Hi, its my first post Let me introduce myself, my name is Manuel, I am from Spain (English is not my native language) and I have joined the forum looking for help. My profile is that of a maker with very little programming experience (an AI maker). A...
Hi, I want to go to sleep/stop mode with STM32 and wake on interrupt. After last interrupt it should wait for 10sec and go back to sleep. But I see an edge case where interrupt could occur just before going to sleep/stop mode.How do I handle interrup...
Hi,i have new design that i am migrating to the STM32G071 and having issues with the SPI1 port PB3,PB4,PB5. Changing CPOL and or CPHA during init code do not seem to have any impact, when powered down and restarted.I am seeing 9 clock pulses when se...
I have a PCBA design that uses a Molex Picoblade connector instead of RJ45 due to enclosure height restrictions. The PHY IC is a LAN8742A and the MCU is STM32H743VIT6, the ethernet is also POE.I have spliced, a ethernet and 8pin Picoblade connecto...
I have an STM32L011F4P6 with an RTC. It is running at 3.3V and 16 MHz off the internal HSI RC clock. The RTC is driven by a +/-20ppm 32.768 KHz crystal. It is running at room temperature (23-25C). After calibration, I am losing several seconds pe...
In my project I've set the SPI clock to 125MHz; with a SPI prescaler value=4 all works good, when I set it to 2 the SPI stops working and ther is no clock signal.Any helps ? Thank youCarloV
If I am correct, the descriptions of - HRTIM_ADC2R - Bit 22 - HRTIM_ADC3R - Bit 19 - Bit 13 - HRTIM_ADC3R - Bit 22 - Bit 13 - Bit 10 - Bit 5 - Bit 4 - Bit 0are not correct in the RM.They all describe trigger event generation but th...
Hey guys, I'm looking for some suitable HexaSPI PSRAM and also the OctoSPI Flash for the STM32N645 board I am just building.. I cant find the parts used on the DK so do you have a list of supported memories? I need 256Mb PSRAM and will start with a 1...
Hello,I dug deeper into PSSI behavior, and and I observed unwanted behavior. From my point of view it is a bug.PSSI is configured as:OUTEN = 1 (transmit mode)CKPOL = 0 (outputs driven on rising edge, inputs sampled on falling edge)RDYPOL = 0 (0 at in...
Can i use UART + DMA ( normal ) + RTO ? I try to add RTO but when activate RTOE bit the DMA buffer stops fills .I take interrupt with active RTOF , stop DMA , but nothing in buffer !? I use stm32H7 with hardware implemented RTO. Can some one to give...
