Posted on March 08, 2017 at 11:54Im trying to read a battery voltage with a STM32L152, using timer 2 to trigger the ADC. I can see Timer 2 running (by toggling a LED in the TMR2 interrupt routine) but my ADC only reads once (when the circuit initia...
Posted on March 08, 2017 at 02:42Hi! I got a problem when I was dealing with ADC. I am wondering if I need to use the multichannel at different time, which means I want to start one channel at a time and get a thousand ADC data then stop ADC,after ...
Posted on February 26, 2017 at 12:32Hi everybody,I am facing a rather strange problem when trying to program the two user option bytes (0x1ffff804, 0x1ffff806).The code I am using is rather straightforward: volatile FLASH_Status test3; volatil...
Posted on January 18, 2017 at 12:52I'm working on project involving STM32F746 in QFP208 package.Reference manual states that in Legacy SPI mode (which may be used for compatibility purposes) pins are configured as:• IO2 is in output mode and forc...
Posted on March 10, 2017 at 14:46Hi,Continuing my saga on SPI DMA, which works now.The idea is to use it to drive a SPI LCD, an ILI9341 with DMA.I see that I can communicate with the LCD, but all 16 bit writes are messed up due to SPI write with 16 ...
Posted on March 12, 2017 at 14:08The data sheet of the STM32F429 shows that its camera interface can take 14-bit parallel data and the maximum data rate is 54MB/s. Also it says the interface supports 8-bit progressive video monochrome or raw bayer f...
Posted on March 10, 2017 at 15:46I'm trying to use timer2 ch2 for input capture, but I don't seem to get it to work.I wonder what am I doing wrong?I don't use CMSIS or any other libraries.Here's my set-up: nvic[NVIC_ICER_0] |= 0x10000000; // disa...
Posted on November 06, 2016 at 23:11Hey guys, I used CubeMX to generate a setupcode for my STM32F4 Discovery board. When I began my work, i noticed that the FreeRTOS Version used by Cube MX is an old one. Do you know when V9 would be supported by Cu...

Posted on March 11, 2017 at 12:00Hello.I am working on a project where i collect the external ADC results through the I2S peripheral (using double buffer DMA).The algorithm works in the following way:- Once memory 0 is filled, interrupt occurs, a fl...
