Hello everyone,I am kind of new to STM chips, i have a problem regarding programming the chip. I don't use any board, only chip on the SMD to DIP board. But when i want to program it using st-link, STM32cube can identify the programmer but not the ch...
In STM32F405xx STM32F407xx datasheet On page 19/203, there are typos in APB2 and APB1 frequencies.
Hello, I am designing a card that will use an STM32G474QET6TR and I want to program it using USART. The card will use a USB to USART converter (FTDI4232HL). The Rx and Tx of the FTDI are connected to pin PA2 and PA3 respectively, as I found in AN260...
Hi there,I'm designing a custom PCB using the STM32N657Z0 MCU. The design is extremely space-constrained, so I try to leave out everything I can. Since this deviates quite a bit from the reference design (well, the N6 Discovery kit, that is) I'd love...
We are currently using this chip and hope that this selection can be supplied for more than 10 years.May I ask how to retrieve such information?
hi guys, I'm a desktop programmer and do not know much about micro controllers and electronics but i am very interested in making an oscilloscope which:- simple to build with well known parts and ICs- it uses bluepill as the ADC and no other ADCs- i...
Hello all,for my DIY Radio Controller (LoRa and STM32F1C8) i am using two joysticks and one poti.I am reading ADC with the DMA but what i noticed is that the ADC values are not so accurate.I know with not (professional, expensive) Potis and joysticks...
I can't erase the flash in the STM32L552CCT6 with the code below. I wonder if my code is wrong. When I check the memory, the 2kB from the flash address 0x803F800 is not 0xFF. The reason it wasn't 0xFF originally seems to be because something other th...
Hi,We have a 1MEG resistive divider which we hope to provide the reference to the comparator internal to the STM32L073.Though we need to know the input bias current of the comparators inside this micro in order that we can calculate the volt drop by ...
I'm just getting started with my STM32WB15CC nucleo board, and my first goal was to put in shutdown mode to check the current draw, which I expected to be around 1 uA. I'm measuring the current on the JP3 header with a joulescope which should represe...
