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...
Would we use the RS485 to the encoder ?
Oddly the on board NFETS are rated 60v, why only 20v input? Can we safely go to +48vdc, if not why? Our motor driven FW the voltage does not go above Vbus.Is FOC space vector 7 phase or 5 phase switched? Thanks
