It starts with a 16x2 LCD display and a 4x4 keypad to program, which I physically disconnect and add this parameter (LCDCONbits.LCDEN = 0;). When the main program routine starts, I convert pin of KEYPAD to GND outputs; and keep a DS1307 RTC in the main program routine, I power it with a BC548 transi...

Hello, I tested it using the relay as an indicator at the beginning of the program, and it doesn't restart from the start. It continues after SLEEP, and suddenly, randomly, the current draw rises to 25 mA and remains there until the PIC wakes up 256 seconds later, then drops to 0.020 mA. It consumes...

Hi

Okay, I'll do that test. This way I'll know if it's restarting or continuing where the sequence left off in the programming.

Thanks

Thanks, I appreciate the help.

Hello everyone on the forum, I hope you enjoy a Merry Christmas and a Happy New Year 2026 :!: Continuing with the topic of the SLEEP, WDT, and CLRWDT commands, I'm using a PIC16F1939. It accesses the SLEEP command correctly, although sometimes it doesn't. Previously, I used a PIC16F1847, and SLEEP w...

Hi, I have to say that I prefer a glass of tequila (Agavero), the drawback is that you forget what you were doing. . . . :lol: but in a previous version of Flowcode I had an RTC connected on channel 1 and an LCDI2C display in software, and it compiled correctly, I'm using the same PIC16F1939; but wi...

Hello, I see... I think I'm still asleep !!!!! Thank you very much for the observation, Martin.

I'm using I2C Master for RTC and also LCDI2C Software

Hello,
please could you check the following error that flowcode shows me when compiling, I am using the PIC16F1939.

^ (103) #error: "I2C Channel 2 does not have the SSP2IF defined on this chip - does your chip support this feature?"
