I need to contact the ADC via arduino nano on the SPI bus and get a response. I can send a byte, but I can't get a response. The hardware SPI did not work, I decided to write a software one, maybe I'm reading the port incorrectly? The output is just zeros. #define rStatADC 0x10 #define rDataADC 0x1…

[image] volkodav215: I need to contact the ADC via arduino nano on the SPI bus Please clarify, what do you try to achieve? Contact ADC port via SPI?

what ADC are you using? provide a link to the datasheet ?

Hi, Can you please provide in a new post; Link to specs/data of ADC. Schematic of your project. Thanks.. Tom... :smiley: :+1: :coffee: :australia:

Yes, ADC AD7730, The clock and writing work for me, reading does not work, I send bytes to the register, but I can’t read, apparently the read function is implemented incorrectly. But I don't know how else to make the program read the data sent to the ADC. In this example, I am trying to read regist…

Hi, @volkodav215 This may help from another post in the forum [image] Arduino and the AD7730 Science and Measurement Hello this is a brief post to help as an example of a working AD7730 project, I was unable to find any fully functioning code for the AD7730 and arduino s…

If I knew a lot, I would know what to do and would not ask. For the first time I hear that there are many different arduino nanos, and what does it make sense here? It is the code that does not work, the reading function is unsigned char SPI_read (), maybe I am accessing the port incorrectly, trying…

This line will be transfer the byte inverted: [image] volkodav215: if (Byte & 0x80) digitalWrite(spi_di, LOW); else digitalWrite(spi_di, HIGH); // выставляем один бит Your read function doesn't looks correct too. Where do you find this code? Why you don't use the hardware SPI ?
