I use a STM32F105. On the board there is a bootloader and I upload the firmware through USB (host, OTG_FS). Then I use the USB to extract a log file (.txt). The extraction of the log works only if the optimization of the code is 0. If I set optimizat...
Hello FolksI dont have access to boot pins to enter system memory to use st bootloader for flashing the stm32 micro. There is an option to jump from user code to bootloader code but I want to keep read protect level 1 in option bytes. So if I erase t...
We are using STM32L496RGT controller in our product, the controller flashing (Program uploading) doing through USB. Initially device flash properly, but after multiple time flashing device shows error i.e USB USB not recognized, or port is not detec...
Hello, I'm developing an application for the STM32F302R8 using the STM32IDE.What is happening that any pin I choose as external interrupt EXTI, when the pulse that is free from bouncing (I checked with the oscilloscope) the EXTI handler is called sev...
Hello,I'm using VCP to communicate with an STM32F303 device, which works well.However, when I plug a second device on the same computer, it fails to enumerate properly with the message 'This device cannot start. (Code 10)'.Is that a known issue?Is th...
Hello, I have a very basic question, I want to enable TIM6 to use it as a tool for generating delays, but I am getting trouble just making TIM6 to work.Cube MX generated the following code:static void MX_TIM6_Init(void){ /* USER CODE BEGIN TIM6_Init ...
I try to configure TIM15 PMW channel1 - PF9 and channel2 - PF10 using LL driver.Looks like the STM32CubeMX is generating the wrong code.It set GPIO mode as AF_2 GPIO_InitStruct.Pin = LL_GPIO_PIN_9|LL_GPIO_PIN_10; GPIO_InitStruct.Mode = LL_GPIO_MOD...
"HAL_RTCEx_SetSecond_IT" doesn't work on Stm32vldiscovery.Instead of that "RTC->CRH=RTC_CRH_SECIE" works well!The code (see 102 and 103 lines) is in the attachment.
Try to play the wave file stored in uSD using STM32F103VCT and CODEC IC (TAS2505). Use 4bit SDIO (DMA) and I2S2 (DMA) with STM32 and CODEC. However, after playing Wave file, a hardware fault occurs and HardFault_Handler is called. If Wave file is pla...
I am trying to achieve the lowest power consumption possible when entering Stop2 mode with the STM32L476. I have verified that all of my GPIO are in the correct state before entering Stop2 mode. I am also very confident that it is not any external ci...
