There will be a few other registers of interest, but we’ll return to those later. For now, note that the time and date start from 0x02. And one more thing – data is stored in the BCD (binary-coded- decimal) format. But don’t panic, we have a couple of functions to convert n...

To fix this, use a logic shifter chip that converts between 3.3V and 5V logic. This library has been successfully tested on many boards including: ESP32; STM32; Mega 2560; DUE; ATmega328 and Atmega32u4 based boards; ATtiny85, Raspberry Pi Pico (RP2040) and more. See Boards where this...
What is "bit"? Most of mathematics calculations are done in decimal, where one means ten units of the next smaller digit. However in computers, we use binary, where one means two units of the next smaller digit. The analog output signal is 8 bits, that is, 2 8 = 256; and the init...
every single day till it was finally giving nice output ( I think) ... Regarding the 24 bit .. I just followed the datasheet and applied the other four clocks to force the output pin of the ADS1230 to be high and that what I am getting .. but I only convert 20 bits of it......
double toDouble(void)convert value to double or float (if the same e.g. UNO). float toFloat(void)convert value to float. String toString(unsigned int decimals = 2)convert value to a String with decimals. Please note that the accuracy is only 3-4 digits for the whole number so use ...
That should get you started printing text and the decimal value of integers. SeeRecipe 4.2for more detail on print formatting options. You may want to consider a third-party terminal program that has more features than Serial Monitor. Displaying data in text or binary format (or both), displa...
An easy way to determine the hexadecimal value to control the LEDs is simple, image you have one row of LEDs – the first eight being green and the second eight being red. Set each digit to 1 for on and 0 for off. The convert the two binary numbers to hexadecimal and use this funct...
