I am using a STM32H743 processor and have ST's LwIP stack running correctly. At least to the point were I can use Hercules as a client and connect to the Nucleo and send a small block of data (24 bytes) to the Nucleo. I have set breakpoints in the co...
Hi everyone,I just picked up a STM32F746G discovery board to practice on, but I can't for the life of me get the built-in STLink to show in windows. By this I mean, I'm unable to power via mini-B and LD7 just flashes red. Once I change the jumper on ...
hello ST,I'm trying to use EXTI1 interrupt for a project. But the Interrupt handler is not firing. I am using the STM32Cube IDE and CubeMX for code generation. I looked into the interrupt enable registers, Mask registers, etc and all seems fine. I am...
I am using STM32 Nucleo-H743ZI2 as a I2C transmitter and Nucleo-G0B1RE as I2C Slave Receiver in interrupt mode, now i am trying to receive Variable size of data i.e. i want to keep Slave receiver size to be Maximum and want to Stop receiving when Tra...
Hi,i am working on STM32F302R8Tx and i would like to have a 490 Hz PWM on Timer15 Channel2, attached are my configuration and my code, when i measure it , i become 491,13..Hz. what can I do to get the exact 490Hz? Any Suggestions?? thank you!!! ...
Hi All,I'm using RCC both the crystals on PC14- 15 and PH0-1 and I want to use JTEG TRACE with 4 bit synchronization but when ever JTEG TRACE enable RCC showing warning "status: Parity disbale conflict with debug jteg 4 pin"Kindly let me know what t...
Greetings !I am very new to Controllers , I need to enable and ping the Ethernet on STM32F756G-Eval Board .Can anyone kindly suggest me with the steps/procedure to enable Ethernet in STM CubeIDE so that I can ping from my PC.Thanks
Greetings for the day,I'm working on STM32H745I Discovery board for 4.3 inch Touch Screen Controller ( GT911 i2c interface) able to control LED by touching flex button, working fine as per our requirements (for reference).We're using our customized b...
I am experimenting with the USB HS peripheral on the STM32U5A9NJ Discovery Kit, and noticed that there is a signal called VBUS_SENSE which is routed to PG1 (ADC4 IN8). I've configured ADC4 to sample from this pin, and notice that the sensed voltage i...
Hi,i made up this circuit, to protect the input of the MCU. The switches pull to GND with 0 Ohm to 22kOhm, and this is also where the ESD would come in. The output_line also goes to a MCU input, and its the one i am not sure, if its protection is eno...
