Posted on December 10, 2015 at 14:50Dear all, I am using a STM32F103VEH micro-processor. I intend to put the processor into sleep mode and configure it so it will wake up by receiving any interrupt. I use the following code: uint32_t tmpreg = 0; ...
Posted on December 10, 2015 at 15:28 Hello there, I have a logger application on a STM32F407 device. I am saving logs to sd card. Generally it works, but I would like to make the procedure a bit faster by opening the file only once at the beg...
Posted on December 09, 2015 at 19:15Hi I am writing some data to an external device on the address and data bus I have used Stm32cube to set up the timing data. Once I have written the data to the device I have to strobe a data line. This is fine bu...
Posted on September 29, 2015 at 22:32I've tried compiling the included ticker example with the STemWin_HelloWorld project included in STM32CubeF7. Functionally, it works OK but the draws seem to be corrupted. Take a look at the video I've uploaded o...
Posted on December 10, 2015 at 06:28I'm using STM32F4 discovery board and I'm receiving 38 bytes on UART RX line periodically, since I want to transfer this in DMA I used DMA circular mode. But according to equation DMA_SxNDTR = Multiple of ((Mburst...
Posted on December 09, 2015 at 11:50Hello,I have configured TIM1 as PWM source and enabled it. Its working becouse TIM1->CNT is incrementing and I have blinking LED based on value of TIM1->CNT. But now I need output it on PIN and its not workig. My ...
Posted on December 10, 2015 at 08:21I'm doing ADC and DAC on STM32F4 Discovery kit and suddenly, ''USB Device Not Recognized'' error pops up. Overcurrent LED (LD8) lights up and ST link error occurs. When I remove the Idd Jumper (JP1), PWR LED (LD2)...
Posted on July 08, 2015 at 13:50Does anyone know of a good delay function I could use with my STM32F4. I need delay in miliseconds and microseconds. #nano-delay() #ns-delay
Posted on December 09, 2015 at 20:10Hello, I thought about picking up firmware programming myself for a project I wish to create, however there is too much learning curve and I don't have full time to dedicate to learning and programming all of it,...
Posted on December 08, 2015 at 22:02Hi, According to AN4207 page 10, in Single ended zero ref mode the max input voltage to the ADC is Vref/gain. So if I set Vref = 3.3V = VCC, can I measure up to 6.6V with gain = 0.5? Or would this collide with the...
