Hi! I am working on a project in which I'd like to use an stm32U0 MCU. It'll be my first time with one of these, and I'm choosing it because my design includes a battery (+charger & fuel gauge), so I'm interested in learning about low-power things. I...
Hello,I have problem statement, in which I have to re-Initialize lptimer for different timer value, as per current scenario, I haveClock: 32Khz (LSI)Divisor = 128Period: Any time as per dynamic input. So I want information about how I can safely rese...
I am using the OCTSPI1 of STM32L4Q5CGTX to set HYPERRAM to memory-mapped mode.Memory can be read and written correctly.When I use STM32CubeIDE to check the HYPERBUS signals with an oscilloscope while the CPU is stopped with a break during program exe...
Hi, I was trying to implement timer interrupt on an ST32F407 Discovery board. The ST-Link on my board has been broken so I used an external ST-Link dongle and I have it connected by following this post:https://electronics.stackexchange.com/questions/...
I want to measure ADC on multiple pins. I don't need DMA, just measure PA0 then measure PA2. Measuring PA0 works, but when I switch the channel to 2 it still measures from PA0:In my main loop I do this: // Configure channel ADC_ChannelConfTypeDef s...
Hello, I was wondering about the reasons to supply external clocks to the N6 MCU, since it seems that via HSI and LSI there are clocks integrated into the MCU. I am having trouble to understand whether the internal clocks can satisfy my requirements:...
Board & Setup: STM32H563RGT6 running FDCAN2 in Normal mode (HAL_FDCAN_Init, Mode=FDCAN_MODE_NORMAL) SN65HVD230 transceiver in silent mode (Rs pin connected to 3.3V) (120 Ω intergrated) wired with a single 120 Ω terminator at the far end No other p...
Test procedure.Nucleo-H753zi with "arduino style" shield installed.Hardware includes DAC80501 to generate linear ramp 512 points, than OP amp to scale up and convert SE to Diff.ADC2 runs in Diff mode, channel 3 (PA.6 & PA.7 -> SB 33/ 35 modified),clo...
Hello, I have been trying to implement USB support on an STM32u5g9vjt6Q using USBX in standalone mode without success as of yet. I have been referencing this guide (How to implement USBX in standalone mode ) I am trying to use the onboard USB Phy in ...
Hello Everyone,I'm using a Nucleo-G474RE board with TIM20 configured in input capture mode on channels 1–3 to measure PWM frequency from a function generator. Everything works fine when the signal is active, but when I turn off or disconnect the inpu...
