the address 0x00 is the only unknown address for me. if it is working then, when I tried to follow the User-guide_UM10301 exactly on page 27 where there is an example of how to set the PCF8563: I always get an error in the i2c. my code is as follows: (I use the ESP32 with...

I used the default I2C address for each device; #x70 for the RTC, and #x68 for the display.Setting the timeThe following routine sets the time:(defun set (hr min) (with-i2c (str #x68) (write-byte 0 str) (write-byte 0 str) (write-byte min str) (write-byte hr str)))...
Adding additional sensors to the I2C bus is extremely simple, as long as each sensor is programmed first to a different address and the bus capacitance is low enough for the pull-up resistors to work properly. GND, V+, SCL and SDA simply need to be connected to the existing wires that ...
The digitally configurable approach enable customers for predictive maintenance in sophisticated industrial systems. For example, 1ED38xx is able to register the counts of UVLO spikes, monitor the supply voltage and temperature increase. With the long-term analysis of the collected data, customers are...
