I am planning to develop fingerprint device based on STM32H7R3V8 or similar. It will have 1:1, and 1:N finger matching, and communicate over LAN, WiFi.Will the above MCU be sufficient for a 25,000 users (i.e. 50,000 fingerprints) capacity device and ...
I am trying to enter USART1 bootloader (Pin PC4 and PC5) for STM32G474RCT6 MCUWe are following AN2606 and tried to keep the option bit configurations as per the highlighted row under pattern 14Bit status:The Boot0 pin (PB8) is NOT pulled down with r...
Hello! I am currently working on a project involving a NUCLEO-F746ZG board that is connected to a local NTP server and another board (let's call it X). My board needs to be synchronized with the NTP server and receive 3 pairs of timestamps from board...
I am trying to implement usart2 tx with dma1 stream 6 channel 4. I have tested the usart2 tx independently and it worked perfectly, but the dma part was not that lucky, it just wasn't send anything and I couldn't find anything wrong in my code. Appre...
As a newbie C developer and Stm32 user. I'm trying to develop a 433MHZ RF remote receiver with my custom made board using stm32f030c8t6. I tried to decode the RF signal on an arduino by using rc-switch library, and I can decode the 32bit signals as b...

Hi everyone,we have prototype with three STM32F030RC and with very strange behavior. All mcu has shared NRST (pulled up, for testing not externally driven) and BOOT0 (for testing pulled low permanently) pins. For a testing purpose I created clean pro...
I am transmitting a CAN signal using bluepill but there is no signal on the CAN Bus. I added two counters which will check whether transmission was successful with the following code.if(HAL_CAN_AddTxMessage(&hcan, &TxHeader, TxData, &TxMailbox) == HA...
I'm using the HRTIMER_F on an STM32G474 running both TF1 and TF2 (half mode with deadtime insertion)I'm trying to setup a window where a capture from an external event can occur (COMP3_OUT). The interrupt from the capture is triggered regardless of t...
Hello, I am using the STM32U575RG microcontroller, and I am developing a board with a NEO-M8N model GPS, and I am using LPUART1. However, I am wanting to implement it with DMA. Could someone help me explain how to configure the microcontroller with D...
