Part Number: ADS1231 Hello, I don't understand what is going wrong. When the data line is ready I read 24 bits, but the value is always the same: 0x800000. I enable AVDD voltage, wait 2 seconds to make sure voltage is okay, and wait 15useconds between measure and measure because od the update time. Why am I getting this value?? This is my code: void ads1231 _on() { DO_PIN_AVDD = 1; // Enable AVDD DO_PIN_ADS_PDWN = 0; __delay_ms(2000); DO_PIN_ADS_PDWN = 1; // Enable ADS1231 DO_PIN_ADS_CLOCK = 0; } void ads1231 _off() { DO_PIN_AVDD = 0; DO_PIN_ADS_PDWN = 0; } int24_t ads1231 _read() { int24_t data = 0; int24_t tmp = 0; int8_t bit_shift; // Wait the IC to be ready while( (DI_PIN_ADS_DATA)==1 ){}; __delay_us(100); // Read data for(bit_shift=23; bit_shift >= 0; bit_shift--) { DO_PIN_ADS_CLOCK = 1; __delay_ns(200); tmp = DI_PIN_ADS_DATA; tmp = (tmp << bit_shift); data |= tmp; DO_PIN_ADS_CLOCK = 0; __delay_ns(200); } // Send Final clock signal to end transmition DO_PIN_ADS_CLOCK = 1; __delay_ns(200); DO_PIN_ADS_CLOCK = 0; __delay_ns(200); return data; } void main(void) { setup(); // Setup IO int24_t value1; int24_t value2; int24_t value3; int24_t value4; int24_t value5; int24_t value6; int24_t value7; ads1231 _on(); while(1) { value1 = ads1231 _read(); __delay_us(15); value2 = ads1231 _read(); __delay_us(15); value3 = ads1231 _read(); __delay_us(15); value4 = ads1231 _read(); __delay_us(15); value5 = ads1231 _read(); __delay_us(15); value6 = ads1231 _read(); __delay_us(15); value7 = ads1231 _read(); __delay_us(15); } } Thank you!
