Hi guys,I need your collective intelligence, because I am a bit lost on the information given by the ST datasheets and reference manuals.Backstory: on a few of our prototypes we started to see random failing behavior and investigated quite a bit. The...
Hello,I need to create an .elf file from a program that I didn't write but has already proven to work. I'm using an STM32L031K6T6 processor and I work with STMCubeIDE. I selected the processor correctly when creating the STM program. The HAL director...
Hi all,I am currently working on a project where an 8 bit bus of 32 MHz is sent to a STM32G474, which has to be saved for 8kB at a time followed by that data being sent over SPI. I have got the SPI part working fine, my question is mainly regarding A...
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...
