The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on February 28, 2017 at 22:28Hello! I have a problem with using usart transmit function twice in main program on STM32F4/STM32F0. First transmition should be with DMA and after it data should be send in blocking mode without using DMA. Proble...
Posted on March 09, 2017 at 06:01Hi I am working on STM32F769i-Eval board.I am connecting analog camera with CVBS output to ADV7180 chip.Output of ADV7180 is YCbCr and provided to MCU as input.MCU accepts YCbCr data but to display on the LCD i need ...
Posted on March 09, 2017 at 04:08HI,i found that some peripheral can select clock source by change RCC_CCIPR.but both ADC and CLK48M,default clock source is ''No clock selected'',it can work normal also.why?
Posted on March 08, 2017 at 23:45We have a device which is self powered USB peripheral, using the ST provided USB stack, I'm seeing the device fail to detect the loss of VBUS (notified via the SEDET interrupt). It works approximately 70% of the time...
Posted on March 07, 2017 at 11:40When looking for QFP32 part with > 64 kiB, the MCU Finder brings up STM32L0[7|8]2KZT. However the web page of these parts shows no distributor availability. Can we expect these parts available anytime (soon)?
Posted on March 08, 2017 at 17:57Hello!From a cursory glance at the datasheet it seems like there are many pin conflicts between DCMI and FMC on the F7. Does that mean they cannot be used at the same time?Isn't that a bit of an oversight, considerin...
Posted on March 07, 2017 at 21:16Hi,Here is my transmission code:void USART1_IRQHandler(void){ if (USART_GetITStatus(USART1, USART_IT_TXE) != RESET){ if(Counter<=65 && TX==1){ if(MESSAGE[Counter]=='\0'){ USART_ITConfig(...
Posted on March 06, 2017 at 18:38Hi, I have a problem when I try to load my program. I use the arm compiler (armcc) with a stm32l073.When I use my debugger I have an Hard Fault handler every times before the main.I use a standard statup file (startu...
Posted on March 08, 2017 at 12:11Hi,i have a little project working on stm32f415, with a task producer and a task consumer, between i want put a SdCard ( with fat ) like cache, because if something going wrong during trasmission or consumer is busy ...
Posted on March 07, 2017 at 02:29Hi,I'd like to use 3 USART DMAs on STM32F405.If I use only 1 USART DMA, it works well.But if I initialize 3 USART DMA in 1 workspace, only the last one works.Below are my configurations.#define USARTx USART2#define U...
