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...
Posted on March 08, 2017 at 16:17Recently I started using STM32F401 as an application chip together with nRF52 for BLE connectivity. This required some parts of nRF52 SDK to be ported for STM32. However, I had some problems with software interrupts ...
Posted on March 07, 2017 at 06:32I'm planning to power the board up via external power supply. After looking at its schematic diagram, I found that one can supply power through 5V pin or 3V pin on the headers. But I wonder if you could have problem,...
Posted on March 07, 2017 at 05:00How do I change the IAR linker in order to move the stack and heap to CCM? I am using STM32F407.
