In the datasheet of the STM32F765ZI and many other datasheets I have read, the specification value of hysteresis voltage between Schmitt trigger switching levels is missing. There is a comment (8) under the table (here table 66 I/O static charasterit...
We want to realise a cheap measurement of a external voltage over a voltage divider with a STM32F765ZI processor. We calculate VIL with the formula "0,35*VDD-0,04" which is guaranteed by design. On base of this calulated VIL we calculate our voltage ...
Is there a way to connect them in parallel with some individual enable to reduce the outward interface of the board. ie maybe connect everything in parallel except for RST line or ??? any suggestions would be appreciated
I have a bootloader + 1 wire serial uploader codebecause of space restrictions it uses LL_ libraries for initialization.We have different hardware designs, when using PA2 as IO pin it works !when using PB4 as IO it does not !The main program uses HAL...
I'm trying to setup a GPS sensor (UBlox Max8Q) with a H745 Nucleo board using UART DMA using STM32CubeIDE. However, I’m having problems with setting up my board properly. My plan is to eventually do all my data acquisition on the M4 chip and do compu...
We are evaluating the use of ETM or ETB but have problems finding MCUs that support those features (or one of them). Sure we can dig into the data sheet of an MCU family but isn't there a possibility to filter for these features in some MCU finder?
Hello,I am using STM32L073V8T .I am trying wake up from standby with WKUP1 pin. It is PA0. According to techinical documents, low to high transition should wake MCU from standby. But, It doesnt work in my case. Is there any special configuration what...
As per image sub=7(not typecasted), sub1=28(typecasted). I don't understand why is sub giving wrong value I understand I have not typecasted but,each pointer variable is holding 4 byte value (i.e int type) then,typecasting must not be required isnt i...
Hi everyone,I built a custom board with STM32F429VIT with the following settings:Boot0=GND, Boot1=GNDHSE=25MHzI configured IAR project options as following:- use-Flash-loader checked;I am using IAR 8.10 with ST-Link-v2 (SWD) to develop the firmware. ...
