1. Array of bytes? Read and write between CPUs.2. Peripheral allocations to CPU1 or CPU2? Should allocation of peripherals handled by only one CPU? What will happen if both CPU's are asking for same peripheral. How to handle this scenario.
Am facing problem while receiving file from PC as YMODEM protocol, Am just using ymodem.c an d ymodem.h file fromIAP library i have modified the code, but am not receiving Header packet only(SOH or STX), please help as soon as possible am struck here...
Hi Guys,I am newbie to STM32 family. I am currently building an application to collect ADC sensor data and operate a motor using PWM signal. I used example code to play around with it. I initialized ADC , configured the channel, and calibrated befor...
After successful test on STM32f401RE I moved my design on STM32F071 for cost reasons.I am using UART1 and UART3 first set to 9600 and second set to 115200.But on PC I can see the data only if it is set to 4800 and 57600.At the beginning used interna...
what is the role of voltage regulator in stm32f407vgt6 and how it works..that means already VDD is supplyng 1.8V and again what is the need of suplying 1.2V and how it works i want to know exact operation of it in stm32f407vgt6
Hellow.Mr.Kang system engineer in South Korea.Looking an ADC high performance STM32.The specification is as follows:1~5Msps , 2channel, PGA (if possible)
Hello, I would like to use #define macro in my program to hold application, firmware version and firmware building time. I know i can put these definition into my program directly, and make modification before I compile my program. Could I use GNU C ...
This is the code:#include <stm32f4xx.h>void main(void){//Set up PA5(LED)RCC -> AHB1ENR |= 0x00000001; //enables clock for GPO PAGPIOA -> MODER |= 0x00000400; //PA Pin 5 as GPOGPIOA -> OTYPER |= 0x00000000; //PA Pin 5 as Push/PullGPIOA -> OSPEEDR |= 0...
I have a 10 mhz external clock. I want to generate a phased locked division down to 1hz exclusively with timers. In my current test setup I am generating the 10mhz using TIM1 from the internal clock (this is to simulate the external clock). I am putt...
Hello,I’m using the B-L475E-IOT01A with MbedOS and have the following code:hall_a3 = new AnalogIn(A3);hall_a4 = new AnalogIn(A4);hall_a5 = new AnalogIn(A5);while(true) { printf("Hall A3: %f\n", hall_a3->read()); printf("Hall A4: %f\n", hall_a4-...
