Some useful information: RVB2601 development board program download automatic operation and OLED screen protection [Copy link]

 

As a developer, I hate having to press the reset button every time I finish downloading a program to see the effect, so I can configure the CDK development environment to automatically run the program after downloading.

First, right-click on the project name to open the "Option" configuration page, then open the "Flash" tab, check the "Reset and Run" checkbox, and fill in the program start address at the back, as shown below

The next issue is OLED screen protection. In principle, an OLED screen is actually a large number of LED lights arranged together. After a long period of use, the light beads that are lit for a long time will age and dim.

For engineers, it is normal for the development board to be powered on for a long time during debugging, so it is best to dim the brightness of the OLED screen to extend the life of the OLED screen while not displaying images.

As shown in the figure below, the OLED program allows you to set the screen brightness. You only need to change the parameters defined by the macro (I haven't checked the screen manual, so I don't know how to set this parameter for now, but the effect is still there)

Well, even if it is just a starting point, you can share your good experience with me.

Share another resource, when testing the webplayer routine, playing online music,

It may be difficult for you to find a suitable mp3 file, so just use the one provided by Dong. The code is as follows

palyer play http://yocbook.oss-cn-hangzhou.aliyuncs.com/av_repo/alibaba.mp3

The default sound of webplayer is a bit loud. You can modify the code to make it quieter.

The original program defaults to 160. I tried it and found that 32 is a little too low. 64 is a more suitable value. You can test it yourself.
