Hi,The ILI9341 display https://cdn-shop.adafruit.com/datasheets/ILI9341.pdfas on Page #35/233, is it using SPI MODE:3 ? Can someone clarify ?Slightly confused with the timing diagram for the 4 line Serial interface and hence my question.I am trying t...
I understand AXI and AHB have limitation that burst transfers cannot cross 4k/1k boundary.I can see this explained with DMA1/DMA2, but not with MDMA. Are you still required tofollow this rule with MDMA ?The other question that puzzles me: is it requi...
ie: due to 1st request: dont finish a full PWM cycle, but make the PWM think that the cycle will end at the time that OUT was forced to low+ duty low time (shortening the cycle time).1st request was easy: I've connected COMP to TIM2_ETR.2nd request...
Hi community, I'm searching a USART example , STM32F407VETFirst, I create code by using STM32CubeMX. I has try it but it is too hard to use that. I felt 'HAL UART' example of length of the array that receive and send , has limited. (or need more b...
Hello,We are struggling for a while with bank2 access in continuous clock.We are using FPGA connected to bank2 in FMC bus.We work with FIFO access in FPGA (a single address for the FIFO)Single register access works fine, but with burst access there a...
i am using stm32L072I am using uart1 in the code I found that code doesn't works ,if i don't connect a usb to uart converter between PC and the microcontroller .When i connect usb to uart connector and reset microcontroller ,it starts working :wear...
Hi Community, I'm studying about the android program and stm32f407vet based controller.The question I asked before is almost clear by using DMA USART.I'm Transmit and Receive like under code.code(IN STM32)uint8_t rxBuffer;int SIZE_OF_RX_TX = 1;if (...
I want to build a giant LED display that will scroll messages. I hope to add effects to the messages. I can't seem to find any library for STM products. And can someone give me a guide on how to create a custom LED library as well. Thanks
Dear experts,I'm struggling with a strange TIM6 interrupt issue on STM32H753I.Playing with one of Cube example projects with FreeRTOS, where TIM6 is used as HAL timer.The original IRQ handler is very simple (and the demo works fine) :void TIM6_DAC_IR...
