Hello, I am currently pretty stumped over the behaviour of the DMA triggered by a timer.I want to use the DMA to toggle a GPIO pin using a timer for the right frequency. I am currently using the DMA driver from Zephyr. MY board is the STM32G071RB.I w...
Hi,I have a custom board which has an STM32F446RE with implemented SPI peripheral that should communicate with MAX22530 chip. Currently, I am trying to test the SPI interface but am running into something that looks strange.The SPI ioc configuration ...
Is the internal bootloader on the STM32H723 DO-178 certified? It just dawned on me that the whole line of CPUs might be disqualified for aircraft use because the bootloader code "flies" with the aircraft and all such code must be certified to the l...
Hey all,I was just reading out the new release of the X-CUBE-Audio-Kit and it says:Configurable latency mode and audio buffer sizes adjustable down to fractions of millisecondsDoes anyone know the lowest latency that can be achieved?I'm looking to po...
Hi!I designed a shield for the Nucleo-144 (F429ZI) which provides power to the Nucleo-144 board through the E5V pin.To configure the board, I did the following:Place JP3 E5VRemove JP1Remove JP6Remove JP7Open SB169Close SB115I disconnected the ST Link...
I am working on touch detection with STM32L412cbt6 MCU. I am applying difference taking process in two channels of G1 and there are fluctuations in very small values (like between 0-100). When I look at the other group (i.e. G2), there are fluctuat...
Hello everyone. While studying the RTC module on the STM32F103, I encountered a strange behavior of interrupts from the RTC module.I configured two interrupts: every second - RTC_IRQn, and an interrupt on the alarm RTC_Alarm_IRQn. Additionally, I tri...
I have a test question about STM32G474 dual banks to ask :A test program for LED flashing has been successfully constructed in the IAR environment.Use STM32CubeProgrammer to load BANK1 starting from 0X8000000, DBANK=1,BFB2=0, and the program runs OKW...
Hi All,I have a system with 2 SPI masters and a single slave very similar to this post from 2014:https://community.st.com/t5/stm32-mcus-products/spi-multi-master-mode-with-stm32f050/td-p/502107What I would like to do is to temporarily isolate the STM...
I have a +30V -30V input to be fed to STM32H7 ADC 16-bitI tried using a 2 resistor potential divider using 33K 3.3K ; 1K 100E, 1M 100K, resistor combinations but the output is not correctly read by the ADC. (For 3V input, ADC reads from 2.2V to 3.2V ...
