I have a design where I am using both I2C1 (external ADC) and I2C2 (external EEPROM). I have no problem making I2C2 work perfectly. The MCU both transmits and receives messages with no problem and I can see in on the Oscilloscope. However, when I att...
We have the following situation: We want to use the FDCAN of the STM32H743ZI with 500 kbit/s. We've got followingconfiguration parameters for the FDCAN1:hfdcan1.Instance = FDCAN1; hfdcan1.Init.FrameFormat = FDCAN_FRAME_CLASSIC; hfdcan1.Init.Mod...
I want to use coocox os with an stm32l083cz . while i am compiling the code the following error appears. /tmp/ccpwcyyg.s: Assembler messages:/tmp/ccpwcyyg.s:242: Error: selected processor does not support `stmdb R0!,{R4-R11}' in Thumb mode/tmp/ccpwc...
Hi all,To be hontest, I am a beginner when it comes to timer and capture hardware. Maybe someone can help me figuring out what the best way is how I can measure the time between two separate impules i get on two separate lines. Accuracy shall be very...
Implementation on: STM32L476RCI can configure a periodic sleep cycle by waking up through the RTC through calling HAL_RTCEx_SetWakeUpTimer_IT.I'm now trying to handle an EXT interrupt while in this periodic sleep cycle.The goal is to handle the EXT i...
rtc year is uint8_t, does anybody know how to identify year less than 2000 or more than 2000?Regards,
Hello. I try to calculate some pulses by wakeups from shutdown mode. I have 2 pins which areWKUP1, WKUP4. They are configured to wake up by rising edge. But sometimes when only 1 of them is rising, I receive 2 notifications, from both pins.The proble...
I'm working on a project for a battery charger and for safety purposes I want the complementary outputs of the HRTIM to be disabled when the core is halted. On the STM32F334, setting the HRTIM_STOP bit in the DBGMCU register resulted in both the HRTI...
Hello, We have been trying to read 12 bytes of data on EC25 from stm32 controller.On the first run, data is transmitted by stm32 in slave trasmit mode and EC25 is reading the data correctly. We are able to capture the read log on EC25[Master read mod...
I use 2 board for generate pulse and count pulse.I generate pulses with 4Hz frequency by first board and print number of each pulse also when I press button pulse production stops and then after 20ms products a another pulse(I things micro in second ...
