When i started using the BIGTREETECH CB1* on the BIGTREETECH E3EZ* i quickly got into the trouble of mapping all the pin descriptions to gpio numbers. Luckily i’m not alone and i found a solution here . The BIGTREETECH CB1 uses a custom IO pinout for the pins which consists of PA, PB….PG and a number. To calculate a GPIO Number, you need to use the following formula: 1 2 [(PG - PA)*32] + {Pin Number} Where PA = 1, PB =2…....
When i started using the BIGTREETECH CB1* i noticed that the system time was almost always wrong. Solution There are different solutions for this but the following one worked the best for me: First remove NTP: 1 sudo apt remove ntp and install the systemd-native timesync service: 1 sudo apt install systemd-timesyncd This should automatically install the service and start it. To make sure, you can check that systemd-timesyncd.service is active (running):...
When i received the BIGTREETECH E3EZ* together with a CB1* i was wondering how the pinout / gpio on the board was setup. Unfortunately the picture in the User-Manual of the E3EZ was relatively blurry. GPIO stands for General-Purpose Input/Output. It refers to the pins on a microcontroller or single-board computer, like the Raspberry Pi, that can be programmed to serve as either inputs or outputs. These pins enable the device to interact with the external world by receiving or transmitting digital signals....
