Posted on May 20, 2018 at 21:28 On an STM32F103 nucleo board I occasionally find my program locked in a loop waiting for the SPI2's BSY bit to become cleared. I am, honestly, totally clueless what is happening here. I am hardly able to track d...
Posted on May 16, 2018 at 10:46Hello,I have STM32F7 discovery kit (Discovery kit with STM32F746NG MCU) . I have successfully tested microSDCard withKeil + STM32Cube able to Create/read/Write txt files.I have also through UM1721 'Developing Applicati...

Posted on May 18, 2018 at 12:11Hello ,I am toggling a gpio inside the timer ISR . the timer ISR triggers for every 1 sec. Actually i am not able to see perfect 1 sec of gpio toggling . it also differs at different AHB frequency . i have included 2 c...
Posted on May 19, 2018 at 16:21So, I am using STM32F769xxx to run MIPI-DSI display. On the display's datasheet there are power on and off sequences. I am able to get display on and off (so commands are at least somewhat OK), but colors and data on l...
Posted on June 02, 2017 at 09:41Hello , I'm a trainee and my project is to migrate from stmf4xx to stm32f7xx , so i was compile the all project using stmf7xx library on keil uvison 5 ,and fix all error due to incompatibility of these two microcont...
Posted on May 19, 2018 at 06:04Hi !I am using STM32L4R7ZIT6-144 Pin LQFP Package on Keil-MDK, So far all other GPIO ports SET/REST test is normal except Port G with its associated SPI configuration which is neither getting SET nor RESET on push pull...
Posted on May 18, 2018 at 00:53Dear all,I have question regarding the VREF+ please. My understanding is that in STM32L we only have one VREFINT which is about 1.2xx Volts and this is not a reference Voltage to the ADC. It is directly connected to ...
Posted on May 18, 2018 at 22:27What is the purpose of Left and Right Alignment of data in DAC?Secondly, In DAC_DHR12L1 do we need to manually shift the bits to the left to get them to right place or does it happen automatically?#dac #stm32f103rb
