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...
I have a homemade STM32F405RG development board It has a momentary switch that puts Boot0 HIGH to put it into DFU mode when plugged into USB but if I just plug it in it does not show up as a Virtual Com Port. How can I have it so I can have both the...
This function uint32_t LL_RTC_DATE_Get(RTC_TypeDef *RTCx) reads 4 times the DR(Date register) to take the date from RTC.After the first read, the shadow registers are unlocked (in case don't bypass them). The next three readings from DR register m...
I want to interface pen drive with STM32f407. Any example code for this?Using STM32F4xx_DSP_StdPeriph_Lib_V1.8.0 in my code.
Hello,I am trying to enable USB DFU functionality on a custom board with STM32L496 MCU.Only D+ and D- pins are routed from the USB connector to the MCU, ID is not routed at all and VBUS is only to power the board. I added a code in my firmware that j...
Hi everyone.I'm desiging a low power application and clearly the most intuitive wayto reduce power consumption is just to turn off what we don't need.And here a doubt about the GPIO clock management raised.AFAICT, __HAL_RCC_GPIO_CLK_ENABLE should be ...
Trying to connect two FS devices to an STM32F722RET. Datasheets are a little vague, but seems it should be OK as long as I don't do HS.Using cubeMX, and for the FS port (PA11/PA12) - things work great. For the HS port (configured to be host_only, F...
Hi everybody.I'm met several scenarios in which the use of HAL_PPP_MspInitwould be too constraining.A typical example is when I'm making a reusable library that needssome peripheral. If I initialize the low level resources for the peripheralsused by ...
Hello,I have a working board with a STM32F429ZIT6, 144 pin MCU, which is fine.I also can update in the field, this MCU using the internal bootloader ( AN2606). However, I ve noticed something odd.During the bootloader (using stm32flash utility UART1 ...
I am new to STM32 and CubeMX. I need to write a program to send and receive data from a module via UART port. I have to send(Transmit) a data to that module(for eg. M66). Then I would return to do some other tasks. once the M66 send a response to tha...
I am using STM32L051K8 MCU in my project. All the project has been developed. Now there is a need to provide OTA firmware upload. For that I require to use I2C bootloader as I have alreadey interfaced I2C EEPROM. Please let me know whether it is poss...
