I already wrote a about this to pinned release thread, but as there is no public tracker I don't know if that was the correct place, so I decided to a make a new thread.On macOS, it is not possible to type '@', because ALT+L is hard coded for 'Login'...

I'm using the UART (USART5) with RS485 and I have enabled the read to be on also when sending. I need to read back the data that was sent to see if it is correct. The problem is, that I do not receive what was sent. But if I send the same data from o...

I have the problem on my STM32H753, that the IDLE-bit is set when transmitting. On the manual it says: The IDLE bit is not set again until the RXFNE bit has been set (i.e. a new idle line occurs).The RXFNE is never set (actually on CubeIDE this is sh...

Using the KMS/DRM driver, how can I change the emulated framebuffer format? I'm using simple-panel and the framebuffer has always only 16-bit color even though the driver explicit sets the format for 24-bit colors (.bus_format = MEDIA_BUS_FMT_RGB888_...

Next problem with my board is the RS485. I can send bytes, but can't receive because after sending once the DE stays always high. Without sending receive of course works.&uart5 { status = "okay"; pinctrl-names = "default", "sleep","idle"; pi...

@Semer CHERNI On macos can't type '@' (alt + L) because it is hard coded to 'Login'. At least I can't find it on the list Preferences->General->Keys. Well, it is shown in csv if I export the list, but I can't find it on the list where I can change th...

The reason for this behaviour is that I did disable and enable receiver, which leads to a new IDLE condition.

Thanks @TDK for pushing me to write an example. As the example worked, I found in my original code that, when enabling the RS485 driver to send, I also disabled receiver because I did already have another UART (also RS485) doing something else and th...

The half duplex in STM32H7 would be only TX pin acting as transmitter/receiver. And if you would have checked the registers I posted, you would see that, that is not the case.

Well, I did show my transmission code. As I'm only testing, the code is sending 1 byte once in a millisecond with LL_USART_TransmitData8(UART5, 0xAA);It does nothing else. And this command only writes to UART5->TDR. No disabling RX or changing any ot...
