Hello!I own an STM32F769I-DISCO board which presents an external connector called "JP1" (a picture of this one is given just below) used to power the microcontroller.So, I would like to know:What is the maximum current consumption by this external co...
Hi I'm working with STM32WB5MMG-dk. The purpose is to develop BLE Gateway. The module has a custom GATT svc with 4 GATT char svc which sends and receive bytes, this data is been provided by MSP430 to STM32WB5 vice versa. So MSP430 acts as master whe...
I am trying to use SPI and DMA in a STM32H7, but it is not worling. The spi handler goes to "HAL_SPI_STATE_BUSY_TX_RX" state as soon as i call the function "HAL_SPI_TransmitReceive_DMA" and it does not do anything, it does not even generate the clock...
Hello,I am currently working with 2 Nucleo-G0B1RE board. I adapted the "FDCAN_Com_IT_2_BOARDS" from the G0C1RE-EV example.Clocks are the same, so i think the fdcan is properly setup.I changed the RX/TX pin from PD12/PD13 to PA11/PA12, and connected t...
Is there any way for chips without the Canbus peripheral to read canbus?No external chips allowedMaybe uart or bitbanging gpios?
Hello, I've been trying to port the X-CUBE-USB-AUDIO library onto a STM32G0B1RE nucleo board. Right now, I'm struggling with the configuration of PMA buffers. My configuration right now : HAL_PCDEx_PMAConfig((PCD_HandleTypeDef*)pdev->pData, 0x00,...
hello ı use stm32h750vb , I'm trying to get the adc values in the datasheet.Is the adc operated in continuous mode or in single mode when sampling rates are found.If I run it in continuous mode, I can access the values in the datasheet. But this ...
Hello,I need a clarification whether it is possible to read any pin status in alternate function just as it were a normal GPIO input pin. Is it so?For ex. I configured the alternate function for a pin as a Timer Channel Input Capture pin, yet I can s...
Hello Team,I'm newbie to STM32F030CC, in this 6 USART channels are present, I want to use all the 6 USART's via DMA channels, but the available DMA channels are only 5 and also for Tx and Rx dedicated DMA channels are required, in that case I assume ...
