I finally am asking for a bit of help since I cannot solve this myself. I get this error when running example.py (or benchmark.py): Unable to open SPI device: No such file or directory The error occurs when executing this line in pipyadc...
其中<bus_number> 是I2C总线的编号,需要根据实际情况替换。 通过以上步骤,你应该能够定位并解决 "hctosys: unable to open rtc device" 的问题。如果问题仍然存在,可能需要更深入地检查系统配置或寻求专业的技术支持。
I met a SPI device driver (Sitronix st7262) probing problem @ android 13(Kernel version: 5.15.71) In our hardware design, st7262 (panel) is connected to imx8mm via ecspi2 Related DTS &ecspi2 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_ecspi2>; fsl,spi-num-...
I have tried this solution and verified that it works. However, since we use reflection to set the privateresolverfield of theInetAddressclass, we need to openjava.base/java.netmodule to our agent's module for Java 9+. To do that, I have definedJavaNetInitializerclass in thejavaagent-tool...
RTC设备驱动是一个标准的字符设备驱动,应用程序通过open、release、read、write和ioctl等函数完成对RTC设备的操作,关于RTC硬件原理部分我们已经在裸机篇中的第二十五章进行了详细的讲解。 Linux内核将RTC设备抽象为rtc_device结构体,因此RTC设备驱动就是申请并初始化rtc_device,最后将rtc_device注册到Linux内核里面,这样Lin...
Re: ESP32S3 Unable to set specific GPIO as outputs by jgustavoam » Fri Apr 05, 2024 2:17 am What is the ESP32 S3 module model? Caution! May be inappropriate use of GPIO37. ESP32S3 GPIO restrictions : Strapping pin: GPIO0, GPIO3, GPIO45 and GPIO46 are strapping pins. SPI0/...

I am using the SPI PAL to generating code, but there is no textbox to setting the CS pin being continuously LOW. I am unable to set the CS pin being continuous LOW for the daisy chain purpose. If I want to set the CS keeping LOW during the 6 dataframes tra...
Is the problem two different SPI drives (1&2) trying to control the same IO pins? Thanks for the response! Ibelievethat they are using the same SPI device, because the SPI IDs start at 1, and on the ESP32, the SDcard slots are 0-1 for the SD-specific hardware, and 2-3 use SP...
