I'm doing motor drive project and its six pwm signals output from F429 connect with drive IC-- DRV8302 directly, but pwm rises and drops lowly (above 10us) as attached picture. I think this rising time takes too long,is right?Thank you.
Hi, In STM32746 discovery, We are using external flash memory in memory-mapped. My doubt is that all external flash memory supports memory-mapped mode or few specific? Can I use MX35LF1GE4AB in memory map mode?
Hi, I have been conducting some memory benchmarks to try and reason about how long it takes to program the flash during runtime. The procedure is to erase the page in the flash, then write to it using the flashProgram and flashErase functions provide...
Trying to build my own raspberryPi wireless SWD debugger.(bitbanging SWD, without stlink)I am able to flash and halt the code trough cubeIDE but openOCD is not able to reset the chip, i have to do it manually for now (see gif above).Pesky errors im g...
Hello,with the same procedure that reads the DP TARGETID fine on STM32F7 and STM32H7, on STM32L5 the TARGETID only reads 00000001 (RM0438, p 2000, DP target identification register (DP_TARGETIDR).Do I do something wrong or is this an errata not yet l...
When STM32F439 power supply is dropping from 3.3V to 0V what will be state of GPIO which is configured as Mode output pp, pull up and speed_fast whether it will hold to value mentioned in GPIOx_ODR
If we initialize the GPIO pin as Mode output pp, pull up and speed_fast using HAL_GPIO_Init() API then what will be the state of the GPIO pin when pin status is not set using HAL_GPIO_WritePin()
I am trying to flash code in my stm32 via SWD interface with a raspberryPi.(swd is bitbanged no stlink used)With my raspberryPi Zero i followed this tutorial, wired the raspy with my stm32f105 together.My openocd.cfg file looks like:source [find inte...
Hi, I have issues while using "FATFS R0.12c" over SDIO on my STM32F407. I do SDIO write to file on main loop, but I also have "TIM2/TIM3/CAN1 RX0/CAN1 RX1" interrupts which has other logic (for example TIM2 sends UART message every 100ms to update th...
When both UARTS are transmitting & receiving, my ADC conversions (via DMA) sometimes do not complete. If I double clock speed (which I do not want to do in the product), the problem goes away. I cannot see any issues in my code that would cause this....
