STM32 MCUs Embedded software

CubeHAL I2C slave pulls down clock line and let it not go. Who knows what I can do when wanting to enable clock stretching.

Hi, I have problem with I2C. I use NUCLO446RE as a slave. STM32Cube FW_F4 V1.24.0 or 24.1. Both versions have the problem. I using also Atollic True Studio for STM32 or STM32CubeIDE 1.0.0. The problem occures with both platforms.When the master reque...

Anybody having success using HNP on USB OTG for STM32 MCU's?

Poor H7 Ethernet Rx Descriptor DMA handler implementation.

Took me quite a while to work through this lot, identifying what was actually going on, but here's a heads up for anyone else. The symptoms I was seeing were TCP failures in high traffic conditions (~ 0.2ms per rx). In particular, accessing port 80 /...

changing timer output polarity fail in toggle mode

I use the STM32G0 Timer2 to generate phase controlled signals. For negative phases the output needs to be toggled; After reset the state is always correct, but during runtime the OC polarity is not set correctly.Here is my function. Can someone told ...

USB Another OUT Endpoint

HAL bug: HAL_TIM_PWM_Stop() function stops timer even when another channel is configured for input capture?

Hi,I'm on a L011 device with the following configuration for timer 2:Channel 1 is in input capture mode, rising edge. The timer itself is in auto-reset mode, on each rising edge on channel 1 the timer count is copied to the CCrx register and the time...

hi i want to make advancement in transducer is want to add modbus and usb in that.the current design is on 8 bit STmicrocontroller. what should I do?

HAL_I2C_Master_Transmit & HAL_I2C_Master Receive never return with HAL_OK using I2C2 Using cube 5.0 generated init's and using the F4_V1.24.0 library.

I2C2 is PB11,PB10 are connected to an AT24CM01 I2C eeprom. I get a few writes to the DR then the hal decided that the device is busy and all other calls fail because the device is busy. My writes and reads are trying to to do 240 bytes, not a very ...

Is there any limitation of stm32f4 in using USB as a mass storage device?

Hello,I need to use USB as a mass storage dvice with stm32f4 discovery.I have a running code from Ub_Lib. But it is not working for all the USBs I have.can anyone help me with it. I am able to make a file but it is not able to write and read from fil...
