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...
I'm using the arm_rfft_fast_f32 function, I write a scatter file and place some library files in the CCM SRAM like below, and the speed is faster. RW_IRAM2 0x10000000 0x00002800 { ; CCM SRAM 10kB .ANY (ccmram) arm_rfft_fast_f32.o (+RO) arm_cfft_f3...
I can't seem to get the multiplexer to initialize each display and such nothing is being displayed. Could anyone help?
I want to ask for serial line is there any limitation os using DMA transfer for slow periodc data??Thanks in advance for any help.
Hi,I am using STM32L0 MCUI am using HAL_USART_TRANSMIT function to send data to a computerI am using Timer interrupt to ensure that UART transmits data every secondBut when i see log on computer ,its not exactly 1 sec, and this change also varies wit...
I am using the stm32f103 and trying to display a text on a screen via DMA to the USART 2 device. I guess I will turn on the usart2 TX dma (DMAT) request when I need it and turn it off after the current transmission is complete (i.e. in the DMA1_Chann...
as I proposed some time ago, now products->Mikrocontrollers->Resources lists also datasheets. That way, one does not have to check the individual product pages for datasheet updates.Some other proposal however is still pending:List the documents newe...
I've searched through the internet but i'm not able to find any firmware or source for coding the STWBC, atleast a few examples on how to do it. STM provides a binary as firmware to download and use it directly on the evaluation board. But i want to ...
I'm having a problem where I'm controlling 9 LEDs with timers. Whenever I enter stand-by mode, the LEDs turn on/stay on. I want them to turn off. I can shut them down before stand-by mode but as I enter, they turn on. I've tried switching timers in...
Hello,I'm struggling to get the SPI Slave on my STM32F4 running. I send 9 Byte from the master every 1ms with soft NSS: HAL_GPIO_WritePin( MCU_CS_GPIO_Port, MCU_CS_Pin, GPIO_PIN_RESET ); SPISlaveTXdata[0] = frameCounter++; SPISlaveTXdata[1] = sys_g...
