Hi,
with the PCF8574 and 8575 everything works wonderfully. I'll get this chip.
Thanks

Hi medelc35 I've looked over my hardware again, but I can't find anything strange. I even removed the MCP23017 board and connected it to another BlackPill STM32F411, but it didn't work. I replicated the same code for an Arduino Nano, but it didn't work either. I also replaced the MCP23017 board with...

Hi, I'm referring to a previous post of mine regarding interrupts on the MCP23017 component https://www.flowcode.co.uk/forums/viewtopic.php?t=3107. With the help of Medelec35, the component worked, but now it doesn't. Have there been any updates that have compromised its functionality? Can someone t...

Hi,
I tried inserting the suggested 125mS delay for 8-sample sampling and added a very crude RDY pin handler. I'll ask mm-fisher if this is correct or if he suggests something more suitable. Testing on two channels seems to work well.

THANKS stefan.erni
Setting it to 860 works. One question: I'm not using the ALLERT/RDY pin right now, so can it be ignored?

Hi, I tried your suggestions. I reset it to 400kHz, sampled at 64, then went down to 16 and 8. I increased the baud rate to the maximum, set it to continuous mode, and I actually initially set the IRQ rollover value to 15600 to get 1 second. I don't know why it reverted to 65536. The values ​​for ch...

Hi,
1) I've already tried continuous mode with no results.
2) I've already tried 400kHz. I'll try sampling rate adjustment later.
3) Why 0.25Hz?
Thanx

Hi, I'm testing the ADS1115 component and I've noticed some strange behavior. Basically, in the code, if I select only channel A0 on the UART output, which I read with a serial program, I read the correct value as ch1. The same thing happens if I select only A1, excluding A0 from the program, I corr...

Hi, thanks everyone for your support. I've always used Dropbox. The files are in a folder on my PC and then updated on Dropbox, and it's never given me any problems. I put the LED file in another folder on C, but I get the same error. Now I've downloaded FC10 to a laptop connected to Dropbox, and th...

ok sorry
the files are attached
thank
