Regarding function calls when performing SPI communication in half-duplex mode.We would like to develop a product that performs SPI communication in half-duplex mode.Are there any sample programs in which the slave side transmits and the master side ...
I know that the question will be trivial, however, I do not understand why the instruction uint8_t dataRx[4] = { 1 }; does not initialize all the elements of an array to 0 ... but only the first one:I have programmed little in the last while so I wil...
We are trying to develop a device that uses SPI communication (Receive Only Master).Are there any sample programs for SPI communication (Receive Only Master)?Which should be executed first: "Receive Only Master HAL_SPI_Receive" or "Transmit Only Slav...
I have some questions. I read that STOP mode has a "RAM retention", so when it wakes up it the whole data is still intact (not cleared).When the RAM retention is off then the data is gone when it goes to STOP mode. So when it Wakes up does it restart...
Dear,Used MCU: STM32H7B0, 100 pins.In the datasheets we had found that TIM3 use the APB1 peripheral clock.In our case is this 120MHz. But when we use the function "HAL_RCC_GetPCLK1Freq()" we become 60MHz.This isn't correct. So what function should we...
Dear,Using STM32H0B0, 100 pins version.we wish to sample 1 input with ADC2 at a fixed frequency. This must not deviate and for this we use timer 3 set to the desired sample rate.In the pictures we use 100Khz, but later to go to 1Msps.So the timer 3 i...
Hello everyone.I am working on a project and I have two stm32 MCU connected over SPI interface. One acting as a master (STM32H743VIT6) and the second acting as a slave (STM32C011U6) in full duplex.When sending data between the two devices the receive...
Hi,I am confused with pin toggle timings, why I am getting non equal pulse widths like in the picture, I turn off all compiler optimizations and disable all of the interrupts, code is simple pin toggling. My controller is STM32L431 running on 80MHz.T...
This is on STM32F103C8 (bluepill)The A0 is connected to a voltage divider between bluepill's 3v3 and GND,And the output is very noisy. adding a delay did't do not much good```void setup(){Serial.begin(9600);// Enable ADC1 and configure itRCC->APB2ENR...
I am Juan de Jesus, I am a graduate student in engineering. I just bought a NUCLEO STM32H755 board.I am writing a simple code to test this board, an algorithm that makes LED 1 blink.The program compiles very well, and after this, I have made the conf...
