Posted on December 15, 2015 at 10:05 I'm using STM32F4 Discovery. I configured a GPIO pin PB8 for external interupt for both rising and falling edges, so that I have to reset a flag when it is high->low or set when low->high which is done by rea...

Posted on December 10, 2015 at 06:28I'm using STM32F4 discovery board and I'm receiving 38 bytes on UART RX line periodically, since I want to transfer this in DMA I used DMA circular mode. But according to equation DMA_SxNDTR = Multiple of ((Mburst...

Posted on December 03, 2015 at 14:38I will be receiving 10 bytes on UART RX periodically and I want to configure UART RX DMA for it. Configuring DMA is like loading the NDTR register with the number of bytes to transfer from/to peripheral to/from me...

Posted on November 18, 2015 at 08:18Hi 1. Can a UART receive interrupt wake the STM32 MCU from Stop mode (RX line start bit) ? 2. Only a External Interrupt can wake the STM32 MCU from low power modes ? Regards #!stm32f4-disco #low-power-stop-mode

Posted on October 14, 2015 at 06:59 Hi I want to know whether there is penalty on accessing an array from a structure vs accessing by a simple array. Here is my snippet which i used when I faced the problem unsigned char array_1[102...
