I'm trying to convert 'baremetal' code from the STM32F103 to the STM32G431. I've managed to sort out the GPIO and EXTI stuff, but the ADC is confusing! To start off, what registers on the G4 correspond to CR1 and CR2 on the F1 ADC?

I've spent the last 2 years developing a product using an STM32F103, but I've recently discovered that the ones I've been supplied with are fakes, which have a tendancy to blow up :( It seems as if no genuine F103s are available now, so either I have...

Hi, I'm working on a custom board which I've been programming with an ST-LINK V2 using the SWCLK and SWDIO lines. I mistakenly left BOOT0 floating, but I need to order more boards, so I'm going to correct this mistake.My question: Am I right in think...

I've been working on programming a custom STM32F103 board for a couple of months, using SWD and an ST-LINK V2. For no apparent reason, since 3 days ago, I've been getting the error: "No STM32 target found!" It was literally working fine when I want t...

I ask because I need to test the analogue part of a (custom) board which is powered from 12V, but also generates a 3.3V rail from that. I'd prefer to leave the ST-LINK connected if at all possible.

Thank you for your answer, even if it wasn't what I was hoping to hear :) I've decided to try using CubeMX to generate the ADC initialisation code and see if I can work it out from there.

Regarding ADC1 inputs, you are correct - I didn't notice the other 6 inputs :) In my defence, they're arranged pretty randomly.I'm still debating whether to try redesigning using the G4 or not. One problem is that I can't find any dev boards, so I'd ...

Thank you for your answers. So my problem isn't due to the F1 being discontinued, but 'just' the global chip shortage. (Although, if that's the case, why can't I order F1's directly from ST?)As far as I can tell the F3 isn't any more available than t...

Thank you Peter. Just enough syllables! So it seems I can just route BOOT0 to GND and it should then boot correctly, even if BOOT1 is floating. I'll go ahead and order the PCBs.

Thank you. One of the reasons I'm redoing my design is that the current prototype is bricked and I've been unable to resurrect it. I had the same idea about using tweezers to short the NRST cap, but couldn't get it to work, partly because it's one of...

What registers on the STM32G4 correspond to CR1 and CR2 on the STM32F1 ADC?

What would be a modern equivalent to an STM32F103, preferably in a 48 pin package, and which wouldn't require too many alterations to existing code and PCB?

Confused over correct connections for BOOT0, NRST and SWD.

Error: "No STM32 target found!" on previously-working custom F103 board.

Is it ok to connect an ST-LINK V2 to a board which has a powered 3.3V rail?
