Ambient noise level is not updating when in Detect mode
Howdy,I am currently working with a STM32U575 and currently having a problem with the ADF. I am trying to use the SAD to detect when someone is talking in the environment. When the MinNoiseLevel for the SAD is set to 0, the system remains locked in m...
Some Bootloader questions
I had a question regarding the bootloader, more specifically, the for the F429 variant. On app note AN2606, they list the embedded bootloaders. For the F42XXX and F43XXX variants, they list two different bootloader ID's. How do you know which one you...
Resolved! SPI as master and FPGA as slave for some bits
Hello everybody. I asking now for some help on my new project. On my stm32 u575zit-q i want send some bits, as master, on the FPGA EP2C5T144C8N as slave. This FPGA board is very simple (have no other peripherals on it). So i want send by means SPI, f...
PSSI and DMA issue
Hi,I am using PSSI on STM32H7R3 to transmit data with DE output signal and RDY input signal (flow control). Incoming clock frequency is 60MHz. Data buffer is located in AHBSRAM1 and have size 4096 bytes. GPDMA feeds PSSI buffer by 32bit access (four ...
Resolved! Multi Channel ADC with DMA on a NUCLEO H753ZIT6
I'm just getting started with STM32 microcontrollers and I have been using the NUCLEO H753ZIT6. I was trying to learn how to use multiple channels of ADC's with DMA. I was able to get some data when I used a single channel ADC normally. But now I'm n...
USB host issue in CDC mode
Hello everyone,I am developing firmware for the STM32F7508-DK discovery board, and I'm utilizing TouchGFX for the GUI aspect of the project. However, I am encountering a problem when enabling USB-FS HOST functionality. The GUI and other peripherals s...
STM32WB5MM CPU2 bootup issue if image of CPU1 is relocated
Hi,I am using stm32WB5MM, I have bootloader which is located on regular start address 0x8000000.Bootloader executes image which is located on some other location (location is divisible by 0x400 as required).For that image I changed linker file and xx...
Reduce Current consumption upto 3.8mA
Configured the controller stm32l151c8t6a to work in low power run mode ( UART peripheral running) but the current consumption is going upto 6.2mA. After disabling the uart peripheral the consumption decreases upto 4.2mA. In real situation we are goin...
Resolved! Incorrect SRAM2 and AHB1 Memory address in STM32F405/07xx Datasheet
In "Memory Mapping" section of the datasheet, the SRAM2 Address is indicated as 0x2001-C000. The actual Address should be 0x2000-C000 since from what the reference manual says, both SRAM1 and SRAM2 are mapped at 0x2000-0000. AHB1 Bus address has a...
