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...
Hi everyone,I tried to manage the USAR LIN break detection interrupt using only HAL driver functions but I did not find a way to do that. I had to modify the file stm32f0xx_hal_uasrt.c adding some code to manage the LIN break interrupt.Is there a way...
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...
Is it necessary to enable interrupts in I2C_CR1 if I only want to look at the flags but don't want to go into the interrupt service routine? For instance, I want to be able to look at the status of RXNE and see if it is set, but I don't actually want...
