Need to generate a repeating waveform with external SPI 16-bit DAC.Using a table of values in memory, repeatedly loop through table outputting values to DAC.Delay between outputs is constant. No glitches at repeat!DMA only (no interrupts).What's the ...
< What I want to do? >Send string messages(AT command) from STM32 microcontroller to LTE module through UART, receive the reply, and store the received data in a string variable. I tried HAL_UART_Receive function and it works. However, it doesn't com...
I am using the STM32F4 Board and Wolfson pi audio card for my problem, which I stated down. I am trying to pass my own sample values to the DAC, then passing out them through the speaker. Then I want to capture/sense those values (emitted signals fro...
Hi,I'd like to use USART for multiprocessor communication. For this I have to configure the TX pin to an open drain mode. But this option is not available: MCU: STM32F446ZEH6STM32CubeMX: 5.1.0Best regards,Eugene
i have light detection sensor circuit , it will give 1v output and 10 microsecond time period signal.this sensor gives voltage and time period varying depends on light intensity.i wan to measure the amplitude and time period of the output signal usi...
Hello,There seems to be some limitation about PSRAM controller and MDMA:Although that are several channels that can be used with MDMA, there is only a single interrupt for MDMA.If I understand correctly, it means that mdma can't be used with several ...
Posted on September 25, 2017 at 15:23Hey guys,for speed optimization I want to use ethernet interrupt when a new packet recieves. For this, first I changed heth.Init.RxMode to ETH_RXINTERRUPT_MODE and after that I added the interrupt handler with:vo...
STM32F302RBT...I want to use OpAmp1 in PGA Connected mode feeding ADC1 IN3. According to CubeMX the OpAmp pins VINP, OPAMP_VOUT and VINM are all 'Used' even though VOUT is internally connected to the ADC and VINM is not being used.If in the cube I ch...
Dear All,I have some problem with the STOP mode 2, doesn't work! In my program I use the following periphals:I2CSAILPUARTUART2My microcalculator is the STM32L4R5ZIT, and I use the nucleo EVAL board.To go in the STOP mode 2 I use the following command...
