I like to use SPI in continous DMA mode together with a SPI-slave that uses the falling-edge of the spi clock (AS5048A: https://ams-osram.com/products/sensor-solutions/position-sensors/ams-as5048a-high-resolution-position-sensor). So, I have to use C...
Hello, I'm using Nucleo H723ZG.In my project, i need to detect a rising edge to trigger a callback. What i have done is that i setup a GPIO as external interrupt, and i verified the code by manually connecting and releasing from 3v3 pin. The actual s...
Split from this thread. Thank you for your previous responses and guidance. We are now planning to move to the STM32H750XBH6 (BGA package) with a 32-bit SDRAM (IS42S32400J-6TLSDRAM ) interface in our custom board design.Our project uses a 12.1-inch d...
Hello stm community. I am working on a project involving STM32H7 series MCU with Raw LCD panel of 24 bits. Since the display has no IC i am using the internal LTDC component to drive the lcd. So i have some questions can i drive the lcd backlight wit...
Hello,another day, another N6 "issue" :)I want to do RAM to RAM copy by HPDMA, but the data never get copied from Src to Dest, Dest always stays unmodified. I have checked the 'DMA_RAMToRAM' example for N6 and went from there, but with no success.DMA...
I'm looking for an ST microcontroller that can do I2S receiving while remaining low power, presumably by keeping the core asleep and using DMA to copy I2S chunks to a buffer. I think I saw a video demo of this at some point somewhere on the website, ...
When using SPI6 in Slave mode with TX DMA in Circular mode, the SPI FIFO is not updated with data from the DMA buffer for the first SPI FIFO size (8 bytes). Both the SPI Master and SPI Slave were debugged: The SPI Master transmits one frame. On ...
Hi all,Im using STM32F410 uart 1 to transmit and receive.I use DMA to transmit bytes. I then use TC interrupt to send a break,then push an event to an event queue to signal that the transmitter is free.void interface_uart_tx_eot_isr(if_uart_t* p) { ...
We are using the STM32H7R7L8H6H microcontroller in our product design.During firmware initialization, we observed inconsistent behavior related to the USB voltage detector on different boards that share the same hardware design and firmware.Specifica...
Being fairly new to the STM32 architecture I find the following statement in the STM32F103 reference manual really confusing ... "..., this means that only one request must be enabled at a time." (the same also applies to the DMA2 controller). I thin...
