Posted on August 17, 2016 at 14:53Hi, I have a stm32f405 on board connected to stlink v2. I am using both stm32 stlink utility 3.9 as well as stvp 3.3.8. When I erase/program sectors 0-3, all is fine. Sometime, I receive failure message on erasing...
Posted on August 17, 2016 at 12:59Hi,It is possible to start the bootloader directly for USART1 from application ?The problem is that the bootloader reconfigure pins that I need during the bootloader run.AN2606 shows in Figure 12 a procedure BL_USAR...
Posted on August 07, 2016 at 18:23Hi.Currently I use PA15 pin as external interrupt. The ISR routine is common for lines 10 through 15 and it is called EXTI15_10_IRQHandler. Now, I would like to have another signal connected to pin PB12, which has s...
Posted on June 21, 2016 at 13:55Hi everyone,I am working on a project and need to measure analog voltage on some channels. To do so I use CubeMx version 4.15.1, but the readings on channels are significantly different than the applied voltage (about...
Posted on August 15, 2016 at 07:22Hi,I am running a STM32L152 into stop mode. The MCU sleeps most of the time (waking up every 1hr to read sensors). As I have the watchdog running, I am using RTC to generate an alarm every 10s (watchdog period is ~2...
Posted on August 13, 2016 at 00:06Hi,I have a big problem where I seem to overload the AHB bus. The main components that are involved are SDRAM and LTDC. I am using one layer (at the same time) in svga resolution and the frame buffer is in SDRAM.Jus...
Posted on August 16, 2016 at 20:12Hi! I have a CS4344 DAC connected via I2S to my STM32F407, converting values at a rate of 44.1kHz. In parallel, I would like to convert values through the internal DAC, at the same rate, in a synchronized way (every...
Posted on August 16, 2016 at 18:09 Hi, I have the attached code. This is supposed to set up the ADC for 2 injected channels, 0 regular channels and DMA. Additionally, this is supposed to use TIM1_CH4 to trigger the conversion start of th...
Posted on August 08, 2016 at 22:39Hi, I just set up DAC output on the STM32F303 Discovery Board and I'm noticing a lot of wideband noise on the output (about .5 volts peak to peak), even when I set it to a constant value within my program. Is there ...
Posted on August 12, 2016 at 01:40dear all,I have studied the camera sample project, it uses dma from camera address to LCD memory address. I do not have lcd in my design, so when i run the camera project, i see one whole black image. Is there a way...
