Resolved! Could TCPP01-M12 be used without the N-MOSFET?
We have a wide-input power management ic with buck-boost converter. 28V VBUS is not a problem. So is it possible to eliminate the N-MOSFET (at least in Sink mode)? If it is OK, what is your recommendation for connections of IN_GD, Gate, and Source pi...
TCP port number reused
I am using STM32 TCP Echo server client Cube IDE example. I have server and client device. I can connect first time successfully but when I reset the client, I get after 70 line in wireshark screenshot. How Can I solve this problem ? What is the reas...
UM1786 missing HAL_OPAMP section entirely. Revision 5 claims to have added it on 19- Jul-2016.
The documentation for the OPAMP peripheral on the STM32F3 series is completely missing from UM1786. The list goes from (Section 30) "IWDG" to (Section 31) "PCD". Hopefully there aren't more things missing from that range.
Over-current indication on USB host on STM32F2xx
Hello, I am using the STM32F2xx ev board to develop a simple application that utilizes the USB port as a HOST. I would like to check if a device has been connected to the port and it causes over-current on the USB.Looking into the source code, It see...
STM32F4 LWIP freezes after fixed send number
I'm using nucleo f429zi with LWIP v 2.1.2. Documentation states that for TX buffer PBUF_RAM should be used. In my case whole LWIP stack freeze after 28 send messages. When I change pbuf type to PBUF_POOL, everything works like a charm. Although in th...

TCP client error, TCP Port number reused -> STM32f417 + CubeMX + LWIP + RTOS + Netconn TCP client
Hi All, I have written simple TCP client using Netconn interface in LWIP on stm32f417 board. Client connects to LWIP server that is also on another stm32f417 board using Netconn api. After first succesfull TCP transmition, connection freezes, when co...
Resolved! FOTA in STM32L0
For an application, I need to implement FOTA through UART/USB for STM32L0 microcontroller. Are there any examples or firmware packages available for this?
Resolved! Error with timeouts constants in stm32f7xx_hal_sd.c in SD_SendSDStatus and SD_FindSCR cause indefinite hangs.
Both these functions contain the code:"if((HAL_GetTick() - tickstart) >= SDMMC_DATATIMEOUT)"However SDMMC_DATATIMEOUT is defined as 0xFFFFFFFF so the timeout is very long (49 days with a 1ms tick) and therefore never occurs.That upshot is that if the...
