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 July 25, 2016 at 13:54Hi. I have problem with finding interrupt subroutine which Is called when DAC DMA underrun interrupt event happen. There isn't any DAC IRQ in which I can check status like this: if(DAC_GetITStatus(DAC_Channel_1, DAC_I...
Posted on July 25, 2016 at 16:20Hello all,I am using both CAN on my device. It is all working well except that I am receiving in HAL_CAN_RxCpltCallback() an incorrect ID value for all my CAN2 filters. I have 6 filters on CAN1 from 0 to 5 and 6 fil...
Posted on July 25, 2016 at 03:50I know that I2C's official speed is 100KHz (Standard Mode), 400KHz (Fast Mode), 1MHz (Fast Mode Plus).But, in my lab application, I need to implement 4MHz I2C signal. I had used FPGA logics to achieve 4MHz I2C signal....
Posted on July 15, 2016 at 16:13Hello,I have a scenario as follows: I have a Timer 2 that gets interrupted every 1ms. I try to communicate (only Tx) with an external device every 50ms by calling a function inside Timer 2. When the system is running ...
Posted on July 25, 2016 at 14:46Hello, I'm trying to find out how UART received data is influenced by noise. STM32F1xx reference manual states that the UART will check three sampled values from the middle of each bit. If one of those three values di...
Posted on July 25, 2016 at 14:15Hello, STM32F0 are my favourite ARM based 32bit MCU. Now I have a design of disel engine control unit for cars and gensets. So we need automotive grade MCU. I am trying hard to find one. But I think not available from...
Posted on July 17, 2016 at 17:13Hi, I just got a Nucleo STM32L031K6 board and start playing with STM32Cubemx. For my project I need to use the low power timer LPTIM to trigger another timer (e.g. TIM2) but I have no clue how to do this. Could someo...
