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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on June 29, 2016 at 15:58I am seeing an issue on the STM32F207 where if an I2C transfer fails the TxE bit is never cleared, causing the I2C2_EV_IRQHandler( ) to continuously get invoked and the overall system to hang. I know this isn't a lot ...
Posted on April 22, 2015 at 23:27 A recurring big problem with CubeMX (all versions. using v4.7/latest now).... After making pin mapping and peripheral config changes, I run GENERATE CODE, as often I do. Too often I get this from CubeMX: ''The Code ...
Posted on July 20, 2016 at 15:31Hello, I use STM32L1xx ADC in scan mode with DMA with these settings: ADC_CR1_SCAN set ADC_CR2_CONT cleared ADC_CR2_DDS and ADC_CR2_DMA set ADC_CR2_EOCS cleared I scan 4 channels after trigerering with ADC_CR2_SWSTART...

Posted on July 25, 2016 at 19:21 Hello, I am using CubeMx to generate 1-bit SDIO SD card code. I have done so much programming using CubeMx and all those codes workfine. But When I generate SD code it is giving error (Hard Fault) at the func...
Posted on July 18, 2016 at 16:39Hi,In STM32F373-EVAL board,SDADC is used to measure temperature with PT100 as sensor.The circuit is showed below.These two pictures are screenshots of tutorials of STM32F373-EVAL board.The document says the gain of op...
Posted on July 25, 2016 at 23:20 Hello, trying to generate 1 millisecond interrupt using TIM4 timer with in STM32F103 series of processor. By selectinghtim4.Init.Period = 1 able to generate Two millisecond interrupt. When we configurehtim4.Init.P...
Posted on July 25, 2016 at 01:25Hi, Using cubeMX I have implemented a timer triggered (42KHz T2 TIM_TRGO_UPDATE )circular DMA transfer from ADC channel 1 to memory buffer. I am trying to do some audio processing in real time. Also I am driving ...
Posted on July 25, 2016 at 14:34When we setup a GPIO pin for Alternate function, their is only option for Alternate function output. Even if some alternate functions are actually input to the peripheral (like USART_RX, Timer Capture Input etc). Even...
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...
