Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hi,I have a few questions about how the STM32 works.I would like to be able to jump from my main program to a secondary program (bootloader) That will carry out a firmware update if one is available.My plan here is to have my main application running...
Hi,I would like to use USB HOST to use multiple devices. We would like use the following configuration :1 host and 15 devices max with 5 hub between themSo I am using STM32H747 as Host and I saw the following sentence in Reference manual :"Up to 16 h...
Hello,I am trying to use the USB HS interface of the STM32F730Z8 but I can't get it to work. I am doing this on a PCB I designed.I am using the latest version of STM32CubeIDE and I configured the interface with the CubeMX integrated in the IDE. I sel...
Hi,I'm trying to get the dual bank image swap feature of the STM32G4 to work, so far without success.I tried first on my own board by following the (very sparse) information in the reference manual. However every time I set the BFB2 bit in software a...
Hi Sir , I have set a project using CAN .Now I have found a problem , the max value is 0x80 ,in the datasheet it can be up to 255.Please help me to find why ,the following is my configurition code:void CanInit(uint32_t gateID){ //CAN1_Mode_Ini...

We are trying to Rx Bulk short packet (max packet size 4 bytes) at high speed and with low software load by using the USB HOST core of OTG_FS IP mounted on STM32L476.Prerequisite condition・I don't use the code generated by cubemx.・Host and Device co...
Previously, I use STM32F205 (M3) USB HID, out endpoint (Interrupt type).Now I'm developing ST M0 (STM32F070) and I have a problem as followBy using STM32F070, HID USB, and then enpoint 5, Out Interrupt should be use. But, Device send only STALL pa...
I am sending an RTR message to two different micro controllers. On an F412 an RTR value "2" arrives, on an L471 an RTR value "1" arrives.When looking at the code in f4xx_hal_can.c from the STM32Cube FW_F4 V1.25.0 package at around line 1560, I can se...
Dear,It's not a bug but I think there is a missing macro in "stm32f4xx_ll_adc.h" file of the STM32F4xx drivers version 1.25.0There is a reference to the "__LL_ADC_CALC_VREFANALOG_VOLTAGE" helper macro to calculate the analog voltage reference but thi...
