Posted on July 01, 2015 at 01:16 Existing code, ADC2_IN1 on PA1 works polled 100 numbers vary from 150 to 3050 sinusoid. HW guy added ADC3_IN2 on PA2. Changed the code as below, but 100 numbers are all between 3013 and 3015, although can see a clip...
Posted on July 06, 2015 at 21:56 I am testing/playing with a STM32f207 dev. board. I would like to know what ways are there to get most out of the ADC converter. For instance, is it possible to shut down the rest of CPU when conversion is done. ...
Posted on July 06, 2015 at 08:32Hi guys, I have been programming with Arduino, however, it seems that I need something more powerful. So I started doing some research and I am particularly interested in STM32. The problem is, the learning curve is ...
Posted on March 02, 2015 at 08:44I've test the STM32F072 for using it in a new project. The configuration and libbrary are used from the CubeMX with the Keil compiler.Now I can maximum transmit 4 bytes over the UART with one DMA transfer.main.c atta...
Posted on July 06, 2015 at 18:18I am trying to use the SPI interface with a SPI temperature sensor and the STM32L Discovery board. I want to make a very basic read operation. I have set SPI_CLK to PA5 , MISO to PA11 and MOSI to PA12. The CS is contr...
