STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi! I want to connect to old hoverboard but I can't make connection to mcu. I don't have idea why. I try a lot things but nothing worked. The chip is stm32f103rct6. 10:20:01 : UR connection mode is defined with the HWrst reset mode10:20:01 : ST-LINK...
HiWhen I was returning from RDP level 1 to 0 the stm32cube programmer program crashed and now every time I try to access the microcontroller several different cases happen:1- Connect and instantly lose the connection giving the next error: Error: Dat...
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...
Posted on March 14, 2014 at 16:03If someone could give me an idea, that'd be great. I need it to speed up math operations.
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...
