ES0320 [1] describes an I2C errata "Spurious bus error detection in master mode":DescriptionIn master mode, a bus error can be detected spuriously, with the consequence of setting the BERR flag of the I2C_SR register and generating bus error interrup...
Hello,I have created with stm32cubeMX full configuration for my project.I have 3 memories:nor flashSRAMFPGAI also find the following information in my cubemx project:Chip Select:NE1 Memory type:NOR Flash Address:24 bits Data:16 bits Wait:Asyn...
I realize that I can read the ID Code Register at 0xE0042000, but I am not sure how the silicon revision is indicated for a specific device. Is it readable though the codes on the device itself?
I am trying the DAC in the STM32F4, so far I am using just the HAL_set_value function and I am trying to get a clear output voltage. I am using the STM32F46 nucleo board.I see that the ripple at the output (using the internal amplifier) is far highte...
I want to use RTC of stm32l031k6. But once I tested it I noticed that it counts 8 seconds more in a minute. I need a precise rtc. Do you have any advise what should I do.Thanks,
According to the STM32F4/F7 data sheet FMC controller support 32-bit bus PSRAM. For my application I would like to use this configuration, due to a high bandwidth requirement. However, in the market it seems very difficult to find a PSRAM with 32-bit...
I'm trying to change GPIO mode at runtime, i could able to change mode from input to output and vice versa. But once configuring GPIO as EXTI i'm not able to change it to any other mode. and even if i try to change, ISR is getting executed.
On last version normal rtc init code was so:/* RTC init function */ static void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime; RTC_DateTypeDef sDate; RTC_AlarmTypeDef sAlarm;...
