I was working with SPI dma transmision. I config two channels for transmit and receive, however I didn't enable interrupt option in dma, however, before each transmision I cleared tc flag, and then enable spi while polling the tc flag. This works rea...
Use two NUCLEO-H743ZI boards for SPI communication. Full-duplex DMA mode. When the baud rate is 25M, the master and the slave can receive the data correctly. At 50M and 100M, the slave can receive the data correctly, but the master cannot receive the...
Hello, In India, the STM32F407 discovery board is out of stock. I enquired many vendors like element14, Digikey and other locals, it's not at all available. Did ST stop the production of this ? Will it be availabel in the future ? which is the close ...
Hello there.Our design currently utilizes MDMA for intensive writes from SRAM4 to FMC bus area. Transfer is setup with double word transactions, witch is critical for performance. DMA 1/2 or BDMA is simply do not cut it due to lack of AXI access i gu...
The document AN2867 (Oscillator design guide for STM8AF/AL/S, STM32 MCUs and MPUs) defines to groups for the F4 series: F4_g1 and F4_g2. There is a list with the controllers for each group, but the STM32F413 is not mentioned.
Hi,Can someone help me identify what I am doing wrong ?Still having issues with the DMA, but with Rx DMA instead. The issue with Tx DMA is fixed.I am trying to send 4 chars from a terminal to the H743 rxbuf array using DMA.In the debugger window, the...
Hi, There is a feature provided by ST in the L475 controller that Modbus/RTU communication using USART. Can we ignore the USART RX interrupt as the end of block detection interrupt provided by this feature to collect the data?Is this block detection ...
I am trying to catch levels out of threshold using ADC and analog watchdog on NUCLEO-L552ZE-Q. Unfortunately analog watchdog fires interrupt even when value is within the guarded range. I came across this example: https://community.st.com/s/article/h...
I've been trying to get simultaneous RX and TX working on USART2 of a STM32L073 and have not been able to get it to work. I've messed around with priorities, order of enabling DMA transfers, etc but always the TX DMA transfer succeedes and the Rx DM...
I'm evaluating the STM32U585 TLS performance using the eval board B-U585I-IOT02A. The example application code for MQTT using TLS did not include code on how to load a client key for client authentication but I was able to add that in. The problem I ...
