Hello!Configured 3 input channels to be checked by two ADCs in fast mode. First ADC request works perfectly, but all next request ADC2 data is not synchronized with ADC1. It seems, ADC2 stops incorrectly and continues to change the channels.Here is a...
I am trying to code SPI functionality to connect with an external 16-bit ADC. The STM32 only receives data from the ADC, so only a MISO and SCLK line, along with a Conversion/CS line is required. I am currently using the 32F072BDISCOVERY board to te...
Hi, team, I am work on stm32g030f6's uart dma. And config them as idle interrut mode to receive data.When the uart data on high frequence like 10bytes/30ms , the CNDTR will be aways MY_BUFF_LEN -1 , so i only can receive 1 byte data. After reset the ...
Hi All,I am using STM32F74xxx.I need to count micro seconds. currently we are using HAL_GetTick(), function but it gives the time in ms.After I searched on google I found some ways to get micro seconds count, and I tried it but no luck.can any one he...
I work with STM32H753 through 3-rd side hardware (Algocraft WN-1 programmer) and have an access to the registers. I try to read/write GPIOJ pins. For this purpose I enabled GPIOJ clock by writing the AHB4 peripheral clock enable register (RCC_AHB4ENR...
Dear Community Members & STM32 fans,Peculiar year it has been, 2020 comes to its end. This is an opportunity to say "Thank you" because:you don't hesitate to bring help to othersyou help us improve our STM32 offeryou have confidence on ST Communityyo...
it seems that a write to AXI SRAM very shortly before a system reset (via AIRCR) gets lost. I wrote a very short block of code that simply reads a word from 0x24000000, increments it, writes it back, and resets the processor. I can see that the value...
I am using STM32H743BI controller. I need to use backup RAM as nonvolatile ram. So I use external 3V battery and LSE 32.768 crystal for RTC. RTC works well but I can not use backup RAM. I use code like below;PWR->CR1 |= PWR_CR1_DBP;while(((PWR->CR1 &...
Is there any part from STM which able to operates as bluetooth HID keyboard as well as bluetooth touchpad?
Hi :) So I keep reading everywhere that leaving a CMOS input pin floating is bad because it is high impedance, can oscillate, etc. I understand and agree.But while a MCU is starting up (or when you're programming it) all its pin are in input state un...
