I've got an audio codec chip with bidirectional i2s interface, but I can't find any examples or any other info on configuring bidirectional i2s through SAI and HAL in stm32 microcontrollers. I am able to configure single-direction i2s just fine. How ...
Hello, I am an engineering student who has just begun working on a CubeSat project for my design class. We are working on the OBC, specifically looking at developing a bootloader at this time. The OBC components have been selected by previous teams a...
Hello,after programming the code via the OnBoard ST-Link and connecting/disconencting USB on the Device side in order to find out if the works, I can no longer access the microcontroller.I have no idea what the rootcause is, 3.3V is fine. Could it be...
So the Blue Pill guy checks almost all the boxes for a new project I'm working on soon. 3 UARTS, M3, 72MHz, USB device, cheap, powerful *but* I'm not clear on the "fix" for being able to re-enumerate my device on USB. I must be able to change device ...
I want to use the bootloader feature (via UART) of the STM32L071RB. I have read the AN2606 and AN3155.If I'm right, the STM32L071RB has a V11.x bootloader and can be updated via UARTx, SPIx,and I2Cx.Is is possible to configure, which pins are used by...
Hi,My software sends a CDC bootload flag that asks the MCU to do a bootloader jump. The jumps works fine and I have no problem detecting the device change, in "control printers" on my PC (CDC to DFU). But on my collegue's PC his Windows does not see ...
I followed the custom hid example and finally got it to work, I can send 64 byte packets back and forth. The only issue now is that the device shows up as a mouse in the windows devices dialog.How can I change it to show up as a generic deviec?
