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 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 ...
Posted on June 28, 2018 at 16:01I am currently facing some problems with STM32F4, the process 'hangs' and I am not able to understand at what point it 'locked'. When this happened, I collected the following values for the following variables (I crea...
