I thought about it and I don't know if it can have a practical effect in some application, from the datasheet I saw that INTA and INTB can be combined, so maybe you can use a single micro pin for the interrupt

thanks for the component modification, the ConfigureIOC and ReadINTFlag functions work on portA, on portB I couldn't test them because I don't have a ready HW, but if you want I'll set up something quick to try

HI, if it can be useful to someone I managed to activate the INTA interrupt by modifying the GPINTENA register at address 0x04, inserting 255 modifies all 8 inputs of portA, (verified and it works) if you also need it on portB you have to modify GPINTENB at address 0x05 (I haven't tried this yet), I...

Ok thanks Martin it works I was misled by the description of the parameter that indicates 0 or 1, I take this opportunity to ask you another question about the component and precisely about the use of INTA and INTB that in the idle state are in the HIGH state to switch to the LOW state when the 2301...

HI, I'm trying an MCP23017 to expand the inputs, I noticed that when I use the ConfigureInversion function only A0 inverts the logical state from HIGH to LOW, to do some tests I only connected the first 4 inputs, as Hardware everything seems fine the inputs are all HIGH and when I close the contacts...

OK done, thanks

HI I made a small code to test the analog inputs on the blackpill board that mounts a STM32F411RET using FC10, but during compilation I have many errors, I replicated the same code on FC9 which compiles correctly and the code on STM32 works correctly, I attach the 2 codes and error report of the FC1...

since in many battery-powered IOT systems attention is paid to energy consumption, could you implement the sleep and stand-by functions of the various micros in the components?
thanks

Hi everyone, I wanted to ask if with the internal RTC of the stm32f411 it was possible to wake up the micro from sleep or standby conditions for example every 5 minutes, if so how can it be done?
tank's to all

ok thanks, I just saw your answer now, when I have some time I'll try
thanks
