Hello everyone, im currently studying DMA on STM boards, and im trying to send I2C messages from a mcu SLAVE (arduino) to STM32F407VET6 master, but both SCL and SDA lines is held low, it doesn´t happen when im using I2C in polling or interrupt mode, ...
Hello,I would like to know the process size used in the STM32G4xx. I understand the 'F4, L4 and G0 are 90 nm and the 'H7 is 40nm. My interest stems from an application in a high RF environment, where larger process size would seem to be more robust...
Trying to receive data on MCU (L432KC) configured as SPI slave. I have tried using interrupt and DMA, but no luck. I have set up the circuit like this : 1 MCU acts as master sending 1,2,3 every 500ms interval (I hooked up master lines to scope and th...
I'm using an STM32F407 MCU with a 600 PPR incremental optical encoder. The encoder is coupled to a stepper motor that drives a 5mm pitch ballscrew. I'm trying to keep track of the encoder count to determine the absolute position of the spindle attach...
In STM32F7 dual/single bank configuration is available. It can be done using nDBANK bit of FLASH_OPTCR register. Ref link: https://www.st.com/resource/en/application_note/dm00266999-stm32f7-series-flash-memory-dual-bank-mode-stmicroelectronics.pdfFor...
Hello guys.Eventually I have to learn how to use CMSIS my self to create my own code instead of using CUBE.There was alot of examples for everything in CUBE,but I cant find examples written in CMSIS.Can someone help me finding them?The other question...
Hi, Im a newbie to ZEPHR and would like to test the ADC feature, I just want to be able to read the voltage level on an I/O pin. I have been unable to find sample code. Any help would be appreciated.
hi any one now how can used arm fir filer high pass filter i need high pass filter adc input for 500khz and seprated 500khz wave add on 100khzi used q31
I'm slowly learning how to use the STM32 family starting with the STM32L4R9-Discovery board. I use mostly VisualGDB and have run and modified a variety of UART examples and FATFs/uSD card examples. When I try to put them together so I can log data on...
I connect STM32F429 with an eMMC NAND via SDIO interface(CLK CMD & DAT0).This initialization sequence for eMMC should be CMD0, CMD1(wait OCR bit31), CMD2, CMD3, CMD9, .....The eMMC driver is tested ok on STM32F103 system, including init, read, writ...
