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...
HiMany CAN messages are flowing on the CAN bus.I would like to receive only ID 0x5C0 among these.Please let me know the suitable settings to receive only 0x5C0 as a hardware filter without any software intervention, without any load on the MCU.I wrot...
Our product uses a STM32L452 to measure the 4-20mA loop current of an external sensor. The product has an operating temperature range of 0-40°C.The STM32L452 datasheet (Tables 78 to 82) lays out the accuracy specs for the internal ADC but aside from ...
Posted on July 15, 2018 at 02:10Hi.I am doing well. The Panasys 3.4' round TFT (actually it's about 2.4' round, in an octagon, that was probably cut from a 3.4' square once upon a time) MIPI DSI display is working on the stm32l4r9i-discovery, after ...
Hi. I'm using STM32F446RET6 and F401RE, and I enjoy coding with those. I majorly use my desktop PC to develop. But for a long time, my laptop PC can't recognize my ST micro computer. So I can't develop with my laptop. Then I tried to upgrade ST-link....
Hello ! I've been wondering how DMA works in UART. I've checked some codes for example HAL_UART_Transmit_DMA(). I know it is set to sned 8 bit to peripheral. But I wondered when DMA knows that UART sent 8 bit when it is TX DMA or recevied 8 bit when ...
I'm doing a project where I want to have a toy say audio clips when a button is pressed. Right now I'm trying to accomplish this with an STM32F407G-DISC1. I have a small speaker (16 ohms, 0.25 W) connected to my breadboard with the DAC OUT1 of the MC...
Hello Community,given is this circuit:Typically when I use external pullup circuitry for a signal I set the corresponding GPIO to "Open Drain" and no pullup/-down as the state of the line is defined externally.Flash_CSn is directly connected to PB4 o...
I.want to know the use of series resistance that is placed with STM32H750B-DK and External RAM , And also.with it's Dual Quad SPI interface.Is it possible to leave them as it is or it is compulsory to implement.
What is the best way to use sscanf with uint8_t?When I use: uint8_t x ; char* y = "23" ; sscanf ( y , "%hhu" , &x ) ;I stuck at: void HardFault_Handler(void) I found following workaround that works: uint16_t x1 ; uint8_t x2 ; const char* y ...
hi i would like to use uart1_printf_debug debugging on a serial terminal but error message "undefine reference to "uart1_printf_debug" what file to include except stdio.h?
