Hi, my goal was to play some .wav audio files from an external SD card using the onboard DAC and an Audio Booster XL Board from Texas instruments( BOOSTXL-AUDIO ). I was able to interface with the SD Card and read the audio files, but the problem cam...
Hello,I am interfacing with a sensor via I2C, with my STM32G0 MCU as the master. The sensor (Panasonic SN-GCJA5 air particulate sensor) requires a 500us delay between the I2C address read byte, and the data being read from that register: This is defi...
The ADC buffer is not being written to I would like it to zero all values less than 5 to eliminate noise. My project is a DTMF detector. I need it to pass through audio when no DTMF tone is detected and execute a command when there is one found. Also...
Hello. I am working on a project where I need to access an external Flash chip on a STM32H7A3ZIT6 chip. I am trying to use the FMC and I'm just having a hard time understanding it.My biggest lack of understanding is coming in how in the world do I pr...
Friends, which algorithm do you use to control the LEDs in this structure? I need your ideas. I have prepared a table of the LEDs' turn on order.
Hello, we have Custom PCB Board which Build's around Stm32F4 Series Micro Controller.In which we have Two USB Port, One Connected with External ULPI (High Speed 480mb/s) Another Connected with internal ULPI (full Speed 12mb/s). And we are U...
Using python I have written small app to convert SVD V1.4 into assembly include. Then I started to write assemby code using RM0492 Rev2 .For the peripherals I use (RCC,ADC,GPIO,GPDMA,TIM,USART) I have found that there are few errors in the SVD file, ...
I am trying to read multiple channels of ADC (like Temperature sensor channel, Vbat channel, Vrefint ...) using the interrupt method, but I am not able to read all the Channel readings , only the readings of first channel is being reflected for all t...
Hi, i'm using STM32U575ZI-Q (in NUCLEO-U575), I want to write and read Fat32 files on SD using SDMMC interface, with FileX middleware. When I set the bus width in 1-bit the app work OK but when I switch the setting to 4-bit buswidth mode the app cras...
I am having issues with my slave responding to my master. I am trying to lessen complexity by only using RXP on the slave, without TXP. The slave (Nucleo-H743ZI) responds one byte late.On the CS interrupt I send 0 for the first byte and enable RXP.*(...
