 Forum: General CCS C Discussion Posted: Wed Jun 14, 2017 8:37 am Subject: Interfacing PIC to removable memory |
| I'm using a PIC16F1789.
I'd like to have some type of removal memory storage interfaced with the pic. The type of memory device is not important, as long as I can easily remove it and connect it t ... |

| With Alternate Pin Functions you typically get a choice of two pre-defined
pins for a peripheral function. You have to choose one pin or the other. Example, for CCP1 output, you get to pick Pin B0 ... |

| The 16F1784 does not have Pin Select. It has Alternate Pin Functions.
Thanks. I'm not sure I understand the difference between pin select/alternate pin functions. Is this saying ccp1 can be used ... |

Your first post had ANSEL0 (zero); now changed to ANSELD (Delta). No. I write to both ANCON0, and ANSELD...... I'm almost ready to believe that you're just trolling me?

| Guy is spot on here.
As you change speeds, the CPU power consumption changes, but the peripheral consumption remains the same. Now when you talk about 'displaying the data on an LCD'. What sort o ... |
