thanks BenR I have tested the SPI modification and I would say that it works, but I think I will go back to the old and loved mega2560 because it seems to me that the rpy pico is not yet well developed and many other things do not work, I would be tempted to try with the blackpill that mounts STM32F...

hello BenR
I am sending you part of the project
thank you

hi team
I have a problem with the SPI component, using it with RPI PICO the compiler gives an error, the component had been changed recently the prescaler frequency setting I am attaching the compiler files
thank you

ok, sorry now I understand
thank you

Hi Martin I did this test by reading your advice, I added an I2C component and then I went to write the bit 1 to 1 on register 0X0E to enable alarm 2 and now I see the impulses that activate and deactivate the LED every minute, I have turned off and turned on several times (without backup battery) a...

Hi Martin
I added the UART and from the video you see that the time runs regularly, at the end of the minute on the LED L there is no change of state, I also added a RestartRTC but it has no effect

Hi Martin I tried your program but the led does not show signs of life, the only things I changed are the LED port because on my nano there is already an LED on B5 and I feed the DS with the 3.3V coming out of the board, if I disconnect pin interrupt 1 (D3) the LED flashes very quickly so as long as...

Hi Martin
I have an arduino nano available, today I will try your program
thank you

hello mnfisher yesterday I saw your post and I picked up the ds3231 again and on ESP32 it started working (at the stroke of the minute I saw the ESP32 output lower and then return to high and this happened every minute) I was happy but confused because it was a while I got nothing out of the way, an...

Hello everyone I was able to test the RTC ds3231 component on RPI Pico but the alarms do not work while the reading and writing of the time and date work, the strange thing is that it no longer works even on ESP32, the output always remains at 0, if I do not have wrong should bring to 1 at the end o...
