I want to make USB which is operating in Device mode to enable pullup and pulldown resistors and reset without built-in VBus sensing pin. I've tried HAL_PCD_DevConnect(&hpcd_USB_OTG_FS) but it didn't work.How can I command USB to start working ?
Hello I have a question about writing hex file in MCU (STM32F767xx) without a development board.I want to draw my PCB schematic but I am confused about which pins are used to flash the memory.I tried finding it on the datasheet but with no luck. Cou...
Hello,I just bought a STLINK-V3 because of its faster USB interface to speed up debugging with STM32CubeIDE. Unfortunately I cannot get it working. With some settings the target is not found with others there are errors during flash programming. Does...
HelloI implemented an external flashloader for STM32F767 for an external SPI Flash. The size of the flash is 256MBit. I want to readout the whole flash with *.bat file. I tried with this line:STM32_Programmer_CLI.exe -c port=SWD reset=HWrst freq=800...
Hello,I am facing a huge problem for three days, and I don't have any beginning of a solution...I made a PCB with an STM32L476 and a LoRa chip SX1272. I am using the code given by ST ICube LoraWan. After a join success, I start a custom timer and I s...
Are the VCAP_1/VCAP_2 external capacitor decoupling capacitors ? (when using the 2.2 uF with power regulator ON) PowerSupplyScheme page 77:
I have followed Video "STM32CubeIDE basics - 03 GPIO HAL lab" as closely as possible for my hardware as closely as possible and get the following results in the console:STMicroelectronics ST-LINK GDB server. Version 5.5.0 Copyright (c) 2019, STMicroe...
We use STM32 microcontrollers pretty often, and I took stm32g030f6 for some specific project. I used STLink-2 + openocd before, but I think I cannot use it on that particular one. So I take JLink but I don't have much experience JLink. I spent whole ...
Hello,today I've received STM32L0538 Discovery kit. The problems started right away. After connecting it to my PC via USB 3.1 port, the board gets the power, but does not work. LD1 lights up to green and LD2 to red, but LD3 and LD4 stays off, the pap...
Hi everyone,I designed a custom board and now I found two MCUs (STM32L4A6VG) are breakdown. The MCU is running at 3.3V and all VDD, VDDA, VREF+, VDDUSB and VBAT is connected to the same 3.3V source. Here's what I found.For the initial trial, I did 2...
