reading the battery voltage |
(1/1) |
nspiredev500:
I want to show the battery charge to the user while my program is running, so I have to read it myself. To test it I made a small program that reads the voltages and shows them, but it only works in firebird, not on my CX CAS HW-AA. In firebird it shows: VBATT: 6.0 VSYS: 6.0 B12: 3.0 on my calculator: VBATT: 0.0 VSYS: 4.0 B12: 0.0 Is my program or my calculator broken? Or is only VSYS used in real calculators? Thanks in advance if anyone knows more, I haven't found anything about this. Here is the hackspire entry for the ADC: https://hackspire.org/index.php?title=Memory-mapped_I/O_ports_on_CX#C4000000_-_Analog-to-Digital_Converter_.28ADC.29 EDIT: At 50% my calculator now shows 3V for VSYS, so it really seems only VSYS is used. Would still be nice if someone could confirm this. |

I wish I could help, I just don't know much about the Nspire .___. |
