Hi,I'm working on STM32F779NI MCU. For our PCB, we have used 32768 Hz LSE crystal for RTC, which has a tolerance of +/-20 ppm. However on long-run testing, a time gain of around 6 sec in 25 hrs was observed, which is higher than the stated tolerance....
I'm investigating if it is feasible to implement ethercat slave on an stm32f7/stm32h7.I found the I-NUCLEO-NETX. But can't buy it farnell/mouser/digikey. and hilscher is very secretive about any information. So are there successful implementation of...
I am new to Nucleo board STM32F411re.I am trying to work out an UART example on the devlopment boardI am trying to send data through UART - TX line and trying to read that data using Putty. I can't able to see data in Putty. When I debugged I saw dat...
Hi, I have tried transmitting data bytes in Tx ,which is correct along with CRC, As, no acknowledgement is found from receiver side, it retransmits continously and ofetn leading to error frames.
I expect at least 22937 samples until the array is full. My guess now is, that my index counter "number_of_samples" rises faster than that the actual samples that are written into the array. After the index counter reaches the theoretical max value o...
Hello, I trying to test Demostration Firmware(*1) for my STM32L552E-EV evaluation Board, and in the documentation for this Demo is written:<<This demonstration has been tested with STM32L552E-EV (MB1372-C02) evaluation board and can be easily tailo...
Required MCU with camera, Display and Bluetooth Interface with at lease 512 KB RAM. or nearby requirements
hi, i want to store some bytes ( 4 Bytes) of data in MCU flash registers in program run time . In flash user locations are available or not. If available how can i assign the bytes to flash locations in run time.
The new STM32G474RE has an ADC that can run up to 4MSPS.I'm doing a project where I need to do the sampling in 1MSPS. But the maximum sample rate achieved was 300kSPS. When I set timer 1 for the ADC trigger to 500kSPS the "while" loop simply locks. S...
