I read in reference manual and web tutorials of stm32f103c8, there were "AHB", "AHB1" and "AHB2", what's the difference between them, I know "APB1" and "APB2" are 2 APBs, the "1" and "2" are sequential numbers, how about "AHB1" and "AHB2" are they al...

I tried this tutorial on NUCLEO-L412RB-P, it was said "The HAL_EXTIX_IRQHandler and EXTIX_IRQHandler are inside stm32l4xx_it.c file.", I haven't find "EXTIX_IRQHandler" there, is it in somewhere else, or it was needed for L412RB-P?(the tutorial based...

I found in "Figure 11. Memory map" of "Datasheet - production data for STM32F103x8", the address span between Port A and Port B is 1024(0x4001 0c00 - 0x40010800 = 32*32 bits), while I found in "RM0041 - Reference manual STM32F100xx advanced Arm ® -ba...

I have 2 ADC_HandlerTypeDef objects came from 2 different channel of ADC1, and I have an ADC function, like this:ADC_read(ADC_HandlerTypeDef ADC_Handler)How can I use this function for 2 channels?I tried this:if (ADC_Handler == ADC_Handler_1){ .....

And, I found there is a downward arrow under "external reference" block in block diagram on page 3 of DocID1107 Rev 11(L6234 datasheet), and there is also a downward arrow under each drive gate of the 3 down DMOS, are they connected internally?

So what does "external reference" mean? does it mean a reference came from outside or it could be a reference for external components?

I read from datasheet "10 V external reference available", while I tested 8.8v at Vref by a 12v battery source, could I added an external 10v to this pin?

I'm sorry, I haven't expressed clearly. I want to find the solution, so firstly guessed it maybe lack of "EXTIX_IRQHandler", I found it later, and that was not the reason, then I found the solution. Thanks for your suggestion instantly.

I found the reason: the screenshot under"Check GPIO configuration", the item "GPIO Pull-up/Pull-down" should be selected as "Pull-up" for the former item "GPIO mode" selected as "...Falling edge...".
