Hi, I have tested the code below with Arduino NANO and TLE5012 using SPI which worked perfectly. What i was trying to read angle.
But i can't make the same code working with ESP32 even trying different SPI initialization.
Can you please help me with the code so that i can have the correct value coming from TLE5012 with ESP32 using SPI ?
Here is the code:
#include <SPI.h>
int angleValue_command = 0x8021; // Register command für Anglevalue read
int ss = 10; //Chipselect pin
void setup()
{
SPI.begin();
SPI.setBitOrder(MSBFIRST);
SPI.setDataMode(SPI_MODE0);
SPI.setClockDivider(SPI_CLOCK_DIV2); // CLOCK speed einstellen 16MHZ/2 -> 8 MHZ
Serial.begin(115200);
pinMode(ss, OUTPUT); //Chip select as output
pinMode(SCK, OUTPUT); //Clock pin as output
pinMode(MISO, INPUT); //Set MISO to input
pinMode(MOSI, OUTPUT); //Set MOSI to output
}
void loop()
{
int miso_data = spi_read(angleValue_command);
if (miso_data < 0) miso_data = abs(miso_data);
// Scale and map the raw angle value to the 0-360 range
int scaledAngle = map(miso_data, 16384, 0, 0, 360);
//int angle = miso_data * (360/(pow(2, 15)));
Serial.println(scaledAngle);
}
int spi_read (int read_command)
{
int data1 = 0;
int data2 = 0;
int safety = 0;
digitalWrite(ss, LOW); // Chipselect auf low
/*------------ Send request to the slave ------------------------
Send 16-bit command */
pinMode(MOSI, OUTPUT);
SPI.transfer((byte)(read_command >> 8)); // 8 High-Bits to the Slave sent
delay(0.2);
SPI.transfer((byte)(read_command & 0x00FF)); // 8 Low-Bits to the Slave sent
pinMode(MOSI, INPUT); // MOSI Pin Switch to high impedance
delay(0.2);
/* ende 16 Bit Commands */
/* 16Bit Data 1 received */
/*-----------------Response from slave----------------------*/
data1 = SPI.transfer(0);
// Für den Fall wenn der Sensor einen 16 Bit Wert zurücksendet ...
data1 <<= 8;
data1 |= SPI.transfer(0);
/* 16Bit Data 2 received */
data2 = SPI.transfer(0); // Response from slave
// In case the sensor sends back a 16 bit value...
data2 <<= 8;
data2 |= SPI.transfer(0);
/* 16Bit safety received */
safety = SPI.transfer(0); // Response from slave
// In case the sensor sends back a 16 bit value...
safety <<= 8;
safety |= SPI.transfer(0);
int miso = data1;
digitalWrite(ss, HIGH); // Chipselect on high
return miso;
}
