May I ask what is the practical purpose for those half complete transmit/receive either for SPI/UART/I2C callbacks?
I would like to understand more the purposes of these half completed callbacks. Are they for monitoring or catch up filling up buffers purpose.
Trace, Power Profile in on-fusb3-stm32 Evaluation Board and X-CUBE_USB_PD
Hi, Everyone, I am a new user for this board, and I have some questions about how to add the trace in the code and how to modify the power profile in the codeI)In the schematic, we can find out that there are some pinout for testing, I know it is for...
Nucleo-F722ZE USB MSC and SDMMC interface to uSD card (SOLVED)
I tried to create a combination of USB MSC Device and uSD card with SDMMCx interface. The clock for USB was config at 48MHz and also for SDMMC.In the examples that I saw online, one indicate the SDMMC clock need to be configured at 12MHz so it will ...
STM32 + USB PD + Voltage and Current control
I work with STM32G4 and USB PD. I have a question about voltage and current control. How is voltage and current controlled during operation so that the values do not go beyond the limits specified in the profile definition? I found only one place in ...

F767ZI+FreeRTOS+lwip can't support more than 2 clients?
I require to run 3 clients. I start 3 lwip threads using sys_thread_new. Each thread will service 3 python clients via 3 distinct Ports. Everything seems to be working when running only 2 threads . However, when a third client is added things become ...
Resolved! how to prevent the Lwip stack from shutting down after few transmissions in STM32?
I am currently writing a code to send joystick data from a PC to an STM32 Nucleo board. I use pygame to read joystick values and use the socket library of python to send data to MCU via a router. Both MCU and PC is connected to the router. On the MCU...
Resolved! From the audio codec being used in the STM32H745I-DISCO boards it seems that it can support 2W speakers. Where can I find more information on recommended specs for those speakers?
For some context, we are prototyping a mobile device and want to achieve good quality stereo audio so we'll be buying some samples of various low power mobile speakers, but want to be in the right ball park before we iterate on final designs.
