Hello. For a project, I need to read 4 channels analog data and save them in to the sd card for 10 seconds. I should record every data minimum with 750 Hz. And then I generate pwm signal with these data. I tried that but it was not successful, recor...
HiI want to use spi6 on stm32h7 controller in DMA mode, i see i can use BDMA instead of DMA. looking at the reference manual, i see following about BDMA"The BDMA is used to perform programmable data transfers between memory-mapped peripherals and/or ...
Using the STM32L452. According to PM0214 Rev 10 page 40 there are 256 exceptions utilizing memory 0x0000 to 0x0400. According to RM0394 Rev 4 page 324 Table 46 only identifies 84 interrupts utilizing memory up to 0x0190. In order to be safe shouldn't...
Hi,I'm trying to see what the maximal frequency I can achieve using the STM32F407-discovery board.So far I have found the following:using TIM1 Internal clock (168MHz)Output pin PE9If i put the period at 1000, I get the following result:However if I p...
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
