Resolved! Is it possible to use Octo-spi as a regular SPI?

Hello, at this moment i'm investigating the possibilities of our current system and would like to know if the 2 Octo-spi peripherals can be used as legacy, normal SPI.

Resolved! wake up with rtc from standby mode does not work anymore after having gone in uder drive stop mode

The code works if i enter in stop mode but not if i enter in under drive mode.I think i have to reinit something after stop mode but i dont find what.Here is the code :int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_ADC1...

No Space in execution region with .ANY

Hi,I am working for an project with STM32L496 target board. When i tried building the project, i got the error saying,ERROR: L6406E : No Space in execution region with .ANY main.o(.bss).I am trying to use full SRAM memory present(320KB) for the globa...

2 x PWM with DMA

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...

Dual synchronous DMA stream for timer 1 PWM preriod and duty cycle management?

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...

RM432 Rev4: Typo in 3.3.1 Flash memory organization/Dual-bank organization on 1 Mbyte devices

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

DMA running only once

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...
