Resolved! Why won't DAC channel 2 output higher than 0.5V on STM32L432 ?
Hello,I'm trying to use both channels of the DAC on STM32L432, but I'm having a very annoying issue: channel 2 only goes up to 0.5V! I think I've configured both channels correctly, because both channels output voltage that changes with my code... b...
How can I upgrade the firmware on STM32 F446RE by using UART pins from Linux?
I tried upgrading the firmware on the STM32 F446RE board by accessing the usb-dfu. I used DFU-UTIL library for it. But as it turns out, we won't be able to upgrade the firmware using usb-dfu if the code already present on the board has UART or SPI or...

Incomprehensible behavior with the LWIP library.
Recently I switched to STM32F767ZI using LAN8742A and the LWIP library. Began to develop a web configurator based on this STM. And there is such a problem. where 192.168.97.200 is a device, 192.168.97.1 is a client (computer).During data transfer to ...
Resolved! My STM32F3 I2C won't send a start sequence.
I am using the STM32F30x_DSP_StdPeriph_Lib_V1.2.3 library following instructions given in stm32f30x_12c.c for the initilization:#define I2C_SHORT_TIMEOUT ((uint32_t)0x1000) #define I2C_LONG_TIMEOUT ((uint32_t) (10 * I2C_SHORT_TIMEOUT)) #define I2Cx_R...
STM32H7 ethernetif RX buffer zero copy buffer overflow.
There have been multiple complains in the past about the efficiency of the zero copy RX and TX Ethernet buffer management. But this is not solved in any of the past releases. It is getting very difficult to build a real project out of this. I suspect...

Vbus +5V
HiI plan to include the USB input of STM32F303 and am not willing to power up the board with the +5V of Vbus. The board will be supplied permanently with 3.3V. Is it necessary the connection of Vbus? If yes how i should connect it to the +3.3V Vdd of...
