Posted on November 27, 2017 at 15:24I am using the SAI in my custom F7 board in slave RX mode. I am having trouble receiving SD from the audio codec. In debugging this issue I noticed that the HAL code generated by CubeMX does not have a configurati...
Posted on December 05, 2017 at 15:34I have a custom F7 board configured as a USB HID device (using CubeMX generated code) that won't enumerate with my PC host. However, if I pull BOOT0 high, it will enumerate as a 'STM Device in DFU Mode'. So I assu...
Posted on December 04, 2017 at 10:55I am working with the stm32f7 microcontroller and I have 2 projects, a bootloader project and an application project. The bootloader resides in the beginning of the flash memory and the application resides in the ...

Posted on November 20, 2017 at 22:35On a Nucleo board, is it as simple as pulling the 0 ohm resistor off SB45, and connecting a coin cell [something like a CR1220] to pin33 [VBAT] and ground, in order to have battery backup for the RTC registers?
Posted on December 05, 2017 at 01:15I was wondering if there was any explanation for having several Port E pins (10-13) set to Input (00), and pin E11 is staying high even though there is nothing connected to it. I have tried setting the GPIOE->PUP...
