Posted on May 20, 2018 at 13:57Like many before, I'm trying to receive data with variable length, in particular responses from an ESP8266.My idea is to look into the stream of received bytes to find an occurrence of 'OK' or 'ERROR'. My first versio...
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 ...
