Resolved! Distinguish between PA and PB external interrupts
I am trying to understand the external interrupts for the STM32F103C8. It seems that I can attach an interrupt to any of the PA or PB pins. The first 5 pins (0-4) seem to have unique IRQ handlers, whereas pins 5-9 share a handler as does 10-13. When ...
STM32F407 HAL_UARTEx_ReceiveToIdle() function missing
Hello. I am working on a project where i need to get different lenghts of data using UART and preferebly with least possible amount of iterrupts, so ive settled to using HAL_UARTEx_ReceiveToIdle() function (when testing the project on F103), but when...
STM32L0xx - why is PA4 initialized as digital input?
In STM32L0xx, all pins are initialized as Analog, except PA13/PA14 which are SWDIO/SWCLK, initialized as AF; and PA4, which is initialized as [digital] Input.I can't find any reason for the latter.It's not that important, and I can simply take it as ...
OTA update
I would like to know if the following is possible and if so, where can I find information about it.I have a STM32L010K8 micro connected via USART to an LTE CHIP (BG96) through which I can get the firmware update that runs on the microcontroller. I co...
STM32F3 - Permissible Magnetic Field Strength
I am currently using the STM32F3 series microcontroller (STM32F303CB) in a magnetic sensing application. Since the environment is prone to magnetic field, I wish to know the maximum field strength that the microcontroller can withstand.I could not fi...
Resolved! How to get the audio line-in data from the STM32H735G-DK?
I tried the BSP example for H735G-DK, but it doesn't work.What I want to do is get an audio wave from line_in (the blue audio jack on the board).The setup for SAI1 is in the picture, I can play the audio through the line out without any problem but c...
interface MAX1300 ADC with STM32F0 DISCOVERY through SPI
Hello,i am trying to interface MAX1300 ADC with STM32F0 DISCOVERY through SPI but not able to receive complete 16bit converted data.8-bit of data is not getting received through spi. suggest some solution to resolve this issue
Resolved! Why are missing features still present in DS? Answer: It only pertains to an old revision of the chip.
yet and of course also in the pins table. Why??OK I take it back - this is pertinent only to rev.A of the chip; there are newer revisions where this (and other rather disturbing errata) is already fixed.JW
Can't run application with my Nucleo-144
The Nucleo is H743ZI2 (Nucleo-144).I can properly update the firmware so I guess the Nucleo is properly detected by STM32CubeIDE.I can properly build the application without errors.However, I can't run it. For some reason, the board is not detected a...
