We are developing using STM32H743.We want to set 100MHz for SPI1 CLK and 117kHz for SPI2,3. However, we cannot set it because of "clock tree" and "maximum divisible limit is 256".Is there any way to achieve the above configuration?
About SCLK frequency for SPI communicationWe are trying to set 40MHz for SCLK.What is the maximum SCLK frequency we can set?Is there an upper limit depending on the microcontroller?
Hello experts in my solar inverter i am running pwm at 19k with break enable function polarity high ,i have pulled down breakinput pin with 1k and has not used additional circuit of lm393 yet to control break but the break function falsely trigger au...
Hello everyone,In my project, I am using the STM32L486VGT6 microcontroller to manage several hardware peripherals. Additionally, I plan to utilize the bootloader feature to flash the code via the USBFS interface.As we know, when the MCU enters bootlo...
Hello,I am newbie and i have project with STM32F407G-DISC1 and PMOD I2S2. It generates two RNG values at start and with buttons switches digital filter correspoding to RNG value and shows it on LED in binary. Digital filter length and coefficients ar...
Hello,I used CubeMX for a design for H75x in LQFP176.I was able to configure SDCKE0+SDNE0 signals of SDRAM Bank 1 to PC2_C and PC3_C.Now I wanted to configure a SDRAM test using JTAG boundary scan but the JTAG tool manufacturer claims that these PCx_...
I’m attempting to configure TIM3 to count up on pulses received from an external trigger on TIM3CH1 but I'm not seeing CNT change.I’ve followed the sample instructions in the datasheet (RM3099 Rev 3) (for External clock source mode 2--all registers m...
Hello.I am trying to migrate from stm32f407vgt6 to stm32h742vgt6, is there any difference in spi specifications?Please give me your best regards.
Good day, everyone.I'm trying to launch SPI1 under Arduino IDE. The transmission didn't work and I switched to direct control of the registers. The code used is below: #include <Arduino.h> #include <SPI.h> void setup() { SPI.begin(); Serial1.beg...
Hello All,I am new to STM32 controllers and am working on flashing my application binary using Xmodem (bootloader) on the STM32U5A5VJ controller. The controller has secure and non-secure memory regions: Secure region: 0x0C000000 to 0x0C3FFFFF Non...
