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...
Posted on June 15, 2015 at 14:20Hello, I am trying to configure the SPI3 port of an STM32L151UC micro controller. I have tried several things but I see no output on the related pins. When using gpios instead of the AF of the SPI peripheral, I can ...
Posted on June 12, 2015 at 14:20I would like to connect to my car's CAN network but I'm a little confused as there are two CAN interfaces in STM32F407 - CAN1 (Master, PB8 and PB9) and CAN2 (Slave, PB5 and PB6). Why do we need two interfaces? Can you...
Posted on June 01, 2015 at 11:27 I made a project with stm32cude mx for stm32f401 discovery, discovery board is usb msc host, send a command to devide (usb msc device) then receive data form device my project connected and saw all infomati...
Posted on June 15, 2015 at 10:26Hi,I am using STM32F405.The NRST pin is connected to Vdd through a 100k pull-up resistor and to GND with a 0.1uF capacitor, just follows the design of STM32F4-Discovery. The NRST pin is also connected to GND with a 2-...
Posted on June 15, 2015 at 10:41 Hi, Using the cube 4.8.0 I configured PA2 to be GPIO_EXTI2 because I want an interrupt generated when the signal connected to that pin goes low but the code that gets generated for me looks like this: /*Configure G...
Posted on June 15, 2015 at 11:35Hello I've a question concerning the correct timings of center aligned PWM signals. Now it's pretty clear that usually when calculating timer bases one has to set the actual register to ''period - 1'' since the timer ...
