Posted on July 10, 2015 at 11:34I am planning to program stm32f103 micro controller over the air. I have a sim808 module connected for network connections. Any new firmware changes needs to be pushed to the microcontroller via sim808. Can this be ac...
Posted on January 23, 2017 at 07:43Hi,I am trying to use a TFT with ILI9488 via SPI. The Display works but it is incredibly slow. What am I doing wrong ?I am using FreeRTOS and LWip in my project, too.It would be great to get a hint or two.ThanksMar...
Posted on January 31, 2017 at 23:25I want to synchronize micros that each have their own clock. Is that possible? I was thinking of having a Master control the synchronization with GPIO. Essentially, when the pin is high (or low), you start whatever...

Posted on January 31, 2017 at 17:00Hi,I'm having no problem using the DMA in basic functionality, but I've run into something I can't figure out by my self.I'm having a STM32F207 processor and try to use SPI2 at the same time as UART4.the TX interr...
Posted on January 31, 2017 at 18:19I am using an STM32 F437 processor and the broken code I inherited uses the DMA to handle traffic from UART8. I am still grasping at straws a bit trying to find the best sources of information. So I am hoping someo...

Posted on January 31, 2017 at 16:57Hello,page 153 tells:8.4.1 GPIO port mode register (GPIOx_MODER) (x = A..E and H) Address offset: 0x00 Reset values: · 0x0C00 0000 for port AThis does not make sense and a look at a real device after reset gives:(...
Posted on January 31, 2017 at 15:56Hi All,I'm working with a board with two STM32F7 processors and trying to connector to the built in bootloader on one from the other via USART. The TX/RX lines are connected to the target on USART3 and on the maste...
Posted on January 31, 2017 at 15:52Hello!I have a basic question about the association between WKUP and EXTI signals in a STM32. I am using a STM32L467.My system has a push button that I want to use to wake the mcu from the STANDBY power mode. I als...
