Hello, I want to supply my St Iot discovery kit board with a battery supply, I have changed the header pin to 5V_VBAT. As i am connecting my battery to the Vin and gnd pins the red LED keeps blinking and LD5 is off. Kindly give some suggestions how ...
Hi Developers,I have an STM32L0 microcontroller connected to an NRF24 module via SPI and a SIM808 module via UART. The system is designed to remain in stop mode until an interrupt is triggered by the NRF24 module. Upon interrupt, the microcontroller ...
Hi,I am considering STM32U5 to interface up to 6 PDM microphones. I see that with some STM32U5 version 2 SAIs interface are available. How many PDM microphone can I interface in this case? I found some specific documentation related to G4 (up to 6 m...
Hi all,Reading page 400 of RM0399 (Reference manual STM32H745/755 and STM32H747/757). It talks about how to allocate peripherals for each core. But I don't understand. I can't seem to find the PERxEN bit in either RCC_DnxxxxENR or RCC_C1_DnxxxxENR re...
Hi,I tried to reach 1us delay. To do that I use a timer on 1MHz and try to reach more or less precision delay. void delayMicro(uint16_t delayMc) { __HAL_TIM_SET_COUNTER(&htim16,0); // set the counter value a 0 while (__HAL_TIM_GET_COUNTER(&h...
Hi,I just got a Nucleo 64 with an STM32F466 and want to start developing some own softwareinitialise the MCU for with the maximum clock possibleread 96 kHz stereo SPDIF frames from one of the inputs (polling would be fine)analyse the received data (j...
I've tried both Zephyr RTOS and an STM32CubeIDE HAL project, and cannot get the FDCAN interface to work.After performing requisite initialization steps, I add a packet to the TX FIFO. No error is returned, but no packet is transmitted. I can repeat t...
Hi,some flash operation depends on the MCU supply voltage (see picture).I would like to program an STM32F401 with openOCD, where the MCU is supplied with 2.5V.Is the possible?If yes, - Can I use the stm32f4x.cfg or are there modifications needed?- Sh...
Hi , I am trying to build a simple program for blinking leds in Simulink using STM32 NUCLEO F746ZG. When I push on "Build", Simulink gives me this error. Does anyone know how to fix it? Thank you in advance
Hello there!I have a custom board to control a motor, which I have tested so far using SWD, but now I need it to use the USB DFU to upload new code. As far as I get it, to make the DFU work, I have to put some code in the microcontroller. Following s...
