how to check the watch dog timer?
I'm using watch dog timer with STM32F103C8T6. how i check watch dog timer is working or not working.
TIM1 (Input Capture Mode) should DMA one single input Capture value (direct time period measurement, counter reset at every capture) to Memory at every TIM15 counter expiry.
Hello, I want to trigger TIM1 (Input Capture Mode) using TIM15 counter elapse (say every 1 sec). TIM1 should measure input frequency , reset counter every capture, and do one DMA of Input capture value to Memory buffer at every 1 sec (say). I tried P...
Resolved! Detailed programming reference for specific boards?
Are there register programming references for specific boards?Its really confusing when there are a whole bunch of "STM32" cpus, that i would think should share common register offsets, but STM32F4 has completely different offsets from STM32L4, for e...
Driver for adrv9003
Hey everyone, I tried to write a driver for adrv9003.I tried to do it with stm32h7 controller.So, I tried to use no-os repository from github, and I generated main code with ADRV9001 Transceiver Evaluation Software.I remove the fpga member from initi...
We have to purchase electronic components from China Market.(Shen Zhen) China market price is so cheap compare to others. So there is concern about authenticity. Can anyone confirm ?
ST components ( Made in China) from China market(Shen Zhen) are authentic andqulify or not ?Last year we bought STM32F030K6T6 500 pcs at the price of 4.2CNY/pcs.(~0.62USD)And a few thousands of STP75NF75 at 2.4CNY/pcs.(~0.35USD)All components are wor...

DMA reset?
I have an A/D circular DMA that collects 192 samples...There can be times when an asynchronous push button event interrupts this while it is collecting. Can someone tell me the quickest solution for resetting the DMA so that after I service the push...
STM32 UART to RS485 Communication bit Shift Problem
Hi AllI have a problem with RS485 Communication. I am using STM32f103rbt6. Only send a struct data (13 bytes). Microcontroller send this data to ADM4855ARZ (RS485 IC). Data sends correctly ( ı checked with logic analyzer). Than this data goes RS485 t...
