Quectel GSM/GPRS AT Command

Anyone Have Example Code of Quectel GSM/GPRS AT Command using UART With STM32 ?If anyone have example code for the same please share with me Thank you in advance

Resolved! Wrong tick period at 180MHz STM32F446RE

hi everyonei have a strange problem when i try to set clock frequency at high speed.i'm using CubeMX to configure the system and developing on AtollicTrueStudio.i’ve noticed some weird facts setting the clock frequency more than 120MHz.first, is that...

How to reset SPI using HAL functions using Nucleo - L073RZ

I am working on a SPI project (using DMA) as a slave and things seems to work fine but after an hour and maybe more in some cases I see one error and that locks the dma ....I can detect when that happens but I have problems to reset the SPI interface...

Resolved! How to use the 'HAL_UART_Receive_IT' for receiving large data like from GSM ?

Hello guys, hello @KnarfB ,@Community member I am struggling with this thing from past one month. I am using Quectel M66 gsm module and stm32f030cct6 controller. I am not able use UART interrupt for receiving large data when using gsm over uart. ho...

Resolved! STM32L1 TIM10/11 trigger selection, reference manual is inconsistent

Hi, I'm trying to measure the frequency of multiple signals using the STM32L1515RC. Using the External clock mode 1, I need one timer per signal. My question is if TIM10 and TIM11 support this mode.The TIM10 and TIM11 block diagrams (Figure 131, Figu...

I plan emulate on I2C 24LC64T, simply use STM32 as this IC on I2C. Exist an working project ?

I ask not for internal EEPROM emulation, but i store some bin file in STM flash and provide for other IC this data whe request.

CAN baudrate error for the STM32F756-EVAL2 example projekt.

Tried out the example in STM32Cube_FW_F7_V1.16.0 and couldn't get the baudrate to match the description.Have any body else encounterred this problem?

QUAD SPI Communication between two STM32H7 boards

Trying to transmit and receive data between two STM32H7 boards using QSPI.As we are new for using QSPI communication,we generated code using STM32CUBEMX and not able to transmit and receive the data.The screenshots for communication between two contr...

Resolved! STM32F469I-DISCO virtual com port USART3?

Hi there,My new STM32F469I-DISCO just arrived I stumbled upon this part in user manual (UM1932):4.11 Virtual COM portThe serial interface USART3 is directly available as a virtual COM port of the PC connectedto the ST-LINK/V2-1 USB connector CN1. The...

STM32 UART DMA reception fails to update memory buffer from peripheral

Hello ST,I'm using STM32H743ZI. Here I'm connected to 2 external devices(1 for PC UART5 and other for another MCU UART7), both are connected via UART.I'm using DMA with UART7 for receiving data from MCU. UART5 which we use to communicate with PC(Mast...
