Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
I tried to make a formatted print function, which would not be interrupted by another call to HAL_UART_Transmit_DMA(). I have two threads which freely calls HAL_UART_Transmit_DMA(). If it's not synchronized, the message would be mixed or lost.So I ad...
Hello,I am sampling audio data with sampling rate 16 kHz and then send it using RF to the other MCU which is sending to DAC samples with the same 16 kHz sampling rate, Im using DMA for sending data through I2S to external DAC. The problem is that the...
Hi, I have gone through below link. https://community.st.com/s/question/0D50X0000AIcIc6SQF/audio-player-demo-stm32l4r9idisco?t=1604201466282Is there any demo for audio player from that audio files pop up from USB Mass Storage/SDCard in TouchGFX...
There is hal_pwr.c module, and hal_pwr_ex.c ("Extended") modulesThese seem to have equivalent functions, such asHAL_PWR_EnterSTOPModeHAL_PWREx_EnterSTOPModeHAL_PWR_EnterSTANDBYModeHAL_PWREx_EnterSTANDBYModeWhat are the difference between these? Why s...
I use STM32F769I-DISC1.My program is based on LwIP_HTTP_Server_Socket_RTOS and QSPI_ExecuteInPlace (and https://github.com/vlcekji2/External-Loaders).Basically, in external FLASH I have a program which handles a TCP server. When using data and instru...
GPIO_InitStruct.Pin = I2C1_SCL_Pin|I2C1_SDA_Pin; GPIO_InitStruct.Mode = LL_GPIO_MODE_ALTERNATE; GPIO_InitStruct.Speed = LL_GPIO_SPEED_FREQ_HIGH; GPIO_InitStruct.OutputType = LL_GPIO_OUTPUT_OPENDRAIN; LL_GPIO_Init(GPIOB, &GPIO_InitStruct);Code above ...
I have a third party device that is UART programmable.I need to create a USB to UART bridge with password function (access to the device only after entering the correct password)generated the code using the latest version of STM32CubeMX for Atollic T...
We have an application that's currently using a USB BC1.2 IC to enumerate a charge condition (CDP) between a USB-u sinking host and a sourcing device. We're looking to add an IC between the existing circuit acting as the sourcing device and a USB-C d...
Hi,We are designing the Android accessory and we would like to use STUSB4761 in our application.STUSB4761 can source power and become device by receiving DR_swap from the sinking device.Also we would like to put our accessory to continues in device a...
Hi everyone,I developed a custom board out of STM32F070CBT6 MCU. The board is supposed to handle a simple logic of a 5x4 matrix (similar to a 5x4 keypad). The algorithm I've developed also involves the same logic used in a keypad that is, The rows ar...
