01_I2C_Test Hardware connection Connect the board to the computer using a USB cable Code analysis app_main(): Firstly, constants and variables related to I2C are defined, such as log tags, the SDA and SCL pins for I2C, and port numbers. ...
NanoS3TinyS3ProS3FeatherS3 RX & TX pins are not coupled with the internal USB, what are they used for? RX & TX are still connected to UART0, and still used with the USB when in CDC (download mode). Otherwise, you can use them as UART0 when connecting a module that uses serial, ...
For the last 12 hours, I've been trying to communicate with an I2C device with no success. The noise gathered by the ADC of the pins with a LRD was unrealistic. For this reason, I ordered a few different I2C sensors to solve the noise problem. I then tried to make a simple sketch...
