Hi, I'm trying to write i2c ISR by myself with LL. But after START condition address don't transfer(I see it in my oscilloscope), although I write to I2C1->DR address of slave and read reference manual with attention for proper handling.I generate in...
Hi,I prototype the use the USB virtual com port on a STM32F407 Discovery board andit worked without any problem. I then repeated the exercise on our custom board(STM32L4P5VGT6), the first stage was just transmitting it worked without aproblem. Now ad...
I am working with several STM32, let's focus on the STM32L4P5. I wrote a windows utility which does a nice job of loading code with the bootloader, per the AN3155 documentation. It is nicely robust, and I've been using it for a couple months. I wan...
Hello,I'm working on a NucleoF746ZG, for the past week i'm unable to communicate with board tought UART.The problem seems to be that HAL_UART_Init(&huartX) return 0 which means that the UART is not initialized.I tried to check if it was a hardware pr...
I have an ADC+DMA read that can performs at 4Mbytes/second.The conv is 12 bit, clock division is 1_of5. On the callback DMS interruptsI send half data's to USB using CDC_Transmit_HS. The ADC buffer is 1K. I Also tried 2, 4, 8, 16k. I played with the ...
Hello,We are designing a board with an STM32H7B0VBT6 and USB3320 USB HS-transceiver. The MCU will run at VDD=1.8V. In AN5307, p. 11 it is written:"On some packages neither the VDD33USB pin, nor the VDD50USB pin are available, it is the VDD pin which ...
Has anyone been able to convert a TouchGFX project from FreeRTOS to Azure RTOS by simply using the freeRTOS compatiblity module provided, then changing the oswrapper files to use non-CMSIS calls (pure FreeRTOS API) and no other changes? This would b...
Hello all. If I create a threadX build for say STM32L496QGI3Will I be able to use the same build in the entire STM32 line? Or just SMT32L's ?At what point do I need to build again?thanks
Hi,I'm trying to understand the purpose of CDC_RNDIS_Itf_Process in usbd_cdc_rndis_if_template.c. The @brief for this function is the same as CDC_RNDIS_Itf_Receive function, which I think is incorrect. I can't find any calls to this function ( USB_CD...
I can invoke the ROM bootloader on the STM32U575ZI both by pulling PH3 to 3v3 at boot and I can then connect STM32CubeProgrammer using USART1 PA9, PA10 as described in AN2606. However the STM32U5 does not enumerate via the USB-C connector on the Nucl...
