I am attempting to drive some I2C 5.0v / 3.3v peripherals via the Sparkfun Arduino Qwiic Shield connected to an STM32H7451-DISCO.I can't seem to raise the devices on the I2C bus despite being able to communicate with the audio codec and LCD which are...
Hello, I was wondering if the FW compiled for STM32L476RC could be safety flashed in STM32L476RE which is the same core but with a larger size of flash.
I am using the DMA to collect the ADC data's. The ADC data's are now configured in a single mode and ADC is triggered at the rising edge of a pulse (I am using TIM8 for the pulse generation and the pulse can be set for 10us till 400us, i am also usin...
Hello geeks...Hope all are doing well Recently, I'm dealing with the STM32WB Tickless Idle mode of the FreeRTOS (CMSIS-V2)I'm intended to achieve the lowest power consumption with STOP1/2 mode To do so, I'm following the official tutorial for the sa...
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?
