Hey there,I am facing a problem with the clocks on the STM32H755ZI. When I let a timer run at 50 kHz I get only smt. like 49.92 kHz out of it with sigma = 13 Hz. So there is at any frequency a steady offset of -1.2% and a sigma deviation of 0.03%. I ...
Hello,I am using the MCU : STM32H745XIH6 in my currnet product from last couple of the years and it is working fine till.Recently, we face the issue in I2C line.I2C3 line connected with,Super capacitor Board through connector(there is I2C IO expander...
Erratum 2.2.1 (Unstable LSI when it clocks RTC or CSS on LSE) indicates the following workaround:If LSI clocks the RTC or when the LSECSSON bit is set, reset the backup domain upon each VDD power up(when the BORRSTF flag is set). If VBAT is separate ...
Hello Team, I need to connect an external NAND flash with STM32H753ZIT6 controller. What is the maximum capacity of NAND flash that can be interfaced with the FMC controller on the STM32H753ZIT6? Thanks in advance
Hello,I have a relatively simple program where I am trying to go into stop 0 mode while my ADF uses GPDMA to fill a circular buffer with callbacks triggered at half and full (i.e., double buffering). The goal is to go to stop 0 mode between callbacks...
I am attempting to use TIM1 CH1 to produce a 4MHz PWM with 50% duty cycle, to be used as a clock input to a knock sensor. TIM1 is on the APB2 Timer Clock with I have configured at 200 MHz: To get a 4MHz frequency I have PSC = 0 and the ARR/Counter p...
hi all,I'm Trying to send a string from STM32F401RE MCU to EPS32 Via UART i have programmed both STM as well as ESP32 and i successfully verified that data is available on UART pin of STM Data on UART Pins of STMBut I'm not able to receive data on E...
HII need a simple timer that can make a PWM signal BUT with custom pauses or a relax period every number of pulses ... I have the code working very well with no relax , but I do not know how to write the relax period in the timer script itself...Here...
I want to use two internal comparators to monitor current in a circuit. When the current gets above a level I want to turn off my switch, when the current falls below a level I want to turn on the switch. This needs to be done at a speed that is to...
Hi,1, Im searching for an mcu which can handle a HS/FS communication(sends data to PC 50*8830bytes) with a PC, and an USB fs communication with a external 4 port hub. the hub will connect 4 stm's which sends data(1316 bytes) periodicaly and sincroniz...
