I am recently working on USB CDC in STM32F407 and i have the following doubts:Based on my understanding 64 bytes can be send using CDC_Transmit_FS, so can we give a array of some size which is greater than 2KBytes and DO we need to do any chunking h...
Hello, I spend a lot of time to tried running HW SPI on H523CET6. On the other mcu like F411 it work without any problems. In this case SPI work only when I do it in software mode://===================================================================...
I configured SYSCLK to 480 MHz and set the I2C1 peripheral clock frequency to 120 MHz. For I2C1's timing settings, I selected Fast Mode Plus (1 MHz) and applied the timing register value 0x0050174F, the setting about maximum output speed of SDA and S...
Hi all,I’m working with an STM32H745 controller and an external ULPI PHY (FUSB2805, pin-compatible with STULPI01A). All hardware connections are verified and correct – the PCB layout and power rails are within spec, and the ULPI lines are as per the ...
Dear friends, I am playing around with NUCLEO-H745ZI-Q.I generated example motor control project from en.X-CUBE-MCSDK-FUL_6.4.0 for CubeIDE v.1.18.1. This example project utilizes CM4 core. Clock frequency for CM7 core can be twice higher than the cl...
Hi all,I'm designing STM32N655L0 based board and I've one question.I'm using XSPI1 and XSPI 2 peripherals.XSPI2->Octa SPI mode, NOR FlashXSPI1-> SDRAM, Hexa SPISo my question is can I use unused CS, NCLK pins as an IO?I just wanted to be sure. BR
Hi,I want to increase the amount of RAM for my application, but I noticed that the NPU seems to be using memory from address 0x34100000 (SRAM2) in the sample application it is based on. Where can I change this? Are there any limitations to the memory...
Hello,the following code is generated by CubeMX 6.11.1 in module stm32l4xx_it.c:/** * @brief This function handles TIM1 trigger and commutation interrupts and TIM17 global interrupt. */ void TIM1_TRG_COM_TIM17_IRQHandler(void) { /* USER CODE BE...
Hello,I was looking into this wiki tutorial on setting up a UDP echo server by @mƎALLEm , and the clock configuration caught my eye and wanted to confirm a few things.On the nucleo board , the 8 MHz crystal (X3) is not soldered and the 8 MHz clock si...
I am using a STM32H723ZGT6. I am trying to Trigger an Input Capture on TIM1 Channel 1 by connecting to the output of the Comparator internally,but cannot get the TIM1 Configuration to fire the Input Capture Callback. I've turned on the input capture ...
