I2C pin voltage is at 3.5V
I'm using the i2c on a nucleo stm32h723 board. I'm using pins PB8 and PB9 on the board. I have the pins connected to a scope. I notice that when I have the internal pullups of the board on the voltage is at 3.5V and if I dont use the internal pullup,...
Resolved! Can set option bytes in STM32 ST-LINK Utility but not STM32CubeProgrammer, Why?
Hello,I have a new STEVAL-IDP004V2, and I recently downloaded both the ST-LINK Utility and the STM32CubeProgrammer. I'm going through AN5041 Rev 5, page 22 steps which mention the board is to be programmed with the ST-LINK Utility. I started trying ...
Resolved! Bypass Capacitors on NUCLEO-H723
I am trying to design my own board using the STM32H723ZGT and using the nucleo schematic as a guide. I believed 100nf was typical for the VDD pin bypass capacitors however there is one pin(pin 62) with a 4.7uf capacitor instead. I understand the VBAT...
IR Output Polarity
Hi, I have built an RC5 IR remote transmitter that almost works on a NUCLEO-L412RB-P, with modifications to the files found in x-cube-irremote. This unfortunately does not have an STM32L4 example.The bit I am having trouble with is the output polarit...
where should i check for proper read,write,erase function for fmc_norflash
Regarding FMC NOR Flash, I recently posted about creating my own external loader for the MT28EW01GABA 1Gb NOR Flash on an H753 custom board. Experts advised me to first create a proper BSP (Board Support Package) program to handle read, write, and er...
Resolved! Why doesn't my detached STLINK board recognize my nucleo_F722ZE board?
Hi.I did "HSE on-board oscillator from X3 crystal (not provided)" on um1974-stm32.But stlink doesn't recognize my board. Why?I used an ats49 8Mhz 18pF crystal since there is no recommended crystal. C37 and C38 have 18pF attached. HSE on-board oscill...
Problem interfacing gsm module with stm32h747 disco board
We're working a camera based person fall detection device with STM32H747 and B-CAMS-OMV camera module, we want to interface GSM module with it to make alert calls in case of fall being detected but we're facing issues with the same. We're not able to...
Resolved! STM32F469-DISCO revision confusion
HiI own a STM32F469-Discovery Board bought in 2021. There seem to be (at least) two revisions of that board, "B" & "C" and maybe "A". Under "CAD Resources" are just schematics for Revision "B" and "C".If I try to run the supplied example for that boa...
Resolved! Unable to connect BlackPill via ST-link
Hi,When trying to connect the board via ST-link in CubeProgrammer i get the error: "No STM32 target found!..."; can't figure out what problem is preventing ST-link from finding the target.BlackPill is working properly, i can use it via DFU, but I wou...
