I am working with STM32F411/13 controllers from ST. And i observe an issue with SPI reads if i-cache is enabled. More details as below:I do have the FLASH PRE-FETCH enable set. And Flash wait states properly configured based on the System clock.And a...
I am trying to protect code(in flash) and data(sram) using fire wall feature But board is resetting when exucute the function. Following is the code to initiate and enable fire wall. void firewall_init(void){ FIREWALL_InitTypeDef firewall1; firewall1...
Hi,As far as I remember, I've read something about that a while back. I was wondering if I can send data to a memory-mapped device (FSMC/FMC) in a continuous loop a byte per iteration using the DMA peripheral. Thanks
Posted on October 28, 2016 at 02:11We use PWR_EnterSTANDBYMode library function to enter the standby mode. I have added line to enable WKUP pin. The STM32 enters standby mode most of times. But, sometimes(once in 25 or so times), it just reaches the...
I want to generate 1 Mhz with one timer but I want to stop it for 1 ms and then generate for 5 ms.I see that there is instruction HAL_TIM_Base_Start_IT looks like I can start and stop one timer with anther, I am using Cube MX and keil.
I am going through an existing implementation, where my MCU's(STM32L486) SPI1 (PA4(NSS), PA5(SCK), PA6(MISO), PA7(MOSI) is used as master, the slave device is a zigbee stack.Currently the master's SSL is configured as Software managed, (SSM=1, SSI= ...
Hellousing HAL libraries is it possible to disable for a short time an external interrupt pin ??I have had a look in the HAL GPIO files and can not see anything usefulJust want to disable while a trigger a debounce timer, there must be a way of just ...
Hi ,I ma looking at using the internal flash for EEPROM emulation, using Atolic and STM32F302ccI have read the aplication note on eeprom emulation and quite a few stackoverflow discussion as well as a few ST community posts which seems to focus arou...
Here I am trying to generate a simple example of sine wave to pass over I2S and just send the data on ZL38063(slave) using STM32F446ZE . Clock is working fine @1.5Mhz and WS @48Khz and also getting PWM data on SD line. I am not able to hear any kind ...
