I've download the CMSIS pack for STM32H7 series. ST implement an I2C driver function like this:int32_t I2C_MasterTransmit (uint32_t addr, const uint8_t *data, uint32_t num, bool xfer_pending, I2C_RESOURCES *i2c), but the website, https://arm-soft...
Which is better for network communication, STM32F429 or STM32F407? I would like to ask for your opinion and whether it is possible to use DMA transfer? Or if there is a better solution？ thanks!
Hello, F407VET TQFP100 on custom board, ethernet PHY LAN8742A, STMCUBEIDE 1.6.1 on Linux (mint). PHY and MCU both clocked by 25MHz oscillator, reference clock 50MHz is OK. Cpu running @168MHz FREERTOS 3 task: default init LWIP, start HTTPD thread t...
Using USBPD 1.3.0, DRP_VDM project running on P-NUCLEO-USB002. Adding SOURCING_DEVICE macro.STM32 is UFP (after Data Role Swap). The DFP requests Discover Identity of the SOP' but the STM32 answers with GoodCRC and never ACKs the Discover Identity.It...
We have a project written with LL library. We want to add SelfTest functions to this project. However, the SelfTest libraries we downloaded from the site were written with the HAL library. Since we have a memory problem, we need a version written wit...
Hello,It's available a tutorial for configuring ethernet LAN in STM32F769 DISCO using LWIP stack, CubeMX and STM32CubeIDE?
Hello,I'm using an stm32l151re to interface with mp34dt05-a mems microphone. I'm using it to determine noise level. The communication between smt32 mcu and the sensor is based on I2S protocol with dma. My issue is that my project consists of multiple...
I created a two task one is for my gsm modem communication through uart and another task is for Bluetooth communication through uart, gam modem communication task is stuck while bluetooth communication task receive data cintinuously.How to resolve t...
Hi,I am migrating some USB code which was initially developed on STM32F0. There are 6 end points in use (including control):EP address:0x0 0x800x87 - 0x810x010x82So my code to config PMA in USB_LL_Init:HAL_PCDEx_PMAConfig((PCD_HandleTypeDef*)pdev->p...
Hi, I am evaluating MEMS microphone for our application. I am using on board microphone MP34DT01-M in STM32F779NI-EVAL. I am using DFSDM example in STM32F7cube package and able to hear the speech. Now I want to filter the frequencies higher than 1KHz...
