Hello,We have interfaced a NOR flash (S26KL512SDABHN020) with STM32L562 over OctoSPI in Hyperbus mode. The Low level drivers were found from one of the forums of ST community and were ported in our code. We are unable to read/write data at the base a...
Drivinng ann H bridge to generate a sinewave , PWM generated and driving the H bridge .The PWM siganl as followsThe H bridge Connection as shown below.While appling supply the Low side MOSFET Q2 is Heating up Why so ?I added some dead time also nothi...
Hi as i want to use hall sensor interface to my input pwm capture We can see these timers associated with digital hall,Which one i can choose TIM1/8/20 or TIM2/3/4/5 also suggest on 16 bit and 32 bit timer preference. Also can it be preferable to u...
Dear sir/Madam,I have made a custom stm32f303zet6 board for my applications. I started with a basic Led blink program. program is flashing into the MCU but the led blink is not happening. Here i am attaching the schematic for the custom board. Please...
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...
