11 years ago This does indeed fix the problem. What a stupid mistake. I will try to fold this change it tonight.

This solves it:
INT8U io_read(RegisterID_e reg, REG_u *val) {
ifdef USE_I2C
return(i2c_read(as3935_addr, reg, val));
endif
ifdef USE_SPI
INT8U c;
/* Enable chip select */ digitalWrite(SS_PIN, LOW);
/* Write register address */ c = SPI.transfer(((INT8U)reg&0x3f) | 0x40);
/* Read value */ c = SPI.transfer(0x00);
/* Disable chip select */ digitalWrite(SS_PIN, HIGH);
val->data = c;
return(0);
endif
}
INT8U io_write(RegisterID_e reg, REG_u val) {
ifdef USE_I2C
return(i2c_write(as3935_addr, reg, val));
endif
ifdef USE_SPI
/* Enable chip select */ digitalWrite(SS_PIN, LOW);
/* Write register address with read bit set */ SPI.transfer((INT8U)reg & 0x3f);
/* write value */ SPI.transfer(val.data);
/* Disable chip select */ digitalWrite(SS_PIN, HIGH);
return 0;
endif
}
