Setup:Using a STM32U575, connected on OCTO-SPI1 to PSRAM (IS66WVH8M8) 8MB in size. The STM is configured in memory mapped mode, hyperbus enabled, no DMA or Cache enabled, & wrap/burst mode disabled. While testing the PSRAM using Barr tests, found tha...
I'm have the HAL_I2CEx_ConfigDigitalFilter call in my H743VIT6 code with the setting of zero.The AI recomends 4 to take out 8ns noise pulses, RF; etc., but where is the STM documentation or an AN about this, and the analogue filter?Its not in the RM0...
I'm using stm32u535RCT mcu and I've requirement of zero crossing detection using analog watchdog.I need 6 channels and configured DMA circular buffer to collect 1Kb data on each channel. Channel 5 is mapped to analog watchdog.Here I want to understan...
We have a STM32H725 and would like to use the RTC timestamp when entering/exiting standby but from what I understand from the reference manual this is not possible? I did run a quick test and the event doesn't seem to fire even though it works as exp...
HelloI trying to figure out what the maximum frequency is for the TRACECLK stm32u5A9.I found this post for the stm32h5https://community.st.com/t5/stm32-mcus-products/traceclk-freq-in-stm32h5/td-p/604127does the same apply for stm32u5 were can i in t...
Where using a STM32G081EBY6TR25-pin wlcsp - package This part doesn't seem to have pins for a external clock pins. Just making sure that the internal clock is sufficient to handle USB-PD. It say's that 6 to 18mhz is fine, but really its looking fo...
Good morning,I'm developing a device with these requirements: STM32F446RET6No internet (NTP) or GPS connectionReal-Time clock, set manually (so, the less often a user has to set it, the better)Outdoor -20°C~70°C temperature range (most installations ...
HI,I have been evaluating the DAC module of STM32H743IIT6 recently. However, the data provided in the data sheet does not specify the temperature conditions under which it was measured. When I conducted the high-temperature test at 125℃, the measured...
Hi, Currently I working with Nucleo-H7S3L8 board and trying get XSPI interface up by trying to read memory device ID in STR OPI mode. It is not working yet.Can someone share detailed steps to get it to working stage? I am able to read id in single SP...
We're bringing up yet another custom board with the STM32H735 as the core processor. Built the first one, handed it to the software guy, and a few minutes later he says it's broken. Won't program, won't go to DFU mode, nothing. "You must have zapped ...
