A lot of busy waiting in STM32F4 HAL USB libraries? Not RTOS friendly?
I want to implement an USB host MSC class for concurrent log transfer to an USB stick inside an RTOS context. I have seen the newest USB host device librarie implements an RTOS / CMSIS interface. But I have seen in code that there are still a lot of ...
How to activate debug messages for LWIP?
I was able to activate the messages for USB Host, but I am not able for LWIP, it seems that there is a specific combination of options, so that messages are enabledThank you./** Enable debug message printing, but only if debug message type is enabled...
stm32 cube dma memory increment dont work
Hey guys.I generated a cube uart transmit receive dma but in case of receive only the first byte of my buffer is overwritten and memory wont increment.Whats the problem?
In Discovery-f746g, can connect USB mass storage to qspi external flash accessible for PC OS?
I want to use STM32CubeIDE, then what are must be checked in STM32CubeMX configurations, including middlewares if needed.
HAL_SMBUS drivers for STM32L0
Hello,I am trying to use HAL_SMBUS drivers on STM32L0. The STM32L0 is the slave and I want to read / write registers via i2cget and i2cset on the linux host. I do not need the full SMBus/PMBus middleware, just looking for a simple example with SMBUS ...
Do I can reproduce sound with L031E?
Hi, I need choose a STM32L0 microcontroller for reproduce sound, I had thought choose L031E because is smaller and it have few GPIO, but I don't know if I can reproduce sound whit it. I don't need many GPIO, that's way I though about it.Caracteristic...
overriding osDelay function
Hello,stm32F4FreeRTOSCube 1.4.2My code sometimes run pretty long osDelay. In fact "long" means "longer than watchdog"..I thought about cutting the delay in smaller delays and call a watchdog kick after each delay. Something like this:osStatus delay(u...
Full-Duplex I2S with *Master Clock Output* on STM32H7 in STM32CubeIDE?
we have just purchased a NUCLEO-H743ZI board. upon configuring a test application to work with an audio codec, we found that there is no option to enable *Master Clock Output* when I2S mode *Full-Duplex* is selected.we were wondering what the rationa...
My board has two I2S interfaces, but the DMA controllers are only connected to one of them. Should I use the DMA for audio in, or for audio out?
I thought I had checked everything about the F767ZI Nucleo-144 and its pin availabilities. Unfortunately I overlooked that I2S_A is the only one whose peripheral pins are connected to the SPI_RX and SPI_TX regs for DMA streams.This means that for my ...
