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 February 06, 2014 at 17:06I found a weir problem on me usb cdc connection. I have one cdc device and one cdc host. Every time I connected device to host, host looks like find another device (VID:0069h, PID:0063h) and stuck there. I have to...
Posted on February 06, 2014 at 16:35I am using cdc device to send message(32 byte length) to host with full speed. The message is send out every 1ms, while the host can only receive the message once around every 20ms second. Looks the speed is too s...
Posted on February 06, 2014 at 07:49I wrote a code to generate rising edge interrupts for a 4MHz clock input to the board. The 4MHz input is generated by MCO while the core is pushed to 168MHz. I found that certain interrupts are not being tacked at...
Posted on February 06, 2014 at 14:06 Hi, I need help with my Stm32F4 In this example I want to clock Tim4 with Tim2 using the slave mode. This is working fine! But when I want to use Tim4 to rise an update-interrupt this line stops the MCU. So...
Posted on February 05, 2014 at 18:41Hi All!I would like to use the STM32L152 Opamp output pin to pulse drive the MOC3020 optotriac.The pulse current should be ca 15mA-20mA for the optotriac to fire up under any temp. conditions.Can I source this a...
Posted on February 06, 2014 at 09:26Hello together, i´ve been searching for information about the minimal voltage wich has to applied to Vref-. In particularly it is around the stm32f103CBT6. I´ve used the search function in the RefManual, but co...
Posted on February 05, 2014 at 20:09Hi,how does the TIM behave if I perform a Disable/Enable sequence?Does it continue from where it were or will it restart from 0, (or ARR when downcounting)?/Peter
Posted on May 22, 2012 at 15:25Hello, I try to work with the UART4 RXNE interrupt but something went wrong. // USART2-TX, UART4-TX GPIO_StructInit(&GPIO_InitStructure); GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF; GPIO_InitStructure...
Posted on February 05, 2014 at 23:54 I have just implementet a Low Speed Internal (LSI) oscillator calibration using a timer connected to the High Speed External (HSI) crystal. Right after I enabled the timer interrupt (and probably interrupt fi...
