VoCore: Power Save Test => Turn off WIFI + Ethernet

Just want to know, in standby mode, how much power will VoCore consume. It is very interesting, if we shutdown ethernet, VoCore current consume will low to 0.1A(0.5watt), if we shut down wifi, how much power will it consume? First, call script http://vonger.cn/?p=1880, shutdown the ethernet. Then, power off wifi.(add “option disabled 1” to /etc/config/wireless) […]

VoCore: Save Some Power(1.0w => 0.6watt)

Some users are asking about save power on VoCore, it is easy to do. 1. Download this simple tool: mems(or compile mmio) 2. scp this mems to VoCore. 3. make it executable. chmod +x mems 4. call the following command to save power by shutting down ethernet 0~3. ./mems 0x101100c0 0x08002000 ./mems 0x101100c0 0x08002001 ./mems […]

VoCore: AP+STA Power Consume

This is my first time to record a video for VoCore,  some parts are not very clear, next time will be better 🙂 +5V input, current is about 0.2A when wifi is on. I did not use any power save kernel module or app, amazing! I thought it should be at least 0.25A. :p Its power consume is […]

VoCore2: PoE upgrade

Current VoCore2 PoE version is based on MAX5987AETE, which has become too expensive and can no longer be afforded. Since last year, we have been searching for a new solution, but finding one with low power consumption and smaller size has proven to be difficult. After considering various options, the best balance solution for VoCore2 […]

Screen: MPRO firmware hotfix 3

Recently some MPRO samples had reported random disconnect sometimes or can not detect at all. After some investigation and testing, it is confirmed that it is not a software issue, but two possible problems, which are highly related to USB cables and PC USB voltage leak. The first problem is normally caused by the USB […]

Screen: 5inch Upgrade to MPRO

After one and half years develop, finally the big upgrade for screen driver comes. This new driver board named MPRO, it has many notable new features. Startup LOGO 60FPS at partily draw, 33FPS at full draw(5inch). Partily draw mode. I2C external device(for LEDs and buttons). USB Type-C connection More current for screen backlight. OLED, round […]

VoCore2: TeraTerm fix brick

For Windows user, a good kermit terminal is not easy to find, we suggest to use TeraTerm. TeraTerm download link: https://github.com/TeraTermProject/osdn-download/releases Reference to vocore.io/v2.html or vocore.io/v2u.html, we use TTL to upgrade firmware if the uboot is still alive. Hardware part, need to connect USB2TTL device RX and TX to VoCore2 TXD2 and RXD2, then we […]

Screen: Dashboard Solution

Because Simhub makes it very easy to DIY a dashboard for sim racers, many people ask about tech support for DIY projects with VoCore screens. This tutorial will help you choose the parts. To complete a dashboard, the easiest way is to use existing solutions. The most common one is to use Arduino to control […]

VoCore2: Boot from memory/USB

Sometimes we need to do some test fast, or test new system like ECOS, so maybe boot from flash is not a good idea, it is slow to write and load. Then maybe good idea is boot from memory. First, enable ramdisk from openwrt menuconfig, this is default enabled normally. If not, it is at […]

VoCore2 Super: Combine Ultimate/PoE

This version I planed a long time, but because it is super hard, tried many times all failed. I faced many problems: PoE voltage is 50V~60V but VoCore2 is only 5V, how to protect VoCore2 from outside noise or unexpect high voltage(like lighting from ethernet)? PoE heat is pretty much, VoCore2 Ultimate already very small, […]
