Hello.
When I read the serial number of a DS18B20, it outputs a 12-digit string.
I'd like to convert this to a ULONG variable.
Is there a quick and easy way to do this?
Thank you.

ADS1115 I2c Read trouble
Hello. I have a question. I'm reading nine analog values using three ADS1115s. The ADS1115 inputs are connected correctly and the voltage output is accurate. I'm reading them using I2C, but the values aren't being written to the correct variables. I've tried reading them using both the voltage and r...

Re: Question about communication between two mcu via spi
When I send each variable to serial, the data does not come out correctly.
The order of each variable is .
123 124 125 126 127 128
This is the order in which the values of the variables are printed.
128 123 124 125 126 127
Thank you.

Re: Question about communication between two mcu via spi
One piece of data is read successfully.
However, the second piece of data is displayed as the requested local address.
Any other ideas?

Question about communication between two mcu via spi[Solved]
Hello.
I want to communicate between MCUs (PIC24FJ512GA606, PIC18F45K40) via SPI.
I tried following the examples, but communication isn't working.
There are 12 data items.
If you could provide a simple example, I'll try to implement it.
Thank you.

Ultra High Speed Data Acquisition mathod need advice!!
Hello? I have a question. I am trying to make a device that generates 16-bit analog data about 120,000 times per second, and the data is generated for about 2.5 seconds. I want to transfer the data generated here to a PC using MicroSD memory or serial communication. To store the data, I think I need...
