When I send data from esp32 to stm32, it works fine. But when esp32 initially receives data from stm32 using uart, the data seems to have some random characters.When i send 75, it looks like this in serial monitor:Received: %$^#^12Received: 12Receiv...
I have developed a custom controller that uses the STM32G474RE to regulate the output voltage of two power supplies.I am now developing the code to implement a peak-current mode controller for each of the two power supplies. Is there a way that I ca...
I have connected 100k NTC with 100K PU resistance. ADC is measuring voltage on NTC is 1580 mV. While multimeter shows 1410 mV. 1410mV is correct number as it gives 32 degC temperature.I am using ADC in polling mode. I added HAL_ADCEx_Calibration_St...
HI,I'm working with a micro from the H7 family (H723).I have to implement CAN communication on two distinct peripherals (FDCAN1 and FDCAN2) in interrupt mode but the system doesn't work.Below are the settings I use in my project: void MX_FDCAN2_Init(...
Hii everyone!We are working on CAN , and MCU is stm32f103When we are taking output on blue-pill Tx and Rx pin Data is comingBut when are are doing same on custom board data is not showing ,we are uploading same firmware and clock configuration is als...
Dear,we use EEPROM in our project with STM32L152. It seems like in some MCUs is erased random part of the Eeprom. It happens very rarely, and probably most likely when VCC is disconnected from PCB (MCU). Any solution, any similar experience?Best rega...
In our system with SMT32G041F6P6 powered by a battery, device gets to hung state when kept idle for few hours or days (randomly). We have already implemented a window watchdog to detect any faults. Even with watchdog enabled, we are getting this han...
I need to make 2 DAC channels 4bit each. I plan to use QSPI in double flash mode.Task is to play prerecorded samples from RAM cyclically. Samplerate is 45Msamples/secondI plan to use DMA in circular mode to send data from RAM to QSPIAre there limitat...
I have been trying to use the FatFS file system to create a new file on the SD card, or to read a simple txt file on the SD card. However, I seem to be running into issues after mounting the SD card. Initially, I ran code to:- mount sd card in main- ...
