My version of STM32CubeIDE is Version: 1.0.2 Build: 3566_20190716-0927 (UTC)The STLinkUpgrade app is 3.2.11. It says that the last firmware version is V2J31M21. However the latest version of ST-LINK/V2-1 firmware (V2J34M25))? One can use the standalo...
Pre-sales question about STM32H750B-DK
I note that the STM32H750B-DK comes with an attached display. If required for evaluation / development, can a larger display be connected in its place? Something in the 8" to 10" range. Touch is not needed. If so, can you recommend any brands and/or...
How to enable SWO with OpenOCD + ST-Link?
How to enable SWO with OpenOCD + ST-Link? Is that possible with st-link v3 and STM32F407?
I want to make my own hat for the STLINK-V3SET but i cant find any files of the exact positions of the STDC14,CN3,CN4 headers
Does someone know if these documents exist or the poistions of these headers
STM32 Nucleo-64 for STM32L073 gets very warm
I got a STM32 Nucleo-64 for STM32L073 board from Farnell. A few seconds after I had connected it to my PC via USB, it got so warm that I could not touch the CPU. They then send me another one, but it has exactly the same problem. I have tried setting...
Should HAL_UART_Transmit work with RS485 or is there a different send function?
I'm running absolutely bog standard STM32CubeMx code on NUCLEO-F091RC to get RS485 working (NOPs added for debugging).If I scope the USART2_TX line (PA2) I see no data.There is data on the USART1_TX line (PA9) and the RS485 enable line (USART_DE PA1)...
Resolved! ST-Link broken after upgrade on Nucleo card
HelloWhen I try to connect to my Nucleo board, I have the following message:Error in initializing ST-LINK device.Reason: (4) No device found on target.I think I have this error message because I didn't disconnect the board physically before upgrading...
Ambiguity in board+pin parasitic capacitance assumption
Hi,I am trying to calculate the oscillator parameters for STM32L433RBT6 microcontroller. I referred the STM32l433xx datasheet as well as the "AN2867 Oscillator design guide for ST microcontrollers" application note. The STM32L433xx datasheet provides...
[Very Urgent Help] The STM32F042K4T6 integrated sometimes does not work. I'm restarting the system from the NRST pin. If I'm throwing resat 10 times, the system works in 8 and the microcontroller does not start in 2 of them.
Hello EveryoneI design oven timer (transformerless) with STM32F042K4T6. Although I tested everything separately there is a problem in the pcb. When the system first comes on, the system works but sometimes it doesn't. I tested it 10 times and the MC...
