Hi, I need to use a 5V external clock for an stm32g473. The datasheet in table 39. High-speed external user clock characteristics says Vhsel is max Vdd, but Table 12. STM32G473xB/xC/xE pin definition says PF0 / OSC_IN is FT_a (five volt tolerant). Is...
Ok, this is perhaps esoteric, so maybe there is some research out there. I am looking at STM32U3 or STM32C5, but the problem applies to pretty much all CM33 based ST MCUs. The bus matrix implies a fast multiplexor for GPDMA (and SDMMC) to SRAM1. S...
I would like to connect a 12-bit ADC operating at 10MSps to the PSSI interface of the STM32N657 device. There is some confusion as to the nature of the clock source. The reference manual indicates that this may be either an input or an output. If c...
I'm using LPTIM1 in encoder mode and have noticed that, if there's jitter on one of the encoder signals the count will gradually creep up which should not be possible in encoder mode.This is on a decent encoder that's got an RC network (per the Bourn...
I started getting this message when I try to debug my code. However, there are currently no breakpoints in my code at all. I have gotten this in the past and I deleted and redownloaded the IDE which I really do not want to do again. I am running i...
Hiya. I'm having some trouble understanding how an STM32 MCU communicates with an image sensor via DCMI if they operate on different voltages.My STM32U5Gxxx operates on 3V3, whereas my selected image sensor has its VDDIO at 2V8 (max input of 3V1). Ho...
As addicated in DataSheet and CubeMX, there are two FDCAN1_Tx and two FDCAN1_RX in STM32G431CBT6. In my Prj, I used PA12 for Tx and PB8-BOOT0 for Rx, and my chip can only work in FDCAN_MODE_Ext._Loopback, and without any receive func be implemented. ...
How to configure the sysTick_Handler(), when we are setting the HCLK 386MHz in CubeMX and systemClock() is generated, but while configuring sysTick(), uint32_t SystemCoreClock = 64000000; already there in system_stm32h7xx_dualcore_boot_cm7_cm4.c(void...
Hi, I'm using a STM32F072's DAC to output a SIN and a COS wave. The problem is I can only output values up to approx. VDDA / 2. The DAC drives unity gain amplifiers to drive a 50 Ohm load. The DAC is connected directly to the amps, using the buffer ...
Hello,Can anyone tell me how to measure pulse width with the HRTIM? I need to measure a very short pulse from my time domain reflectometer. I am thinking of using the NUCLEO-H753ZI board with the STM32H753ZI MCU. All I know about measuring pulses wit...
