UCPD and DBCC (dead battery) doubts
According to RM0456, p. 3459So in addition to CCx pins also PB5 and PB14 (DBCCx) cannot be used. The above does not make much sense to me. I imagine (only imagine) that internally DBCC support is implemented like shown below and for "dead battery" to...
Resolved! Long delay in setting TIM status register bits
Hi,I am trying to use CC1 and CC3 inputs on TIM2 of STM32H7A3 to do some time-critial tasks (very ns fast time-stamping). I need to identify which CCxIF tiggered. Using STMCUBEIDE the skeleton interupt code worked fine in debug mode without the lines...
Resolved! ST Nucleo F767ZI USB not detected by PC
I've compiled my first program and I can't find a way to upload to the board.When I plug the USB, the onboard LED is lit, but my PC does not detect anything - I don't hear any "plug" sound, and I can't find any device in Device Manager (recognized no...
Stm32f405rgt6 custom board not detected on stm32programmer,]
hey, I'm developing a custom stm32f405rgt6 board. I'm using stlink for uploading code. I'm comparitively new to stm as i've only worked with blue pill. I get "Error: No STM32 target found! If your product embeds Debug Authentication, please perform a...
Resolved! Looking for an NXP MKL03Z32VFK4 alternative with great long-term availability
Hi there,I've been using the NXP Kinetis MKL03Z32VFK4 Ultra-Low Power Cortex-M0+ MCU in our products, and it's been working well, but due to a major redesign, I'm looking for alternatives, and ST MCUs are promising.Specifically, I'm concerned about l...
How to choose crystal speed?
I just was wondering how you guys proceed to choose an external crystal, specifically what speed it should have...The clock management with its tons of PLLs and dividers seems to be able to scale up almost any source to a desired frequency.for the L4...
Selecting GPIO in shared pins for STM32G030F6
In pins that share more than one GPIO, how do you set the GPIO to connect to the physical pin?For instance, for pins PA12/PA10 and PA11/PA9 one can remap them using SYSCFG_CFGR1 register. But is unclear for the rest of the pins. For example, TSSOP20 ...
QSPI Slave mode? PSSI in 2bit-packing mode? There must be a way...
I have an application which requires me to send unidirectional high-speed parallel data on preferably 2 (or 4) from several synchronous sources to an STM32. I'm thinking of using the U575, but that's not set in stone.My requirements do not seem to fi...
How to set Adc for maximum rate
I have design pcb for Stm32H723VGT6 ( 100 pins TQFP ) my job is read adc 12 bit and transfer over usb to PC . i have set sysclk to 550 MHz and ADC clock to 64 MHz so i got sample rate to 1.3 Msps but mcu are hot. So i have sysclk to 400 and ADC ...
