spidev测试方法howtotestspidev 在设备树中配置spidev 首先需要在设备树配置好spi设备。可参考如下配置 &ecspi3 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_ecspi3>; cs-gpios = <&gpio1 20 GPIO_ACTIVE_LOW>; dmas = <&sdma 7 8 0>, ...

I am a newbie, working on PSoC 4 to communicate a sensor via SPI. After reading and trying a lot of documents and example, I still cannot make one SPI example work. Without LCD, how could I test an SPI example? To read register of my sensor, I need to select and deselect; write ...
Without LCD, how could I test an SPI example? To read register of my sensor, I need to select and deselect; write one byte address to MOSI, get one dumb byte from MISO, and the write one byte 0x00 to MOSI, the get my data back. I set a GPIO as chip select pin, and connect ...
Hello Team, I am using LPC55S69 EVK, just wanted to check, how can I test SPI interface between two different boards, treating one as master and other as slave? Please provide me few pointers. Regards,San Solved! Go to Solution.0 Kudos Reply ...

If a product allows SPI to be disabled, we will usually also try to test in this condition. What does this all mean? Are these new routers really that slow?! The bottom line is that, no, SPI+NAT routers should not be slower than non-SPI routers in normal use. Here’s why. ...
Here’s how to test failsafe. First of all, remove all propellers for safety. Plug in the battery, turn on the radio and arm the quad, the motors should be spinning at low speed. To simulate a failsafe, you can simply switch off the radio while the quad is still armed. Ideally, you...
First of all, let's do a prior check to make sure that the setup is ready. Make sure your Rasberry PLCs are rightly connected to the power supply. Check that your Raspberry PLC has allthe config files.Check >> Ensure that the SPI is enabled. ...
If we leave it to chance, life with SAP Cloud Platform Integration would be colorless like this:- How do you even work with such an editor in this day and age... let alone test anything on it?? Well, on occasions like this, pardon me, but I would rather take chance into my own ...
