For the life of me I cannot get the I2C pins on my microcontroller to output anything.I am using I2C1 on pins PB6 (SCL) and PB9 (SDA) on the STM32F746VGT microcontroller. The pins are hooked up to a TXS0108E level shifter that has built-in pull up re...

STM32CubeProgrammer v2.13 was giving me the famous "Failed to execute MI command" and "Failed to download Segment[0]" errors within the STM32CubeIDE, so I downloaded the standalone STM32CubeProgrammer v2.10 and it works fine. The IDE still uses v2.13...

Thank you so much for your help, everyone. I ended up solving the issue in the most anticlimactic way possible: the oscilloscope was bad. After switching to one that I've used before and know how to use better, I could see the I2C lines just fine. Th...

The code fails here inside HAL_I2C_Master_Transmit:while (hi2c->XferCount > 0U) { /* Wait until TXIS flag is set */ if (I2C_WaitOnTXISFlagUntilTimeout(hi2c, Timeout, tickstart) != HAL_OK) { return HAL_ERROR; } ... } It nev...

I disconnected the level shifter chip and probed the SDA/SCL lines directly with pull-ups enabled and tried to send I2C data. Still nothing, both lines stuck high. They go low when I hold down the reset button, then get stuck high as soon as I releas...

Thank you! I was pulling my hair out trying to override __io_putchar() and _write() and fputc() and not seeing any of those functions getting called by printf(). Adding fflush(stdout) made it work.

You do not need to manually call MX_USB_HOST_Process() when using RTOS. As long as you enable USBH_USE_OS under Middleware->USB_HOST in the .ioc file, the automatic code generation should take care of it for you.In my case, it inserted a MX_USB_HOST_...
