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 have a Nucleo 144-pin F746ZG and I want to configure the user button (PC13, pulled to ground according to MB1137 schematic) to toggle an onboard LED on a falling edge via EXTI interrupt.I am using this sequence to initialize the interrupt handling:...
AN2606 Figure 115." Bootloader V9.x selection for STM32U595xx/99xx/A5xx/A9xx" show that the Bootloader USB detection aborts DFU startup to a system reset when no quarz is found. Does this abort also happen if an external HSE oscillator is used?
Hi, I've been trying to get an i2c connection working between two nucleo boards however nothing i have tried has worked. i am using the NUCLEO-H755ZI-Q and the NUCLEO-H723ZG both with i2c1 and on the same pins pb8(scl) and pb9(sba). for the H755 dual...
Hello, Hello,I purchased an STM32h7b3LI-DK demo board and I would like to have the source codeof the demo firmware installed on the board, is this possible?Best regardsSébastien
I'm using a custom board with an STM32U5F7. Written a program(with nothing else configured other than clock and FDCAN) that simply sends out a message via FDCAN (in classis mode, 500kbps) which I'm hoping to receive using a P-CAN. When probing the TX...
The sentence "Exposure to maximum rating conditions for extended periods may affect device reliability" is repeated:
We are using STM32WB55VGQ in one of our products. This product is a thermostat which reads temperature humidity along with 6 other sensor values and was installed in customer site. This unit was working fine for last few months untill last week when ...
Hello Tesla I need to run M4 from 0x08000000 and then M7 from 0x08100000. Is there any example ? Exactly I v'done my BOOT that runs on M4 (0x08000000) loads the Flash , then jumps into M4 (0x08040000). Now i have to run M7 from 0x08100000, but i d...
I need to generate a timestamp for data logging, but I'm not sure how to do it.The data packets are received via the UART at a 100ms rate and each packet of data consists of 10 bytes of serial dataByte 0: TemperatureByte 1: Voltage high byteByte 2: V...
I want tim16 to, every 1 second, start tim15 which is a oneshot timer which then does something when the period elapsed.I start tim16 in my main function, which works correctly, but the tim15 interrupt only triggers once, so my output looks like this...
