I've got a strange situation with a custom board with two STM32F4 chips. My master STM32F4 transmits data over SPI in blocking mode every few 100ms. At the moment the data size is 12 bytes but in theory it should be any size. The Slave chip is in SPI...
From the datasheet PA0 is listed as a 5V tolerant IO (FT type). Does this maximum of 5V still hold if the pin is mapped to the ADC input? If not, what is the maximum reading for this case?
How to give the STM32L4 series LPTIM1 timer an initial value,It seems the register address is closed to the public
STM32F767 SAI SPDIF Output, NODIV and Clock GeneratorWhen NODIV bit is set in SAIx->CR1, the SPDIF output frequency is as it should be.Example:clock in is 25.6 MHz, sampling rate is 200 kHz, factor is 128, as it should with "symbol rate" (2 channels ...
Hi,I am using the serial wire debug SWDIO and SWCLK on PA13 and PA14 to program an stm32g031. Can I use these pin after the debug? If yes, do I have to modify some dedicated register (in addition to the GPIO registers) to use thiese pins as GPIO?
Hi,I´m trying to transmit (send only) 3 bytes with the SPI using interrupts, and deassert the chip select line from an interrupt routine that should be triggered when the transmission ends.The line 11 (// more stuff here ...), doesn't run immediately...
Heyho,after having found the PHY problem I can stream some audio via TCP.But when I don't get the data out fast enough (e.g. TCP ACK takes too long so that there would be a buffer overflow), I stop the transfer and send some UART messages.Without hav...
I'm trying to blink variation of morze code with specific string on yellow led, but the led just turns on and stays on for a little bit and then turns off.When I try to debug it step by step it works as it should, but the moment I press run, it does ...
Hello,I want to read 8 bit ADC value from ADC2(PA1 pin) and use it to control a LED which is connected to DAC1(PA4 pin). I wrote a code(using registers) as below, however, I cannot read the ADC value(I tested it on STM Studio). Where is my problem? T...
Hello,We need to track milliseconds of Edge Change time of External Interrupt. So, How Can this be done?Thank You
