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...
I'm trying to build a double buffer (or ping pong buffer) using the HT (Half transfer) and TC (Transfer complete) interrupts. Also, I'm using DMA with circular array and ADC is triggered by a timer at 6 kHz. I have the algorithm below (I'm not showin...
I was trying to erase some flash pages on an stm32g474re nucleo (and on a custom board with the stm32g474veh3).The flash pages are all on flash bank 2, because i read in the reference manual that flash bank 2 can be written while code is running from...
Hello,I make STM32G473 UART DMA work in debug trace mode (ST-LINK V3).when I disconnect wire and power off to reset for free run.it's not work.I don't understand.
Hi everyone,We are facing issues with USB in our new products due to EMC (electromagnetic compatibility). IEC61000-4-4 burst, mediuum severity.The USB stops working fequently when the device is connected to a PC and a burst is applied to the AC power...
I am not sure how to handle DMA channel from memory to peripheral. I have a circular buffer of 2*24 words that I want to load to PWM. I want to update(generate) new values once half and top of the buffer is reached. I was using similar thing for ADC ...
I am using the STM32f4-Discovery board, with the stm32f407vgt6 mcu. I am using it's USART peripherals at pins PB10 and PB11. Upon connecting another device to the USART communication something in the MCU failed, and now the board is not working prope...
Hello,I'm working with UART Communication between a RPi and an STMG070RB. For the UART communication I'm using the library function HAL_UART_Receive_DMA.I have an initialize in which the Receive function waits for 3 bytes to be received (My messagehe...
RM0316The reserved space is clearly indicated at the top, and the style changes abruptly on the next page, and the reserve is no longer specified. what is the result of missing addresses ? why can't a single style be maintained ? for clarity.
My Board is the STM32-G431KB Nucleo-32. I have a Mavlink Serial Tx/Rx (From a PX4 Autopilot) connected to PA10/PA9.I am attempting to receive serial data at 115200 8N1 on UART1 and then send it at the same rate on UART2. I am just doing a basic polli...
