203 | * aren't allowed to use floating point in the kernel and doing it with |
204 | * integers doesn't provide enough precision. So we'll do boring old |
205 | * look-up table stuff. The unofficial data (see below) have effectively |
206 | * 7-bit resolution (they are rounded to the nearest degree). I'm assuming |
207 | * that the transfer function of the device is monotonic and smooth, so a |
208 | * smooth function fit to the data will allow us to get better precision. |
209 | * I used the 5th-order poly fit described above and solved for |
210 | * VIA register values 0-255. I *10 before rounding, so we get tenth-degree |
211 | * precision. (I could have done all 1024 values for our 10-bit readings, |
212 | * but the function is very linear in the useful range (0-80 deg C), so |
213 | * we'll just use linear interpolation for 10-bit readings.) So, tempLUT |
