Hello community, I have this difficult task of powering an STM32G0B1 from a pin that was really not tasked for that (because the connector I have to plug onto provides no supply pin). In short, I can't draw more than 500µA current at any time or I ri...

Hello,New to this forum and quite new to STM32 platform, so hi to the community! I have trouble setting up comparator on board nucleo-stm32G0b1RE. I've been following some tutorials on how to setup through stm32CubeMx, I believe I have the settings r...

Hello again,After some trials, I was able to boot my MCU, thanks in part to larger capas, although I wasn't able to solve the initial 30ms power spike. I believe it is the "reset state" that just takes 30ms, because when I push the reset button, I ge...

Oh yes, indeed. I'm so used to having cubeMX doing it for me that I forget when I need to set it up manually.

Hello,I tried to set low power mode as soon as possible, just after reset, but I see no improvement to current peak duration when I power up processor @TDK .Here is my code modification. Debugging tells me I go through the code allright before going ...

Thanks for your reply @TDK . It is as I feared...Although 1ms instead of 30ms might be enough for capas to fill the necessary current.Where would you change the reset handler? I have no experience with that so far...Restoring the changes after each r...

That's the solution we are trying right now. But because it's a pin we are highjacking that is used for another purpose, we must first delay input, set MCU behind a delayed mosfet and so far, the large capa doesn't play nice with mosfet (smaller ones...
