when I press an external interrupt button, I want to switch to static IP, press again want to switch to DHCP, how can I get this? because in CubeMX it just defines once for LWIP_DHCP macro and how can I use this for static IP or vice versa ?
If I comment out the instantiation, compile and run, then uncomment the instantiation, compile and run, the code will work fine from that point on. But it will not run without hard faulting unless I do the comment / uncomment thing. Here's the code f...
I enabled WWDG on the MX and there were no other settings. MX_WWDG_Init(); As the function executes, the CPU resets, and when I look closely, I see that __HAL_RCC_WWDG_CLK_ENABLE(); As soon as the function runs, the CPU is reset. What should I do?Bel...
Hello,Didn't found a better way to ask this question elsewhere.I was registered to watch STM32 Innovation live on March 7, but I didn’t have enough time to watch it completely.I tried to register again on this page: content.st.com/stm32-innovation-li...
Hi everyone,I'm trying to transmit and receive data through rs485 with uart. Using Uart with DMA in normal mode and referance from this project. https://controllerstech.com/rs485-module-and-stm32/However, in this project there are 2 different stm. I ...
Using Stm32l4r5zi-p nucleo board current consumption is not matching with datasheet it is much higher like 130 -200 mA higher let me know any idea to reduce the current consumption
I am using the STM32G0B1 and would like to use the internal VREF buffer to drive VREF+ for the DAC and ADCs. I found the following presentation detailing its use:https://www.st.com/resource/en/product_training/STM32G0-Analog-Voltage-reference-buffer...
Uart communication did not work in the existing project file.There may be other interference, so I created a new project and wrote only Uart, but it is the same.The input of the signal to the RX pin is confirmed by the oscilloscope, but it does not w...
