How to connect STM32H745I-DISCO with openOCD using openOCD ?
Hello,I am not able to connect my ubuntu 20.04 laptop to a STM32H745I-DISCO board using openocd.```$ openocd -f board/stm32h745i-disco.cfgOpen On-Chip Debugger 0.11.0+dev-00450-ge67ff42de (2022-01-14-09:58)Licensed under GNU GPL v2For bug reports, re...
Reading unavailable pin.
Hi,I have a program that will run on STM32G030C8 or STM32G030K8. C8 has a 48pin case, K8 - 32pin. The PC13 port is available in C8, there is no output in K8. If I read this pin in K8, it always returns 0, regardless of whether I turn on the pullup. W...
Resolved! How to clear internal SPI TX buffer in slave mode after transaction cancellation? SPI used in slave mode with DMA circular buffer.
Hello. I am using STM32F407VG controller. I have to transfer data from another device via SPI interface. STM32 SPI is used in slave mode, circular DMA enabled. Devices are connected via joint.In some cases I need to resynchronize data exchange. At th...
Resolved! Strange Issue with startup_stm32f072xb.s and stm32f0xx_it.c order?
Hello,I have a strange issue!, so my project is using cmake to build and it is in c++. Everything is working if i set the startup script (startup_stm32f072xb.s) before stm32f0xx_it.c But if i set it after stm32f0xx_it.c, than nothing happens it is li...
Is it possible to synchronise the four I2S FS outputs in master mode on an H7B0 device ?
I need to have the four I2S inputs on the H7B0 device synchronised so that they all sample the ADCs at exactly the same time. One method is to run the I2S modules in slave mode and input an external FS and CK to all four I2S and to the ADCs, but it w...
STM32 F0 SPI slave proper setup
Hello there,So far I was designing only SPI masters in the STM32 MCU's- now I am doing a slave application and I am having problems. First of, I was surprised that the STM32CubeF0-master repository doesn't consist of a single SPI slave example (pleas...
Hello I am using STM32F746 discovery board and trying to transfer data in PCM format using I2S protocol provided
HelloI am using STM32F746 discovery board and trying to transfer data in PCM format using I2S protocol provided. I have configured for below mentioned settings hi2s2.Instance = SPI2; hi2s2.Init.Mode = I2S_MODE_MASTER_TX; hi2s2.Init.Standard = I2S_ST...
Resolved! Is it possible to trigger a GPIO pin by an RTC alarm in VBAT mode only?
Hello ST Community,In my application I want to pull up a Battery Latch Pin for a short time in VBAT mode using the integrated RTC Alarm Events.Based on the datasheet of the STM32F722xx STM32F723xx it is described that:When the microcontroller is supp...
Is it possible to give external reference voltage to STM32L431RCT6 microcontroller ?
I tried to give external reference voltage to STM32L431RCT6 microcontroller using precision voltage reference IC. But the controller is not taking any external reference voltage. Is it possible to give external reference voltage to STM32L431RCT6 micr...
