Posted on December 15, 2016 at 22:59I have a STM32L152 device which spends most of its time in STOP mode, waking perhaps once an hour. I'd like to add IWDG support, but need to 'freeze' the IWDG during STOP mode, which per STM docs can be done.I hav...
Posted on November 28, 2016 at 17:27Hi,I am a newbie developer on stm32 and iar.I have a simple question about spi DMA. I use a stm32f412 mcu as a SPI slave device,when the DMA controller on the stm32 mcu is starting to move data from tx buffer to s...
Posted on December 16, 2016 at 13:26Hello,I am trying to erase a flash page in Bank 2 of STM32L071RZ and it instead erases the 1st page of Bank 1( where interrupt vector table is stored). The code is fine as the same works very well when the page ad...
Posted on December 15, 2016 at 23:38Just wanted to mention a small bug in CubeMX 4.18.0. I am using STM32F446ZET. It has two I2S peripherals. When I configure I2S1 in the Pinout tab, the Clock tab shows the clocks wired for I2S2. And vice versa. The...
