I am designing right now using STM32051. Using the only SPI interface for my project, I am struggling how to use the NSS for two slave, that the chip give me only one NSS.It is possible to load my Programm to the chip using the RS485? How could I rea...
Designing a touch sensor is not an easy task. The touch sensor front panel you choose is more important than you think.In touch sensor design there is a high level of complexity and many design choices to consider. Complex physical phenomena and cost...
Hello.When I loaded the array into Flash (used const) It was displayed on the screenBut as soon as I use RAM to store the image it stops displaying, I see a black squareI also can not fill the color programmatically LTDC just does not react
Hi,I'm trying to send data via UART6 TX DMA on STM32F429-Discovery board. All is well, if I send packets of size less than 16 bytes (FIFO buffer size). However, if packet size is larger than 16 bytes, only first 16 are sent and the rest of the data i...
HiI am currently working on stm32f407vg discovery board. I have written code for stm32f407vg in Atollic True studio. But when i connect stm32f407vg discovery board to external source (power bank), built in leds (orange(LD3),green(LD4),red(LD5),blue(L...
Hi All,I use STM32f103C8T6 mcu to control a 5" TFT (480x272) display in direct mode.TIM1 PWM is the 9Mhz pixel clock,TIM2 is the column counter,TIM3 is the row counterand TIM2 channel 2 in compare mode, start SPI DMA transmit once in lineso, the SPI ...
Posted on April 25, 2014 at 12:56Created a project targeting STM32F4DISCOVERY + STM32F4DIS-BB from a scratch with CubeMX. Managed to blink LEDs and send bytes over UART but now struggling with Ethernet and LwIP. I have referenced STM32F4DIS-BB examp...
Posted on July 11, 2017 at 09:32Hi,I'm using Stop mode on a custom board with STM32F207. There is a SRAM on the board for data storage.I turn off SRAM in Stop mode, to reduce power consumption. Now I want to disable the FSMC of SRAM too. Therefore I...
Hello For the STM32H7 micro controllers what does a "SRAM with scattered architecture mean". "The STM32H7x3 line provides from 1 to 2 Mbytes of Flash memory, 1 Mbyte of SRAM with a scattered architecture: 192 Kbytes of TCM RAM (including 64 Kbytes of...
Hi,I'm having a hard time configuring the system clock. It seems that I'm achieving 16MHz, but I want to run at full speed (216MHz). From what I'm seeing, the problem is that the System Clock Switch isn't changing to PLL. If I try to change bits 1:0 ...
