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 28, 2018 at 20:48Hi,so I am using STM32F769xxx MCU with TI's CAN transreceiver (http://www.ti.com/lit/ds/symlink/sn65hvd232.pdf, see 232 version, the one without low power modes). I have 2 problems that may have something to do with e...
Posted on June 29, 2018 at 10:33I'm working at ARM Germany and using Keil MDK with the STM32L1xx_DFP pack v1.2.0According to the definition fromhttp://www2.st.com/content/ccc/resource/technical/document/reference_manual/cc/f9/93/b2/f0/82/42/57/CD002...
Posted on June 29, 2018 at 10:34Hello.I am using the STM32F334R8T7 in a design of a 3 phase buck converter.I have noticed that sometimes the HRTIM miss the reset event on the PWM (reset means put the output to 0).The frequency is 400kHz (0x2D00 load...
Posted on June 12, 2018 at 09:41Custom PCB using an STM32L031G6U6 (as a slave co-processor to a BLE module, to drive a graphics LCD display). We started with a Nucleo then migrated the project to a custom PCB which implements SWD directly and the pr...
Posted on June 26, 2018 at 14:32Hello all,I have cube 4.25.1 installed and I'm using stm32f303 mcu.What I have to do is to read 5 analog channels with ADC1 and 5 analog channel with ADC2 triggered from timer 4 counting.I read application note An3116...
Posted on June 28, 2018 at 15:32Dear colleagues,Could you please help to understand CAN 'bus-off' operational in a correct way? (can not find a proper description in the Reference manual for STM32F4).Some assumptions a) Suppose that ABOM bit in the ...
Posted on June 28, 2018 at 13:19I am trying to use BSP SD functions. One way to detect if SD card is inserted is with BSP_SD_IsDetected() and another way is via interrupts w/ BSP_SD_ITConfig() .The comments don't explicitly say which is the correct...
Posted on June 28, 2018 at 00:45I am now following a new path down the road with STM. I have done lots of work with old stuff like Rabbit Semi but just getting up to speed on ARM and someone at ARM gave me some very good recommendations on what I w...
Posted on June 21, 2018 at 05:51It appears, but is not clear from the data sheets, that the STM32F7 and some STM32F4's have two separate USB controllers a FS one and a HS one. Assuming suitable software can be created can these two controllers be us...
Posted on April 25, 2018 at 21:51Hi, In the SPI_FullDuplex_ComDMA example from STM32Cube_FW_H7_V1.2.0, if the aTxBuffer is changed from const uint8_t to uint8_t. (from flash to sram). The code below:for(i=0;i<128;i++) aTxBuffer[i] = 0x55;SCB_CleanDC...
