So where exactly does the documentation say that different FIFOs can't be accessed simultaneously?In dervice mode, an In endpoint was configured to transmit one 16-byte-long packet, and then 16 bytes (i.e. 4 words, 72 43 70 A4 D9 99 55 2E 19 7F 32 37...
Working with LWIP using TCP echo example code on STM32H743I_Eval and CMX V1.3.0.After receiving a packet and extracting the payload netbuf_delete(buf) gets called which works most of the time. When it does not work it throws an assert failure in pbu...
Can we run real-time Linux on the STM32F7 series (particularly STM32F777II)?What all real-time Linux versions are available in the market today that can be chosen?What benefits does real-time linux will bring in on the MCU as compared to going for a ...
Posted on September 25, 2014 at 08:45Hello! I'm using the USB CDC class implementation provided by STM32CubeMX 4.3.0 (firmware library v1.3.0). Is it possible to check on the microcontroller if the virtual COM port has been opened? I want to transmi...
Posted on January 26, 2018 at 16:55Hi there,we are currently developing the firmware for our custom board with an STM32F746 MCU in LQFP-100 package. Our current version is working well and now we want to be able to download updates via USB DFU. I re...
Hello! We use a chip in our product and connect it via USB, so we need VID:PID. STM can give VID as a free service. I opened a case in the tracker, but there is no answer for 3 weeks. Who can I contact on this issue?1. COMPANY NAME AUTHORZING USE TO:...
I'm trying to make work USB_HS peripheral (External PHY is USB3320). I configured CUBE project, generate code, pass 24 Mhz to USB3320 and there is nothing. Even pull up resistor that should indicate new USB device isn't working.MCU: STM32H743IIT6 mxC...
I'm tring to set up an HID on a NUCLEO-STM32H743ZI. My demo code is very simple:uint8_t buffer[8] = { 1, 0, 0, 0x04, 0, 0, 0, 0 }; while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ if (HAL_GPIO_ReadPin(GPIOC, GPIO_PIN_13) == GPIO_PIN...
Hi All, We are using STM32F746 MCU with external Memory. We use internal flash for bootloader image and our main image is on QSPI memory. We read something about STM32F7 HW issues for example to access QSPI using DMA, Cache's need to be disabled. On ...
I've got a problem with stm32f407zet . I use also LL drivers and 3 ADCs with dma .No problem when run separately , e.g. only ADC 1 - results are corrects , only ADC3 - results are corrects .Problem is when I turn on two ADC by ://adc1 LL_ADC_C...
