hello! i am using stm32f429 mcu ,i want to add a sdram as the main RAM.My sdram detail informatin,512K Words x 16 Bits x 2 Banks.i donn't know how to connect the pin which connect to sdram and control the internal bank of sdram to the sdram.s...
Here is the situation, there are 2 developers. Both developers download the code from the repository and issue a build & debug cycle.Test_functions is an array of function pointers. In the debug session, Test_functions has different values (given in ...
Hello,I'm having a hard time debugging a hard fault I'm experiencing.The hard fault occurs in the handler of external interrupt. Here's it's code:extern "C" { void EXTI2_IRQHandler(void) { static uint32_t last_sample_time = 0; if (EXTI_GetITS...
How can i transmit data through usb fs without ftdi usb to uart converter?
Posted on July 04, 2018 at 22:56I am doing now small project with STM32F0. I would like to generate two PWM signals simultaneously using DMA. Everything is working fine if I am starting one of two PWM Generators. When I start two works only first on...
Hello everybody, Here is my needI am using STM32F469NI, and I need to generate a PWM signal using timer1. I need to generate a burst of 4 pwm cycles. Each cycle must have a specific duty cycle value. I already did that using DMA that load each duty c...
Hello,"The dual-bank memory organization is different from the single-bank: the single-bankmemory contains 256 pages of 8 Kbytes" should read "128 pages of 8 Kbytes"Bye
I have Timer configured in Input Capture Mode and DMA2 Channel 6 Stream 1 configured to transfer data from GPIOC to frame_buffer. It works, but only once - after first use there was data and in next transfers there where only zeros. To have it workin...
We are suing STM32F429IET6 in our project. The schematics as follow:if VBAT=2.2~3.6V :backhand_index_pointing_right: :backhand_index_pointing_right: :backhand_index_pointing_right: Power off the VDD and wait 0~180 seconds, then power on again. The R...
