Hi,I've been working on programming my STM32F745 for some months now, step by step playing with the different peripherals. So far so good. I've been also doing step-by-step debugging with OpenOcd and STLink V2.Today things started to look a bit weird...
I'm using the STM32L4 Nucleo board with a N25Q256 SPI Flash attached. I can successfully read and write from the spiflash using the QSPI peripheral + HAL layer in standard SPI mode. However when switching to Quad mode, every so often during a longer ...
On a my Nucleo-L476RG board, I used cube to only activate an LED connected gpio (PA5) - Nothing else.Then I programmed some blinky code into the main while loop: HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, RESET); HAL_Delay(1000); ...
my implementation purpose is,i have a battery charger module having i2c as communication type and a fuel gauge module having SMBus as communication type. so i need to simultaneously communicate with both the module. so my question is how can i use th...
On page 22 of this datasheet:https://www.st.com/resource/en/datasheet/stm32h753xi.pdf"Figure 1. STM32H753xI block diagram" shows 200MHz and 400MHz.Shouldn't this be 240MHz and 480MHz instead?The document states "Updated Figure 1: STM32H753xI block di...
Hello,I have an app working fine with a device that works at 1200bps 7N2 using a Clock Tree with HSE CLK configuration at 8MHz.If I change the Clock Tree to work with PLL to other frecuencys like 16,32,64,72 every work fine, even if I config at rare ...
Hi, I am using STM32F103VG micro-controller. I am trying to program the memory in range 0x8014000 to 0x8090000. My code is able to program the memory till 0x807FFFF but after that it failed to write into memory i.e. problem happens after I start writ...
my problem is that the DMA only writes to the first address of the buffer, means that when i look on the buffer, the last byte of the message is stored in the first place of the array, and the rest of the data is overwritten.what could be the problem...
eternal interrupt routine works with some delay if i remove delay then it not work what is the reason how can i solve this?*code work with some for loop delay.void EXTI3_IRQHandler(void) { /* USER CODE BEGIN EXTI3_IRQn 0 */ for (int z = 0; z < 50...
