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...
Hellofor some specific usage I am evaluating possibilities of using CM33 with HCLK 250MHz for maximum code execution performance. To do so I have crafted procedure in assembler and calculated the cycles using ARM reference manual. The code is doing o...
Hello,I'm currently working with the STM32F429IIT6 and using the LTDC to continuously output an image via parallel RGB + control signals. The image I'm trying to display is 854x480 pixels in 24-bit RGB888 format. The LTDC clock is running at 10.56 MH...
In 'G0B1, 'G071 and 'L412 Datasheets, ULPEN is mentioned several times (namely 3 times).It probably corresponds to PWR_CR3.ENB_ULP in case of 'G0x and PWR_CR3.ENULP in case of 'L412/'L422.I did not check if this propagates to newer STM32, too.ST, can...
Hi All,I am trying to impliment a frequency shift keying (FSK) routine to represent a each bit of a byte as FSK.My routine is kind of working (see the IRQ for TIM3 below). My FSK is :Bit 0 & Start : 3600Hz Bit 1 & Stop : 1200HzThis ensures that timin...
All,I have somehow concocted a CubeMX configuration (attached) that causes the CPU to latch up when the LTDC clock is enabled during HAL initialization. Here's what I'm seeing/doing:Debugger loads flash, breakpoints at HAL_Init() in main().Set a bre...
