Part Number: ADS8332
Hello everyone,
I'm just getting started with the ADS8332. First, I try to read data from a single channel to proof my ADC is working, but even this shows me just the maximum value (65535).
I work with the ESP32 mikrocontroller and got this code so far:
#include <Arduino.h>
#include <SPI.h>
#define SS 5
#define SCLK_Pin 18
#define MOSI 23
#define MISO 19
#define Reset 22
#define CONVST 17
static const int spiClk = 40 * 10^6; //40MHz
int data;
void setup() {
Serial.begin(115200);
pinMode(SS, OUTPUT);
digitalWrite(SS, HIGH);
//pinMode(CONVST, OUTPUT);
//digitalWrite(CONVST, HIGH);
SPISettings(spiClk, MSBFIRST, SPI_MODE2);
SPI.begin(SCLK_Pin, MISO, MOSI, SS);
digitalWrite(SS,LOW);
SPI.transfer16(0xE07D); //0b1110000001111101
Serial.println("Uploaded CFR");
SPI.transfer16(0x7000); //0b0111000000000000
Serial.println("Selected Channel 7");
Serial.println(SPI.transfer16(0XC000)); //try to get CFR back. ->Also don't works
digitalWrite(SS, HIGH);
}
void loop() {
digitalWrite(SS, LOW),
// digitalWrite(CONVST, LOW);
// digitalWrite(CONVST, HIGH);
// SPI.transfer16(0xD000);
// data = SPI.transfer16(0);
data = SPI.transfer16(0xD000);
digitalWrite(SS, HIGH);
Serial.println(data);
delay(1000);
}
The outcommented lines are attempts the get it work.
Thanks in Advance!
