Hi,Please find attached, Below is the schematic which i prepared for custom PCB using STM32F103C8T6 MCU. But i am unable to enter in download mode. I have tried placing same jumpers for boot mode as in Blue Pill.Only component i have omited is 32.768...
If I write HAL_Delay in the main function, then code execution gets stuck at this place.int main { HAL_Delay(1); }Code execution does not exit the loop at this point.while((HAL_GetTick() - tickstart) < wait)I think because the SysTick_Handler interru...
this part in my code completely making my prototype to sleep which should not.As my standby should workout if the main power supply is OFF for 30 seconds.I have tried shutdown mode and exti thats too behaved the samePlease help what may be wrong _...
Hi, I try to make a project that seems easy. but I am not good to code so I ask ChatGPT but still I need human GPT to help. appreciated 1) hardware STM32U585 ( (B-U585I-IOT02A)2) use software generate 0 to FFF and output analogue voltage to Pin PA4...
Hello, I am using STM32F446RE in my project and as per the project requirements I need to have power on built in test, initiated built in test and continuous built in test on STM32F446RE. Please let me know how different built-in self-tests can be ...
Hello,I am currently developing a DSP application on an STM32F439ZI Nucleo board in combination with a Pmod I2S2 audio codec board. So far, basic testing and filtering worked fine until I started to try FFT processing. I isolated the issue in a simpl...
Dear all,I am using NUCLEO-H745ZIQ for the UART communication.I try to use the UART RX Interrupt to get the data from PC. I set the UART parameters as same as I was use for the STM32F4 which work fine. Currently, I would like to use both of CM4 and C...
Hi, I would like to make a serial to usb converter. The problem is that I need to make a usb-to-32 serial port converter.I've seen that there is nothing like this on the market and not even chips that do this.What I came up with, is to use STM32s to ...
Hi everyone,I am developing an application using the STM32L476RG MCU with FreeRTOS v2, FATFS and an SD card. I am storing sensor data in a .bin file onto the SD card and I want to enable the USB Mass Storage functionality to get .bin files onto my PC...
I was using HAL Driver for DAC, however, it turned out not to be suitable for my project because at high sampling frequency, using HAL_DAC_Setvalue() inside a timer interrupt caused problem. So i need to write my own driver for DAC. But I have no ide...
