Posted on November 09, 2017 at 15:07Hi,i use a STM32L496.I configured the SPI to communicate 8bit but it always generates 16clk e 16bit data.SPI : MASTER- halfduplex 2wire(1clk , 1Mosi/Miso) /* Enable clock for SPI2 */ RCC->APB1ENR1 |= RCC_APB1ENR1_...
Posted on June 28, 2017 at 13:34Hello. My application hangs after setting the ROP to LVL1 and resetting the whole device. I have found some people had this issue as well and power cycling helped (which is my case as well). But it is kind of an incon...
Posted on November 10, 2017 at 14:09Hello, I'm working with STM32F4 Discovery Board and trying to generate a 16-pulse signal with variable duty cycle like this on the picture below.Currently i can generate 16 Pulse through One Pulse Mode. However i ...
Posted on November 10, 2017 at 07:40 Hello. I need read temperature from internal sensor. But when i use code from examples, all time i have result more then 30 degrees of Celsius(~1760 - factory calibration value, ~1740 - ADC value in cold st...
Posted on October 26, 2017 at 15:57I'm using STM32F0 Discovery and need to store values in SRAM when MCU is powered off.I already removed SB1 shunt. Then VBAT is not powered from VDD but pin3 of P1 (VBAT pin supplied with 3V).When I turn off my STM2...
