Reference manual RM0383, "STM32F411xC/E advanced ARM®-based 32-bit MCUs", says:18.6.7 I2C Status register 2 (I2C_SR2) Note: Reading I2C_SR2 after reading I2C_SR1 clears the ADDR flag, even if the ADDR flag wasset after reading I2C_SR1. Consequently, ...
Hi. I've been trying to work this out for a couple of weeks now and am pretty well stumped. I can't even get VBUS power working, so suffice it to say I'm not getting very far. All the examples seem to be for Nucleo boards, so not sure if it's even po...
When checked on telnet that there was no response from the ST web page, when requested for headerIs there any issue in using ST website for getting the real time?
I want to switch from FreeRTOS to Azure RTOS ThreadX. In FreeRTOS there is the function xQueueSendToBackFromISR() - It is used to write data to the queue from an interrupt service routine. FreeRTOS interrupt provides an interrupt safe version of queu...
So, I suspect I've configured something rather obvious wrong, but I'm not sure what.We've got a product with a OTG USB port we'd like to run in device mode. I'm trying to configure it using the USBD high-level drivers provided (thanks!).I'm finding t...
On a L412KB core HAL is quite unstable if the core receives ~250K interrupts per second. Without HAL I could get everything stable, but for read-ability I would like to put the interrupt service routine in another file as STM32xxx_it.c Besides that, ...
stm32h7xx_ll_utils.c throws a warning "no LL_RCC_CalcPLLClockFreq" function at line 930. The function exists in stm32h7xx_ll_rcc.c but has a conditional compile USE_FULL_LL_Driver.Calls to conditional compiles should be under the same conditional con...
Using HAL library set up RTC, but at times SKIPS seconds. WHY?This is the setup:static void MX_RTC_Init(void){ /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime = {0}; RTC_DateTypeDef sDate = {0}; /* USER CODE BEGI...
Hello,I worked until now with FreeRTOS. And in FreeRTOS there are Trace Hook Macros.Is there an equivalent on Azure RTOS ThreadX?Trace hook macros on FreeRTOS are a very powerful feature that permit you to collect data on how your embedded applicatio...
