of bsp. The major changes include:

Better Godson 1C BSP: on the Godson 1C Smart Dragon development board, RT-Thread can no longer run without pmon. At present, Godson 1C BSP is also relatively sound, you can purchase a set of Godson 1C300 development board to support our country's Godson processor.

More complete i.MX RT1052 BSP driver support, basically (except for camera driver) a complete set of drivers

Detection of GNU GCC versions and libc features to minimize compilation problems caused by different versions of GCC

The other changes are mainly peripheral changes. After the release of v3.0.4, the master backbone on github began to merge the changes from the v3.1.0 development branch one after another, while v3.0.4 will continue to be maintained as a v3.0.x branch.

Kernel

Adjust the location of hook calls in rt_event_send to better reflect the event value to system view.

Fix the rt_realloc problem of memheap

Add GPIO driver support on i.MX RT1052

Add RTC driver support on i.MX RT1052

Improve SD/MMC driver support on i.MX RT1052

On i.MX RT1052, add SPI driver, SPI Flash driver (docking to SFUD component) support

Add USB Device driver support on i.MX RT1052

Add README documents and KConfig files to LPC408x BSP

Add README documents to LPC5460x-LPCXpresso BSP

Add display controller driver (Sundm75) to Godson 1C BSP

Add CAN driver (Sundm75) to Godson 1C BSP

GPIO driver in Godson 1C BSP, added (external) interrupt support (zhuangwei)

Add SPI automatic initialization function to Godson 1C BSP

Add I2C driver (Sundm75) to Godson 1C BSP

Add resistive touch screen driver (Sundm75) to Godson 1C BSP

In Godson 1C BSP, the component is automatically initialized, and the user entry becomes a main function (zhuangwei).

Add Flash self-startup support (zhuangwei) to Godson 1C BSP

Add README documents and KConfig files to Godson 1C BSP, and do more explicit initialization work (zhuangwei)

Add README description file to stm32l476-nucleo BSP

Because V2M-MPS2 does not support 32-bit emulation, temporarily remove this BSP

Add README documentation and some firmware to be used in X1000 BSP, such as u-boot.bin, etc.

Tools

Added version of GNU GCC tool chain and automatic detection of libc features

Add the auxiliary function of VSCode editor, support scons under bsp-- target=vsc-s will generate configuration files suitable for VSCode use

Add the function of IAR version detection

Add ProjectInfo (env) function to get all files compiled at once, all header files, all macro definitions, all header file search paths, etc. It is also convenient to provide more appropriate auxiliary functions for different IDE tools.
