bcm2835的C库是bcm2835芯片专用的库,在RaspberryPI上使用没有问题,而RaspberryPi2B使用的是bcm2836芯片,虽说bcm2836和bcm2835芯片基本上一模一样,可以拿bcm2835芯片的数据手册,对应bcm2836芯片使用,但是毕竟两个芯片还是有差别的,在这里只针对GPIO的区别简单介绍: 在bcm2835库src/bcm2835.h中GPIO的基地址为:0x2000000...

Programming with the GPIO pins on the Raspberry Pi is typically done using the programming language Python. This particular circuit and code are super easy to get going and won’t take you long at all to complete. GPIO BOARD VS. GPIO BCM ...
工业控制:两者都达到IP20防护等级,但Rock Pi 5的宽温支持(-20°C~85°C)更符合工业需求 七、扩展性与配件兼容性 我测试了主流配件的兼容情况:Raspberry Pi 5的40针GPIO接口兼容率100%,但部分树莓派专用传感器仍需转接板。Rock Pi 5的Type-C接口支持PD快充,实测30分钟可充满5000mAh移动电源。不过当同时使用USB...

and are much better quality anyway, so that is recommended if you happen to need sound. The on-board sound uses a timing circuit that the RGB-Matrix needs (it seems in some distributions, such as arch-linux, this is not enough and you need to explicitly blacklist the snd_bcm2835 module...

Raspberry pico 是一款双核cortex-m0的处理器,在RT-Thread提供的bsp中目前是默认采用libcpu/arm/cortex-m0,其并没有对多核进行支持。在Coremark的测试中pico的性能很一般,只用一个核心实在是太浪费了,所以下面用一种不太优雅的方式基本实现Pico的SMP,简单测试没有问题
