So in the code I have separately I'm analyzing the waveform via a logic analyzer. But i am getting the id as 40CE(hex format), but it should be 30DE as to the data sheet. ![]() The connection of the wires according to the library and using the SPI pins modeled on arduino. As the beginner step, I tried to reset the ADC and read the ID register to verify the communication. I have two Arduino (a mega and nano) and two nRF24L01 + to communicate them. I bought the Mega thinking I would be able to carry my SD Card Shield (Seeedstudio 3.0 I believe) to work on my new Mega. I have two Arduinos, an Uno REV2, and the Mega REV3. Typically there is a single 'master' device, which initiates communications and supplies the clock which controls the data transfer rate. I am at the initial stage of the programming part. Hello, Im new to the world of arduino, sorta. The Serial Peripheral Interface Bus (SPI) interface is used for communication between multiple devices over short distances, and at high speed. This library is bundled with every Arduino platform (avr, megaavr, mbed, samd, sam, arc32), so you do not need to install the library separately. To convert and read the values, I'm using AD4114 ADC with arduino mega 2560 as the controller via SPI communication. This library allows you to communicate with SPI devices, with the Arduino as the controller device. Mega 2560 SPI takes place on 50, 51 and 52 as shown below: The current LCD shield uses 8-bit bus interface (LCDD0 LCDD7) instead of SPI. Basically, implementing a battery monitoring system. This can be the hardware SS pin pin 10 (on most Arduino boards) or pin 53 (on the Mega) or another pin specified in the call to SD.begin(). ![]() I am working on a project which suppose to get the digitalized values of current and voltage measurements of a battery module.
