Hello all,I've designed a board around a STM32H743 (LQFP-100) and am running into the following issue.On 2 boards out of 10, the HSE seems not to start properly. The HSE_RDY flag is never set after enabling HSE. I have checked it's not in bypass mode...
Should each vdd pin of the stm32f407zgt6 read continuity like the blue pill on multimeter, are they internally connected within the chip or separated? Similary for all the vss pins are they also all connected vss inside stm32f407zgt6 Thanks
Hello everyone, I am Li Weiwei (李炜炜) from a company based in Shenzhen, China, specializing in integrated circuit testing equipment and related R&D. We are currently working on a small-scale R&D / prototyping project that requires the STM32F103TBU6 (...
I tried doing an OBD2 request via Car's OBD2 port.I am able to see the CAN BUS traffic using an oscilloscope , just my request frames are rejected by car. I am using STM32h735G-DK development board to send OBD2 requests. It consists of an inbuilt FDC...
There is something strange happening with STM32N657x0HxQ MCU when HAL tick timer is not using SysTick, but a timer like TIM6, and TIMPRE is changed to 4 or 8 while timer is active. Observed it on DK and custom board.I created isolated test code with ...
Hello,Document: RM0090 Reference Manual for STM32F405/415, STM32F407/417, STM32F427/437 andSTM32F429/439.https://www.st.com/resource/en/reference_manual/rm0090-stm32f405415-stm32f407417-stm32f427437-and-stm32f429439-advanced-armbased-32bit-mcus-stmic...
Hi,I'm working on STM32N6 with CubeMX + X‑CUBE‑AI to deploy a neural network model.The first AI model works fine: no compile errors, runs normally.When I replace the neural network model in CubeMX and regenerate code, I get dozens of compile errors (...
Hi everyone,I am currently looking into the STM32F303CCT6 and I'm a bit confused by the ADC specifications. ST's website mentions it can achieve up to 18 MSPS in interleaved mode. However, looking through the Datasheet and the Reference Manual (RM031...
Hello,I am trying to use the I3C interface between STM32H523 and DDR5 SPD. I have found a question would like to be answered: Is there any way to send the broadcase address (7'h7E) with SCL signal configured in I2C timing characteristics?According to...
I'm reading RM0492 Rev 3 about I2C's controller transmitter. The original words on the page of 1185 areWhen RELOAD = 0 and the number of data bytes defined in NBYTES[7:0] is transferred: • In automatic end mode (AUTOEND = 1), a STOP condition is auto...
