Hi,I use RTC for timing FreeRTOS (also in Tickless mode - in STOP mode) I use ALARM A in rtc. I noticed one weird behavior. Some times for examaple after 5 hours of running program the ALARM A is missed - no Interrupt of alarm happended, althougt the...
I am trying to use ov5640 camera with stm32l4r5 board nucleo-144. The ov5640 has SCCB bus which is similar to i2c. But ov5640 has register with 16bit address (0x300A, 0x300B like this). I used CUBEMX to initialise i2c pins and generated code. How can...
I am using STM32F407VG board. I wanted to know about the reference voltage and ADC resolution available on this board. I couldn't find the exact info related to these parameters in the datasheets.
Hello AllI understand that debug steps advance instruction by instruction (whether in C or assembly). I wonder if there is any way to advance CPU clock by CPU clock. I need this to debug an issue I have with the SysTick timer.Thanks
Posted on June 26, 2017 at 09:23Hello. I have custom serial bootloader, which located in the beginning of user flash (sector0), and also user application, which burned by bootloader starting from sector 1 (slightly modified IAP example from ST). Whi...
If loading the on-chip flash from a .hex file, the Write Memory command can be used to write the hex file data records. However, what should done with the start address? Where does that get written? (Assumming an STM32G0, in my case.)
STM32L041F6 - I configured RTC for wakeup every second from Stop mode. It works ok, but after external reset (NRST pin) it not working. Program run in main while() only once, to line:HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);...
The STM32L4xx have excellent 4.5~5MSa/s simultaneous sampling ADC but abysmal 80 MHz CPU clocks. The fast STM32F's have faster clocks but ADC are <2.5Msps. Is there no MCU with 5Msps ADC and 200MHz+ CPU clock?
I am using STM32L432KC: USART1_TX+USART1_DE+USART2_RX. Both are LL drivers.Currently I have to:- created 2 additional MX projects- one with USART1_TX+USART1_DE and dummy USART1_RX pin, set to Mode: Asynchronous + but Data Direction: Transmit Only + H...
