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...

Posted on June 27, 2018 at 13:25Hello,I am new in timer implementation , I want to generate PWM timer with an external clock using 2 MHz as frequency.. It shall be possible to enable or disable the generation of the PWM signal. I can able to generat...
Posted on June 27, 2018 at 16:02Hi folks,I have been RTC on STM32F1 for a very long time. I have been using the RTC seconds counter (and subsecond counter) to calibrate RTC continuously (i.e. every day) on-the fly against a reference time (derived ...
