Affected doc / sectionRM0492 (STM32H503) → General-purpose timers → Master mode selection (MMS) (TIMx_CR2.MMS = 0000 “Reset”)Current wording (verbatim)“MMS = 0000 – Reset: the UG bit from the TIMx_EGR register is used as trigger output (tim_trgo). If...
why need to monitor txe flag and btf flag to transfer data after each byte.txe says data register is empty,btf and txe says need monitor after last byte. according to reference manual.but my question is how should i know i get ack after sending 1 by...
I’m implementing an audio clock source switching mechanism where the system runs on the internal audio clock if no external clock is detected. As soon as an external clock becomes available, it switches to use that external clock source.This works in...
I would like to set a 1Hz signal on the PC14 (RTC_OUT_CALIB). I have found a manual in document AN3371 (see picture in appendix). The code is also in the appendix. Unfortunately, nothing happens on the PC14 but the RTC works. If anyone has any idea w...
HelloCan the STM32H743 modify data at two non-consecutive peripheral addresses in a single DMA event，A DMA event changes two peripheral addresses，
Hello,I'm trying to port the ST IMX335 camera driver middleware to work with the RPi 2 IMX219. Everything works well with the IMX335, however after adjusting to reflect the IMX219 registers I get no image data and a Lane 0& 1 control error flag as so...
Hi everyone,I would like to know if it’s possible to debug an STM32 microcontroller without using an ST-Link, but instead with an FTDI FT4232HQ chip via its JTAG or SWD interface.If this is possible:How can I configure the debugger connection?Can it ...
Hi!I'm struggling to wrap my head around timers - I am trying to schedule some ADC reads of a current sense amplifier in a motor control setup.I have three center-aligned PWM waveforms being generated by Timer1, which successfully commutate a BLDC mo...
Hello, dear community!I have a problem with adding more than one button to my STM32 Button Box / joystick with buttons. I am using USB HID.I made it as simple as possible - only two buttons, simplest descriptor. The problem may be trivial, but after ...
I am using NUCLEO-G071RB. I am trying to generate an PWM pulse. I am using TIMER 3 Channel 2. - Clock Frequency = 64 MHzWith this setting I should get a HIGH pulse of 90 micro second, instead I get 80 or 40 micro seconds. When the Pre-scaler is incre...
