Hello everyone, I have a board.STM32F429I DISCO1, I want to read, say, two bytes of parallel data from port A{15:0}, into the DMA buffer, every time a rising edge of some signal comes to the microcontroller from the outside.How exactly can this be im...

hello everyone, I have a board.STM32F429I DISCO1, the question arose:is it possible to read the parallel , a 16-bit from port(from the input pins) using some external interrupt (for example, using the rising edge of an external-nterrupt), to the DM...

Hello everyone, I'm asking for your advice. I use STM32F429I-DISCO1 board, I want to use I2S_3(PCM3) in SLAVE mode .The <WS> signal is located in PORTA 15 pin, at the same time the same pin is connected to U4 (STMPE811QTR) as <TP_INT1> signal (output...

Hello everyone, I'm asking for your advice. I use STM32F429I-DISCO1 board, I want to use I2S so that the reception and transmission occurred simultaneously, on different lines and only one frame on each <WS> signal, and I think in order to quickly i...

Hello everyone, I need help .I noticed a very interesting problem, which is this.I use STM32F429I-DISCO1 when I activated I2S_2 in the master mode PORTB_13 pin = CLK , but in reality it was always = HIGH level , after that I deactivated I2S_2 and con...

If instead of STM32F429 I take STM32H730, can this microcontroller solve this problem (Configure DMA to transfer data from the GPIO port for example A{15:0} to a memory buffer)? , and how many clock cycles will it take for the data from the pin to be...

Can I in board.STM32F429I DISCO1 , Configure DMA to transfer data from the GPIO port to a memory buffer ?because I dont see that , in CubeMX may support direct GPIO to memory transfer for this use case ?but can I manually handle this , ? for exampl...

thanks for the response.I want to read, say, two bytes of parallel data from port A{15:0}, into the DMA buffer, every time a rising edge of some signal comes to the microcontroller from the outside.How exactly can this be implemented ?

Yes, I made these settings, it’s just that my system is like this, sim7600 and NAU8810 codec are connected toeach other, I want to cut off the lines to fit with stm32 between them, make my own digital additional filtering,for this I must connect one ...

Your help was really very valuable, and I tried both PCM-s (I2S2 and I2S3) on the STM32F429I-DISCO1 boardin practice, a lot became clear in practice. But there are hardware nuances that are not fully understood.At first, PORTB PIN_13 (clk) did not wo...
